Subclass 445 and adult children in 2026: when an older child still counts as dependent
Turning 18 does not by itself take a child out of Australia's Dependent Child visa (Subclass 445) pathway. On the Department of Home Affairs Dependent Child visa (Subclass 445) page, the age test offers two alternatives: the child is under 18, or the child is over 18 and financially dependent on the parent who holds a temporary Partner or Dependent Child visa. A separate item on the same page addresses applicants over 18 who have a disability, so adulthood moves the question from the child's birthday to the basis on which an adult child still relies on the parent.
The visa is a bridge rather than a destination. It attaches to a parent who is midway through the Partner process on a temporary visa, and once it is granted the page requires the child to apply to be added to that parent's permanent Partner visa application. That sequencing matters more for adults than for minors: dependency is not a snapshot taken at birth or at lodgement, it is a condition that has to run alongside the parent's own case. The following is general reference material rather than advice on one family's position; requirements change, and the current position should be checked against the Department's official pages and the Migration Regulations 1994.
Does turning 18 end eligibility for the Subclass 445?
No. The page states the age criterion as being either under 18, or over 18 and financially dependent on the parent holding the temporary Partner or Dependent Child visa. No upper age limit is attached to the adult route, so the enquiry is about the nature of the reliance rather than the number of years since the birthday.
The parent's own visa is part of the same test. Eligibility requires dependence on a parent holding a Subclass 309 (Partner (Provisional)), Subclass 820 (Partner (Temporary)) or Subclass 445 visa. The Migration Regulations 1994 and the Department's PAM3 guidance refer to a wider group of partner-related temporary subclasses, including 310 and 826, so a parent holding something outside the three listed on the official page should have their visa category checked against current instruments. Once granted, the child must apply to be added to the parent's permanent Partner visa application, and a child applying inside Australia cannot hold another visa carrying a "No further stay" condition.
The underlying definition is worded slightly differently. Regulation 1.03 of the Migration Regulations 1994 defines a dependent child as a child or step-child who is unmarried and not in a de facto relationship, and who is either under 18 or, if 18 or over, dependent on the parent or unable to work because of a total or partial loss of bodily or mental function. The Department of Home Affairs page expresses the adult case as financial dependency and handles functional loss through a separate disability evidence item, which is why the two are worth reading together rather than treating either one as the whole rule.
What does "financially dependent on the parent" actually cover?
The page defines the relevant support by reference to basic needs: food, shelter and clothing. It also asks how long the support has been provided, so the question is not only who pays today but how far back the pattern runs. The evidence named for this is bank statements, money transfers and rent receipts.
No monetary threshold or minimum transfer amount appears on the page, which points to a qualitative test assessed on a pattern of documented support rather than on a number. Household wealth, in that sense, is not the answer on its own. A family with substantial assets can still fail the description if the adult child pays their own rent and living costs from employment and the parent only funds discretionary spending, while a far smaller amount used consistently to meet recurring basics fits the wording more naturally. Assume, hypothetically, an applicant aged 23 renting a one-bedroom apartment in a city where the parent does not live: the documents that speak to the test would be the rent receipts, the recurring transfers that cover them, and statements showing the applicant has no independent income base absorbing those costs.
Where does full-time study fit?
Older explanations of the dependent child definition include full-time study as a route for someone over 18. The Department of Home Affairs page does not present study as a standalone alternative; it states the adult case as financial dependency, with disability handled separately. A university place is therefore best treated as the context explaining why reliance continues, not as a substitute for it — whoever pays tuition, rent and day-to-day living costs still has to be documented. Because the Department of Home Affairs page and the Migration Regulations 1994 differ in emphasis, the current legislative definition should be confirmed rather than assumed.
When does disability, rather than money, carry the claim?
For applicants over 18 with a disability, the page asks for evidence from a qualified medical practitioner that the applicant has a total or partial loss of mental or bodily function that stops them from working. Two features follow from that wording. The assessment must come from a qualified practitioner, and it has to connect functional loss to an inability to work; a diagnosis in isolation does not say what the page asks for. The requirement also sits in a different place from the financial evidence set, though it does not displace the other criteria such as health, character or sponsorship.
Financial dependency or disability: which route fits this applicant?
| Financial dependency | Disability | |
|---|---|---|
| Basis on the page | Over 18 and financially dependent on the parent holding the temporary Partner or Dependent Child visa | Over 18 with a total or partial loss of mental or bodily function that stops the applicant from working |
| What the evidence must show | Reliance for basic needs — food, shelter and clothing — and how long the support has been provided | The functional loss and its effect on the ability to work, assessed by a qualified medical practitioner |
| Documents named | Bank statements, money transfers, rent receipts | Evidence from a qualified medical practitioner |
| Typical exposure | Short evidence window, or spending that cannot be tied to basic costs | Clinical material that does not link impairment to inability to work |
| Common to both | Health, character, sponsorship, Australian values statement where 18 or over | Same |
Who has to sponsor the application, and what blocks it?
The child must be sponsored by the same person who sponsored or nominated the parent's permanent Partner visa application, and the sponsorship has to be approved before the visa can be granted. This is where family structure and timing intersect: the sponsor is fixed by reference to the parent's own case, not chosen afresh for the child.
