Key Takeaways
- A child can be included in a partner visa application as a dependent family member if they have not turned 23 when the application is made and they are dependent on the parent. After the 23rd birthday, the child can only be included if they rely on the parent financially because they are incapacitated for work.
- Age and family membership are tested at the time of application, so lodging the partner visa before the child's 23rd birthday is often the most urgent step in the whole application.
- A child who has turned 23 cannot be added to a partner visa after lodgement unless the incapacity exception applies, because only dependent children can be added while the application is undecided.
- Once a child holds the temporary partner visa as part of the family unit, the Department's policy states that dependency and membership of the family unit are not reassessed when the permanent visa is decided.
- The incapacity exception needs medical and functional evidence showing the loss of bodily or mental functions, its effect on work capacity, its history and the financial reliance it causes.
What happens to a child turning 23 partner visa application?
A child turning 23 partner visa application turns on one date: the date the application is made. If the child has not turned 23 when the partner visa application is lodged, and meets the other parts of the definition, the child can be included as a dependent family member. If the child has already turned 23, the child can only be included where they are wholly or substantially reliant on the parent for financial support because they are incapacitated for work due to the total or partial loss of bodily or mental functions.
That is the core of every child turning 23 partner visa question. Age is not judged on the day the case officer opens the file, and it is not judged on the day of grant. For the main eligibility test, age and family membership are fixed at the time of application. This is why families with a son or daughter who is 22 often face real urgency. A few weeks can decide whether the child is inside or outside the application.
This guide explains the child turning 23 partner visa rules in plain English. It covers the legal definitions, the exception for incapacity for work, what happens if the birthday falls before lodgement, between lodgement and the temporary visa, and between the temporary and permanent stages. It also explains Tribunal decisions that dealt with children aged 23 or older, the medical evidence needed for the incapacity exception, and other options when a child cannot be included. For a broad overview of every partner pathway, start with the complete guide to partner visas in Australia.
Who this child turning 23 partner visa guide is for
This guide is written for three groups. The first is a visa applicant who is about to lodge a partner visa and has a child who is 22 and close to the 23rd birthday. The second is a sponsor whose partner has an adult child who is still dependent. The third is a family who has already lodged and is worried about what the 23rd birthday means while the application is being processed.
The guide applies to the onshore Subclass 820 partner visa and its permanent Subclass 801 stage, the offshore Subclass 309 partner visa and its permanent Subclass 100 stage, and the Subclass 300 Prospective Marriage visa. The child turning 23 partner visa rules come from the same definitions in each pathway, but the criteria that apply later in processing differ, and those differences matter.
What this guide does not cover
This guide does not set out the evidence needed to prove financial dependency for a child aged 18 to 22. That is a separate topic. It also does not deal with the 18th birthday, which raises its own issues. The focus here is the age 23 cut-off and what a family can do when a child is close to it, at it or past it.
Why is 23 the age limit for a dependent child on a partner visa?
The age 23 limit comes from the Migration Regulations 1994, which define who counts as a dependent child and who counts as a member of the family unit. A child who has turned 18 but has not turned 23 can be included only if they are dependent on the parent or on the parent's spouse or de facto partner. A child who has turned 23 can be included only if they are dependent because of incapacity for work.
Regulation 1.12 sets out the meaning of member of the family unit. Under regulation 1.12(2)(b), a child or step-child of the family head, or of the family head's spouse or de facto partner, can be a member of the family unit if they are not engaged to be married and do not have a spouse or de facto partner, and they either have not turned 18, or have turned 18 but not 23 and are dependent, or have turned 23 and are dependent under paragraph 1.05A(1)(b). The definition of dependent child in regulation 1.03 follows the same age structure.
So the child turning 23 partner visa issue is not a policy preference that a case officer can waive. It is written into the definitions that the partner visa criteria rely on. A child who has turned 23 and is not incapacitated for work does not meet the definition, however close the family is and however much support the parent gives.
What "turned 23" means
A child turns 23 on their 23rd birthday. Under the regulations, a child who "has not turned 23" is a child whose 23rd birthday has not yet arrived. On the morning of the birthday, the child has turned 23. For a child turning 23 partner visa plan, the practical rule is simple: the application must be validly made before the birthday, not on it.
This is why the date of lodgement in ImmiAccount is so important. An application is made when it is validly lodged, which includes payment of the visa application charge and meeting the other validity requirements. A draft that sits unsubmitted in ImmiAccount has not been made. A family that starts the application but does not finish it before the birthday has not protected the child.
The marriage and de facto exclusion
The age 23 limit is not the only bar. A child of any age is excluded if they are engaged to be married or have a spouse or de facto partner. A child turning 23 partner visa case can therefore fail for two separate reasons: age, or the child's own relationship. Families sometimes overlook the second. If a 22 year old child is in a de facto relationship, they are not a dependent child even if they are under 23. That child needs their own visa pathway.
Dependent child and member of the family unit: what is the difference?
A dependent child is a defined term that focuses on the parent and child relationship, while member of the family unit is a wider defined term that covers a spouse or de facto partner, certain children and, in some visas, other relatives. In partner visas, both terms appear in the secondary criteria, and both use the same age 23 structure for children.
For a child turning 23 partner visa application, the distinction matters because different subclasses use different words. The Subclass 820 secondary criteria in clause 820.311 refer to an applicant who, at the time of application, is a dependent child of a person who applied for a Subclass 801 visa, or, in the case of a former Subclass 300 holder, a member of the family unit. The Subclass 309 secondary criteria in clause 309.311 refer to a member of the family unit of the primary applicant. The Subclass 300 secondary criteria in clause 300.311 also refer to a member of the family unit.
In practice, for a child of the primary applicant, both definitions lead to the same result on age. Under 18, the child qualifies if not married, engaged or in a de facto relationship. From 18 to the day before the 23rd birthday, the child must also be dependent. From the 23rd birthday, the child must be dependent because of incapacity for work. The partner visa document checklist explains the documents that sit around these definitions, such as birth certificates and custody documents.
Step-children and the sponsor's children
The definitions include step-children of the family head, and children of the family head's spouse or de facto partner. In a partner visa, the family head is the primary applicant. A child of the sponsor is not normally a visa applicant, because the sponsor is already an Australian citizen, permanent resident or eligible New Zealand citizen. The child turning 23 partner visa issue therefore usually concerns the primary applicant's own child or step-child, who needs to be included in the application to migrate.
What "dependent" means under regulation 1.05A
Regulation 1.05A(1) gives two separate ways to be dependent. The first, in paragraph 1.05A(1)(a), is financial dependency: the person is, and has been for a substantial period immediately before the relevant time, wholly or substantially reliant on the other person for financial support to meet basic needs for food, clothing and shelter, and that reliance is greater than reliance on any other person or source. The second, in paragraph 1.05A(1)(b), is dependency because of incapacity: the person is wholly or substantially reliant on the other person for financial support because they are incapacitated for work due to the total or partial loss of bodily or mental functions.
For a child aged 18 to 22, either limb can be used. For a child who has turned 23, only the second limb counts for membership of the family unit. This is the legal heart of the child turning 23 partner visa rule. After the birthday, financial dependency on its own is not enough to bring the child into the family unit.
When does age 23 matter: at application or at decision?
For the main eligibility test, age 23 matters at the time of application. Clauses 820.311, 309.311 and 300.311 all ask whether the child is a dependent child or a member of the family unit at the time the application is made. A child who is 22 and dependent on that date satisfies the time of application criterion, even if the 23rd birthday arrives the next week.
But the time of application criterion is not the end of the child turning 23 partner visa analysis. Each temporary partner visa also has criteria that must be met at the time of decision. Those criteria are worded differently in each subclass. The sections below explain each stage in turn, because the risk to a child turning 23 partner visa applicant changes as the application moves from lodgement to the temporary grant and then to the permanent grant.
The three moments that matter
There are three moments in a child turning 23 partner visa case. The first is lodgement, when the time of application criteria are tested. The second is the decision on the temporary visa, which is the Subclass 820, Subclass 309 or Subclass 300 visa. The third is the decision on the permanent visa, which is the Subclass 801 or Subclass 100 visa. A child who turns 23 before the first moment faces the hardest position. A child who turns 23 after the first moment is in a much better position, but the family still needs to understand the time of decision criteria. The guide to Subclass 820 vs Subclass 801 explains how the two stages fit together.
Why lodgement planning comes first
Because the time of application test is fixed, the most important child turning 23 partner visa decision is when to lodge. Many families assume they can lodge when the relationship evidence is perfect and then add the child later. That assumption can be costly. As explained below, a child can only be added after lodgement if they are a dependent child at that time, and a child who has turned 23 without incapacity cannot be added at all. Planning the lodgement date around the child's birthday is often the single most valuable step in a child turning 23 partner visa matter.
What if the child turns 23 before the partner visa is lodged?