The sponsorship rules carry hard edges. If the sponsor, or their spouse or de facto partner, has a pending charge for a registrable offence, the Department states it will refuse both the sponsorship and the visa application. If there is a registrable offence conviction, sponsorship can be approved only in very limited circumstances. Separate from sponsorship, any debt owed to the Australian Government must be repaid or covered by a formal arrangement to repay.
What else changes once the applicant is 18?
The applicable requirements turn on more than one age threshold:
- Australian values statement. The applicant must have read, or had explained to them, the Life in Australia booklet, and must sign the Australian Values Statement confirming they will respect the Australian way of life and obey Australian laws.
- Character documents. Children over 16 must provide Form 80, plus a police certificate from every country where they spent 12 months or more in the last 10 years since turning 16. For Australian checks only Australian Federal Police National Police Certificates applied for under Code 33 – Immigration/Citizenship are accepted, and those certificates are valid for 12 months from issue. Military service records or discharge papers are required where the applicant served in the armed forces of any country.
- Health. The child, and any dependent children applying with them, must meet the health requirement.
- Relationship evidence. Birth, marriage, adoption or officially issued family status documents establish the link to the visa-holding parent.
- Lodgement mechanics. The visa is applied for on paper using Form 918, sent to the Child and Other Family Processing Centre in Perth with prepaid postage, forms completed in English and certified copies rather than originals. The application charge must be paid before posting, and the Department states it will not refund the application fee if the application is refused.
Why the parent's own timeline carries as much weight
Eligibility is written around dependence on a parent who currently holds a specified temporary visa, which means the adult child's case has to be lodged while the parent is still at that stage. If the parent has already moved beyond it, the description of the qualifying parent on the official page no longer matches. The Migration Regulations 1994 make the same point in decision terms — that the parent must still be a visa-holding parent and the applicant still their dependent child when the decision is made — and the Department's PAM3 guidance describes a practice of verifying that dependency has not materially changed where it was assessed more than six months earlier. Those procedural points sit in the Regulations and PAM3 guidance rather than in the published eligibility criteria, so the current version of those instruments governs.
Two mechanical consequences follow for the applicant inside Australia. They need to remain lawful while the application is processed, and if their current visa expires before a decision, a bridging visa starts and keeps them lawful. The page also requires notification of changes such as contact details, passport details or relationship status, which is consistent with a test that is assessed as a continuing state.
Where adult-child cases are most exposed
Set against what the page asks for, the pressure points cluster around duration, attribution and sequencing rather than any single document:
- Evidence covering only a recent window, with nothing showing how long support has been provided
- Parental funding that covers extras while the applicant's own income covers rent, food and clothing
- Transfers that cannot be linked to the applicant's basic costs, because the trail stops at an intermediate account
- Disability claims supported by general medical material that does not address the loss of function or its effect on work
- Lodgement timed after the parent has moved past the temporary stage
- Sponsorship defects, including registrable offence issues affecting the sponsor or their partner
- A paper-only, non-refundable application charge, so an incomplete pack carries the cost of refusal
None of this is a measure of a family's resources. It is a description of what the Department says it looks for, and the stronger packs tend to read as a continuous record of who pays for basics, over how long, and why that continues to be the case.
Frequently Asked Questions
Can a child over 18 still be granted a Subclass 445 visa in 2026?
Yes, if they are over 18 and financially dependent on the parent holding a Subclass 309, 820 or 445 visa, or if they meet the separate disability evidence requirement. The Department of Home Affairs page sets no upper age limit for the adult route. Health, character, sponsorship and the values statement still apply.
What evidence does Home Affairs list for financial dependency?
The page lists bank statements, money transfers and rent receipts. These need to show reliance on the parent for basic needs — food, shelter and clothing — and how long the support has been provided. No minimum transfer amount or income threshold is published on the page.
Is a medical diagnosis enough on its own for the disability route?
No. The page asks for evidence from a qualified medical practitioner that the applicant has a total or partial loss of mental or bodily function that stops them from working. The material needs to address the functional loss and its effect on the ability to work, not simply name a condition.
Does a parent paying university fees make an adult child dependent?
Payment of fees can form part of the record, but the test on the page is reliance for basic needs. Full-time study is not presented as a standalone route on the Department of Home Affairs page, so enrolment works best as context for continuing financial reliance rather than as a substitute for it.
Who can sponsor the adult child's application?
The sponsor must be the same person who sponsored or nominated the parent's permanent Partner visa application, and that sponsorship must be approved before the visa can be granted. A pending registrable offence charge affecting the sponsor or their spouse or de facto partner leads to refusal; a conviction leaves approval open only in very limited circumstances.
Does the Department look at dependency again after the application is lodged?
The Migration Regulations 1994 treat dependency as a continuing requirement assessed at the point of decision, and the Department's PAM3 guidance describes verification that nothing material has changed where dependency was assessed more than six months earlier. The current version of those instruments should be treated as authoritative, since the published eligibility criteria do not set out those steps.
What happens to the application charge if the visa is refused?
The Department states it will not refund the application fee if the application is refused. The charge also has to be paid before the paper application is posted, as processing does not begin until payment is made.