If the child turns 23 before the partner visa application is lodged, the child cannot be included as a dependent child or member of the family unit unless they are incapacitated for work due to the total or partial loss of bodily or mental functions and are wholly or substantially reliant on the parent for financial support because of that incapacity. Without that incapacity, the child needs a separate visa pathway.
This is the hardest child turning 23 partner visa position, and it is often reached by accident. A couple may delay lodgement to gather more evidence of the relationship, to meet a de facto relationship requirement, to resolve a sponsorship limitation, or simply because they did not know about the age limit. By the time they lodge, the child has turned 23.
Can the family still lodge on time?
Sometimes, yes. If the birthday has not yet arrived, the question is whether the partner visa can be validly lodged before it. That depends on whether the primary applicant and sponsor already meet the requirements needed for a valid application and a reasonable prospect of grant. For example, a de facto couple usually needs to meet the relationship requirements explained in the guide to the de facto partner visa in Australia. An onshore applicant also needs to consider their immigration status, including whether Schedule 3 criteria for a partner visa apply.
A child turning 23 partner visa deadline should never push a couple into lodging an application that is likely to be refused. A refused partner visa does not help the child, and it can create new problems for the primary applicant. The right approach is to check, early and carefully, whether the application can be made validly and properly before the birthday, and to build the strongest file possible in the time available. Further relationship evidence can usually be provided after lodgement, but the core requirements must already be met.
What if the birthday has already passed?
If the 23rd birthday has already passed, the family has two questions to answer. First, does the incapacity exception apply? Second, if it does not, what other visa options are available to the child? Both questions are covered later in this guide. What a family should not do is describe the child in a way that does not match the facts. Information given in a partner visa application is assessed against public interest criterion 4020, and false or misleading information can have serious consequences for the whole family. The guide on why partner visas get refused explains how integrity concerns affect outcomes.
What if the child turns 23 after lodgement but before the temporary visa is granted?
If the child was a dependent child or member of the family unit when the application was made, turning 23 afterwards does not undo the time of application criterion. The child remains a valid secondary applicant. However, each temporary partner visa also has a time of decision criterion for secondary applicants, and that criterion must be checked for the specific subclass.
This is the most common child turning 23 partner visa situation, because partner visa processing can take a long time. A child who was 22 at lodgement may be 23 or 24 by the time the temporary visa is decided. The guide to Subclass 820 visa processing time explains why processing periods vary.
The Subclass 820 time of decision criterion
For a Subclass 820 secondary applicant, clause 820.321 applies at the time of decision. Under paragraph 820.321(a), the child must be a person who is dependent on, or a member of the family unit of, the primary applicant, who has been granted the Subclass 820 visa. The Department's policy notes that a secondary applicant cannot be granted the Subclass 820 visa until the primary applicant is granted their Subclass 820 visa.
The wording of the time of decision criterion is different from the time of application criterion. It refers to being "dependent on" the primary applicant as an alternative to being a member of the family unit. How that wording applies to a child who was 22 at lodgement and 23 or older at decision depends on the facts, including whether the child is still dependent on the parent at that later time. A child turning 23 partner visa case in the Subclass 820 stream should be reviewed before the decision is made, so that current evidence of the child's dependency is on file when the case officer assesses it.
The Subclass 309 and Subclass 300 time of decision criteria
The Subclass 309 and Subclass 300 visas also contain time of decision criteria for secondary applicants. For the Subclass 300 visa, the Department's policy explains that clause 300.321 requires the secondary applicant to continue to be a member of the family unit of a person who satisfied the primary criteria and holds a Subclass 300 visa. The Subclass 309 secondary criteria also link the secondary applicant to the primary applicant at the time of decision.
For a child turning 23 partner visa applicant in either of these streams, the practical point is the same. Lodging before the birthday protects the time of application criterion, but the family should still expect the case officer to look at the child's circumstances when the temporary visa is decided. Keeping the evidence current, and telling the Department about changes, is part of protecting the child through processing.
Changes the Department must be told about
Applicants must tell the Department about relevant changes in circumstances while an application is being processed. For a child turning 23 partner visa applicant, relevant changes may include the child becoming engaged, marrying, entering a de facto relationship, moving out of the parent's household, or starting full-time work that ends the financial reliance. The guide to Form 1022 change of circumstances explains how to notify these changes. A child who marries or enters a de facto relationship before the temporary visa is decided may stop meeting the secondary criteria regardless of age.
Requests for more information
Case officers often ask for updated evidence about adult secondary applicants. A request may come as a section 56 request for more information, or, where the case officer has adverse information, as a section 57 natural justice letter. Response periods are short and strictly applied. In a child turning 23 partner visa matter, a weak response to one of these letters is one of the most common ways a secondary applicant is refused.
What if the child turns 23 between the temporary and permanent partner visa?
If the child holds the temporary partner visa as a secondary applicant, turning 23 before the permanent stage does not, by itself, stop the child from moving to the permanent visa with the parent. The Department's policy states that at the permanent stage there is no requirement for the secondary applicant to have remained a member of the family unit of, or dependent on, the primary applicant.
For the Subclass 801 visa, the Department's policy explains that clause 801.321 requires the secondary applicant to satisfy certain visa related criteria at the time of decision, such as holding the Subclass 820 visa granted on the basis of being the dependent child or member of the family unit of the primary applicant, and the primary applicant being granted the Subclass 801 visa. The policy states that delegates do not need to assess either membership of the family unit or dependency at the time of decision. The Subclass 100 policy says the same about clause 100.321.
This is reassuring for many child turning 23 partner visa families. Once the child is granted the temporary visa as part of the family unit, the 23rd birthday is no longer the central risk. The child moves with the parent to the permanent stage, subject to the other criteria, such as health and character requirements, that still apply to them.
The permanent stage still has requirements
The permanent stage is not automatic. The child must still meet the public interest criteria that apply to secondary applicants, and must notify the Department of changes. The policy also notes that a family member's temporary visa may be considered for cancellation if there is substantiated evidence of fraud affecting the earlier decision to accept them as a member of the family unit. This is another reason why the child turning 23 partner visa evidence must be accurate from the start. A family facing a cancellation concern should read the page on visa cancellations and get advice quickly.
What if the primary applicant's relationship ends?
If the primary applicant's relationship with the sponsor ends before the permanent visa is granted, the primary applicant may still be eligible in limited circumstances, such as where family violence provisions apply. The child's position follows the primary applicant's. The page on family violence partner visa provisions and the guide to Subclass 820 relationship breakdown explain these rules. In a child turning 23 partner visa case, the age of the child does not change the primary applicant's options, but it can affect what the child can do if the primary applicant's application fails.
Can a child who has turned 23 be added to a partner visa after lodgement?
No, not unless the child is incapacitated for work in the way the regulations describe. Regulation 2.08B allows dependent children, and only dependent children, to be added to a partner visa application after lodgement while the primary applicant's application is undecided. A child who has turned 23 and is not dependent because of incapacity is not a dependent child, so the regulation cannot be used for them.
The Department's policy for the Subclass 820 visa explains that regulation 2.08B allows dependent children to be added at the applicant's written request, usually by attaching Form 1436 in ImmiAccount. The Subclass 309 and Subclass 300 policies say the same. This creates a hidden child turning 23 partner visa trap. A family may plan to lodge first and add the child later. If the child turns 23 in between, the door closes.
Adding a child aged 18 to 22 after lodgement
A child aged 18 to 22 who is dependent on the parent can be added under regulation 2.08B, if the requirements of that regulation are met and the primary applicant's application has not been decided. But the child must meet the definition on the day they are added, which includes proving dependency at that time. Leaving the addition until the last weeks before the 23rd birthday adds pressure and risk. A child turning 23 partner visa plan should treat adding a child after lodgement as a fallback, not a strategy.
Subclass 445 Dependent Child visa
Where a parent has already been granted a Subclass 309 visa, the Department's policy explains that a dependent child who was not included or added before grant may be sponsored for a Subclass 445 Dependent Child visa before the Subclass 100 visa is granted. This is a separate application with its own criteria, and it still depends on the child meeting the definition of dependent child. It does not help a child who has turned 23 without incapacity. Families in this child turning 23 partner visa position should get advice on the Subclass 445 criteria before relying on it.
The incapacity for work exception for a child aged 23 or older
A child aged 23 or older can still be a member of the family unit if they are wholly or substantially reliant on the parent for financial support because they are incapacitated for work due to the total or partial loss of bodily or mental functions. This is the only route for a child who has turned 23 to be included as a dependent family member in a partner visa application.
The exception comes from paragraph 1.05A(1)(b) of the Migration Regulations. It has three parts, and each part must be shown. First, the child must be incapacitated for work. Second, the incapacity must be due to the total or partial loss of bodily or mental functions. Third, the child must be wholly or substantially reliant on the parent for financial support because of that incapacity. A child turning 23 partner visa application that relies on the exception has to deal with each of these elements, not only the medical condition.
Incapacitated for work
The first element is about the child's capacity to work, not simply whether they are working. A child who is studying full time, or who is unemployed because jobs are scarce, is not incapacitated for work in the sense the regulation means. The question is whether the loss of bodily or mental functions prevents the child from working, or substantially limits their capacity to support themselves through work. The evidence must speak to work capacity directly.
Total or partial loss of bodily or mental functions
The second element requires a loss of bodily or mental functions, which may be total or partial. The regulation does not list particular conditions, and there is no closed category. What matters is the effect on the child's functions and, through that, on their capacity for work. Medical evidence should describe the functional loss, not only the diagnosis.
Reliance because of the incapacity
The third element links the financial reliance to the incapacity. The child must be wholly or substantially reliant on the parent for financial support, and the reason for that reliance must be the incapacity. A child who is incapacitated but supported mainly by a government benefit in their home country, by another relative or by their own income may face questions on this element. In a child turning 23 partner visa case relying on the exception, the evidence should show who pays for the child's needs and why.
The exception is not limited to children who migrate
A child aged 23 or older who meets the incapacity exception is a member of the family unit whether or not they migrate. The Department's partner visa application form explains that children of any age who have a total or partial loss of bodily or mental functions that stops them earning a living are regarded as dependent and part of the family unit, whether or not they migrate. Such children must be declared in the application. Members of the family unit who are not applicants are also generally required to meet health criteria, and the Subclass 820 criteria in subclause 820.224(1A) set out the public interest criteria that non-applicant family members must meet.

What evidence supports the incapacity exception?
The incapacity exception is supported by independent medical and functional evidence that explains the loss of bodily or mental functions, how it affects the child's capacity for work, when it began, and how the child relies on the parent for financial support because of it. A child turning 23 partner visa application relying on the exception should not depend on a family statement alone.
The evidence needed differs from case to case, and it must always reflect the child's real circumstances. The categories below explain what case officers usually expect to see. They are not a checklist to be filled regardless of the facts. Each document should come from a proper source and say what that source can actually confirm.
Medical reports from treating practitioners
The strongest evidence usually comes from the practitioners who treat the child. A useful report explains the practitioner's qualifications, how long they have treated the child, the functional loss they observe, its likely duration, and its effect on the child's capacity to work and to live independently. A report that names a condition but says nothing about function or work capacity is far less useful in a child turning 23 partner visa case.
Functional and capacity assessments
Where available, formal assessments of work capacity or daily functioning can be powerful. These may include occupational therapy reports, disability assessments, rehabilitation reports or assessments carried out for benefits or support schemes in the child's home country. They help show the "incapacitated for work" element in practical terms.
Onset and history
Evidence of when the loss of function began helps show that the incapacity is real and lasting. Hospital records, older medical letters, school or education records showing support needs, and records of past treatment can all help. A history that only begins in the weeks before lodgement can raise questions, even where the condition is real. A child turning 23 partner visa file should show the history as it actually happened.
Evidence of financial reliance because of the incapacity
The financial element still needs proof. This may include evidence of money transfers from the parent, payment of medical or care costs, payment of rent or housing, and evidence that the child does not have income from work. The financial evidence should connect to the incapacity, showing that the parent supports the child because the child cannot work.
Translations and certification
Documents not in English need accurate English translations. The Form 80 guide and the partner visa relationship evidence guide explain how evidence is usually prepared and presented in partner applications. Medical evidence about an adult child is sensitive, so it should be uploaded only to the correct applicant and category in ImmiAccount.
Tribunal decisions on children aged 23 or older in partner visa cases
Tribunal decisions show that the age 23 limit and the incapacity exception are contested in partner visa review. Several decisions involving secondary applicants aged 23 or older, or claims of incapacity for work, were remitted to the Department for reconsideration. Each decision turned on its own facts and evidence, and none is a promise about any other case.
In 2421153 (Migration) [2025] ARTA 2911, a Subclass 309 matter, the reported issue was an adult child secondary applicant whose younger siblings had been granted visas, and whether the applicant was a dependent member of the family unit aged 23 or older at the time of application. The matter was remitted to the Department.
In Shah (Migration) [2025] ARTA 565, also a Subclass 309 matter, the reported issue was whether the visa applicants met the definition of member of a family unit of their mother, where the children were over the age of 23. The matter was remitted to the Department.
In 2501448 (Migration) [2025] ARTA 2938, a Subclass 309 matter, the reported issue concerned a secondary applicant claimed to be a member of the family unit because of incapacity for work. The matter was remitted to the Department.
In 2609288 (Migration) [2026] ARTA 1333, another Subclass 309 matter, the reported issue was a young adult son as a secondary applicant to his mother's application, dependency, and whether he was wholly or substantially reliant because of incapacity for work. The matter was remitted to the Department.
What these decisions show
These decisions show that child turning 23 partner visa questions are decided on evidence, and that a refusal by the Department is not always the end. They also show the cost of getting the evidence wrong the first time. Review takes time, and the family lives with uncertainty while it runs. The better course is to prepare the child turning 23 partner visa evidence properly before the Department decides. The guide to what to expect at an ART review explains the review process.
Why lodging before the 23rd birthday matters so much
Lodging before the 23rd birthday matters because a child aged 18 to 22 can be included on the basis of ordinary financial dependency, while a child aged 23 or older can only be included if they are incapacitated for work. One day can change the legal test from one the child can meet to one the child cannot meet.
For most families, a child turning 23 partner visa deadline is the most urgent date in the whole application. It is more urgent than gathering the last few photographs or another Form 888. Relationship evidence can usually be added after lodgement. A missed birthday cannot be undone.
Working backwards from the birthday
Good child turning 23 partner visa planning works backwards from the birthday. The family needs time to confirm the couple meets the relationship requirements, to collect identity and civil documents for every applicant, to prepare the child's dependency evidence, to complete the forms, and to deal with any sponsorship limitations. Payment of the visa application charge must also be arranged in advance, because an application is not validly made until the charge is paid.
Leave a margin for problems
ImmiAccount can be slow or unavailable. Payment cards can be declined. Documents can turn out to be missing. A child turning 23 partner visa plan should never aim to lodge on the last day before the birthday. The family should aim to lodge well before it, with time to fix problems. Where the deadline is close, the guide to urgent immigration lawyer advice explains how to get help quickly.
Onshore applicants and location at lodgement
For an onshore Subclass 820 application, each applicant generally needs to be in Australia when the application is made. For an offshore Subclass 309 application, applicants generally need to be outside Australia. A child turning 23 partner visa plan must therefore consider where the child physically is on the lodgement date, as well as the child's age. A family that lodges onshore while the child is overseas may find that the child cannot be included in that application.
Bridging visas for the child
A child included in an onshore Subclass 820 application who holds a substantive visa will usually be granted a bridging visa when that visa ends. The guide to bridging visas in Australia, the guide to Bridging Visa A and the guide to Bridging Visa B explain how bridging visas work, including travel. The guide to working while a Subclass 820 visa is pending explains work rights. A child who travels without the right bridging visa may face problems returning to Australia.
What if the child is refused as a secondary applicant?
If the Department refuses the child as a secondary applicant, the family should read the refusal decision carefully and act quickly, because review deadlines are short and strictly applied. Depending on the visa and the circumstances, the refusal may be reviewable by the Administrative Review Tribunal, which replaced the Administrative Appeals Tribunal on 14 October 2024.
A child turning 23 partner visa refusal often turns on one of a small number of findings: the child had turned 23 at the time of application, the child was not dependent, the child was in a relationship, or the evidence of incapacity was not accepted. Each finding needs a different response. The page on partner visa refusals, the guide to partner visa refused appeal options and the page on visa refusals explain the general options. The guide to a partner visa after a visa refusal explains what can follow.
When Tribunal review is not the end
Where the Tribunal affirms a refusal, there may be limited further options, such as judicial review for legal error. These are narrow remedies. The priority in a child turning 23 partner visa case is to get the application right at the Department stage, and if a refusal happens, to apply for review on time with proper evidence. The guide to choosing a visa appeal lawyer explains what to look for.
Other visa options when a child cannot be included
When a child has turned 23 and does not meet the incapacity exception, the child cannot migrate as part of the parent's partner visa. The child needs their own visa pathway, assessed on their own circumstances. This is often hard news for a family, but it is better faced early than discovered after the birthday has passed.
Other pathways are assessed under their own criteria. Depending on the child's age, qualifications, work history and plans, these may include student visas, skilled or employer sponsored visas, working holiday visas where eligible, or visitor visas for family visits. Some family sponsored visas may later become available once the parent holds permanent residence or citizenship, but each has its own requirements and none follows automatically from the parent's partner visa. A child turning 23 partner visa outcome therefore calls for a separate assessment of the child's own options.
Do not rely on a visitor visa as a pathway
A visitor visa is for temporary visits. It is not a way to keep an adult child in Australia while the parent's partner visa is processed. Visitor visas may carry conditions such as a "no further stay" condition, which can restrict later applications in Australia. The guide on moving from a tourist visa to a partner visa in Australia and the guide to condition 8503 and the Subclass 820 explain how visitor visa conditions interact with later applications.
Plan the parent's application and the child's pathway together
Where a child cannot be included, the parent's application and the child's own plans should still be considered together. Timing, location, travel and evidence for one person can affect the other. A coordinated child turning 23 partner visa strategy avoids decisions that solve one person's problem while creating a new one for the other.
Common child turning 23 partner visa mistakes
The most common child turning 23 partner visa mistakes are delaying lodgement past the birthday, assuming the child can be added later, relying on financial dependency for a child who has already turned 23, and leaving out a non-migrating incapacitated adult child who must be declared. Each of these mistakes is avoidable with early advice.
Other mistakes include failing to tell the Department that the child has married or entered a de facto relationship, presenting medical evidence that names a condition but does not explain work capacity, and responding late or thinly to requests for information. Some families also prepare their own application and only seek help after a refusal. The guides on partner visa lawyer vs DIY, hiring an immigration lawyer after visa lodgement and getting an immigration lawyer second opinion explain when outside help adds value.
The relationship evidence still matters
A child turning 23 partner visa application is still a partner visa application. The child can only be granted a visa if the primary applicant is. That means the couple's evidence across the four assessed aspects (financial aspects, the nature of the household, social aspects and the nature of the commitment), the one partner visa relationship statement and the supporting witness statements on Form 888 all still need care. The 820 partner visa evidence checklist explains the wider evidence picture.

What the firm does on a child turning 23 partner visa matter, step by step
First, the firm confirms the child's exact date of birth from identity documents and works out the last safe lodgement date, with a margin for problems. Second, it checks whether the couple already meets the relationship and validity requirements needed to lodge before that date, and identifies anything that could stop a valid application, such as a sponsorship limitation or an onshore status issue. Third, it checks the child's own status: whether the child is engaged, married or in a de facto relationship, where the child will be on the lodgement date, and whether the child is dependent.
Fourth, where the child has turned 23 or is about to, the firm assesses whether the incapacity exception may apply. It identifies the medical and functional evidence needed to address each element, and explains to the family what treating practitioners should be asked to cover. The firm presents the child's own circumstances and evidence in the form the law requires. It does not create or shape evidence to fit a result.
Fifth, the firm prepares and lodges the application with the child included, or advises plainly where the child cannot be included and what other pathways may be open. Sixth, it monitors the application through processing, prepares responses to requests for information, updates the child's evidence before the temporary visa decision, and manages notifications of changes. Where a child is refused, the firm advises on review options within the short time allowed.

Frequently Asked Questions
Can my child be included in my partner visa if they are 22?
Yes, a child who is 22 when the partner visa application is made can be included if they are dependent on you or your partner and are not engaged, married or in a de facto relationship. The age test is applied at the time of application. This means the application must be validly lodged in ImmiAccount, with the charge paid, before the child's 23rd birthday. If the birthday passes first, the child can only be included under the incapacity for work exception.
What happens in a child turning 23 partner visa case if the birthday is next month?
The family should treat lodgement as urgent and check straight away whether the partner visa can be validly made before the birthday. That means confirming the couple meets the relationship and validity requirements, collecting the child's identity and dependency evidence, and arranging payment of the charge. A margin should be left for technical or document problems. Lodging an application that is likely to be refused does not help the child, so speed must be matched with a properly prepared file.
Does my child need to stay under 23 until the partner visa is granted?
No, the main eligibility test asks whether the child was a dependent child or member of the family unit when the application was made. A child who was 22 at lodgement does not fail that test by turning 23 during processing. However, each temporary partner visa also has time of decision criteria for secondary applicants. For example, the Subclass 820 criterion refers to the child being dependent on, or a member of the family unit of, the primary applicant. Current evidence should be on file before the decision.
Is a child turning 23 partner visa applicant reassessed at the permanent stage?
No, the Department's policy for the Subclass 801 and Subclass 100 visas states that delegates do not need to assess dependency or membership of the family unit when the permanent visa is decided. The child must hold the temporary partner visa granted on the basis of being part of the primary applicant's family unit, and the primary applicant must be granted the permanent visa. Other criteria, such as health, character and public interest criteria, still apply to the child.
Can I add my 23 year old child to my partner visa after lodging?
No, unless the child is incapacitated for work due to the total or partial loss of bodily or mental functions and relies on you financially because of that incapacity. Regulation 2.08B allows only dependent children to be added to an undecided partner visa application. A child who has turned 23 without that incapacity is not a dependent child under the regulations. This is why families should not plan to lodge first and add an older child later.
What does incapacitated for work mean for a partner visa child over 23?
It means the child cannot work, or their capacity to support themselves through work is substantially limited, because of a total or partial loss of bodily or mental functions. Being a student, being unemployed or living in a place with few jobs is not the same as incapacity for work. The child must also be wholly or substantially reliant on the parent for financial support because of the incapacity. Each of these elements must be shown with evidence.
What medical evidence is needed for a child turning 23 partner visa incapacity claim?
Reports from treating practitioners are usually central. They should explain the practitioner's qualifications, how long they have treated the child, the loss of function they observe, its likely duration and its effect on the child's capacity to work. Formal functional or capacity assessments, hospital records and older medical letters help show onset and history. Financial evidence should show the parent supports the child because the child cannot work. A diagnosis alone, without functional detail, is usually not enough.
Does a child over 23 with an incapacity have to be declared if they are not migrating?
Yes, a child of any age who meets the incapacity exception is treated as part of the family unit whether or not they migrate, and must be declared in the application. Family members who are not applicants are generally still assessed against health criteria. Leaving such a child out can create problems for the primary applicant, including questions about whether the information given in the application was complete and accurate.
Can a married child under 23 be included in a partner visa?
No, a child of any age who is engaged to be married, married or in a de facto relationship is excluded from the definitions of dependent child and member of the family unit. Age is only one part of the test. A 21 or 22 year old child who is in a de facto relationship cannot be included even though they are under 23. If the child's relationship status changes during processing, the Department must be told.
Is the child turning 23 partner visa rule the same for onshore and offshore applications?
Yes, the age 23 structure comes from the same definitions in the Migration Regulations, so it applies to the Subclass 820, Subclass 309 and Subclass 300 visas. The differences lie in the time of decision criteria for each subclass and in the location rules at lodgement. Onshore applicants generally need to be in Australia when the application is made, and offshore applicants generally need to be outside Australia. The child's location on the lodgement date therefore matters as well as age.
What happens if the Department refuses my child as a secondary applicant?
The family should read the decision record carefully and get advice quickly, because review deadlines are short and strictly applied. Depending on the visa, the refusal may be reviewable by the Administrative Review Tribunal. Common reasons include the child having turned 23 before lodgement, a finding that the child was not dependent, the child being in a relationship, or the incapacity evidence not being accepted. Each reason calls for a different response and different evidence.
Have Tribunal cases dealt with children over 23 in partner visas?
Yes, several Subclass 309 decisions dealt with secondary applicants aged 23 or older or claims of incapacity for work, and were remitted to the Department. Examples include 2421153 (Migration) [2025] ARTA 2911, Shah (Migration) [2025] ARTA 565, 2501448 (Migration) [2025] ARTA 2938 and 2609288 (Migration) [2026] ARTA 1333. Each decision turned on its own facts and evidence, so none shows how another case will be decided.
Can financial support alone keep a child over 23 in the family unit?
No, for a child who has turned 23, financial reliance alone does not make them a member of the family unit. Regulation 1.12 only includes a child aged 23 or older who is dependent under paragraph 1.05A(1)(b), which requires reliance because of incapacity for work. Ordinary financial dependency under paragraph 1.05A(1)(a) is available only to a child aged 18 to 22. Paying a child's living costs, however generous, does not change this.
What visa options does a child over 23 have if they cannot join the partner visa?
The child needs their own visa, assessed on their own circumstances. Depending on their age, qualifications, work history and plans, options may include student, skilled, employer sponsored or working holiday visas, or visitor visas for short family visits. Some family sponsored visas may become relevant once the parent holds permanent residence or citizenship, but each has its own requirements. None follows automatically from the parent's partner visa grant.
Does a step-child turning 23 face the same partner visa rules?
Yes, the definitions include step-children of the family head and children of the family head's spouse or de facto partner, and the same age structure applies. A step-child under 18 can be included if not married, engaged or in a de facto relationship. From 18 until the 23rd birthday, the step-child must also be dependent. From the 23rd birthday, the step-child must be dependent because of incapacity for work.
Should we wait for stronger relationship evidence before lodging if our child is nearly 23?
Usually not, if the couple already meets the requirements for a valid and properly supported application. Further relationship evidence can generally be provided after lodgement, but a passed birthday cannot be reversed. The core requirements, such as the relationship requirements and any sponsorship limitations, must already be met when the application is made. The balance between timing and evidence should be assessed case by case before the birthday.
