Does My Child Need to Be Under 18 for the Subclass 102 Adoption Visa in 2026?
Explains whether an adopted child must be under 18 at adoption, application and decision for Australia's Subclass 102 visa in 2026.
Yes. For the Adoption visa (Subclass 102), the child must be under 18 at three separate points in time: when they were adopted, when the application is submitted, and when the Department of Home Affairs decides it. That is what the Department of Home Affairs sets out on its official "Adoption visa (Subclass 102)" page, as at the August 2026 official page.
This matters more than it first appears, because the third test is the one families tend to overlook. A child who is comfortably under 18 on the day you lodge can still fall outside the criteria if the decision lands after their eighteenth birthday. The subclass 102 adoption visa age limit under 18 2026 is therefore not a single checkpoint — it is a condition that has to hold across the whole life of the case.
What exactly does the under-18 rule cover?
The department states the child must "have been under 18 years of age when adopted, when they apply and when we decide". Broken into the sequence a family actually experiences it:
| Point in time | What must be true |
|---|---|
| When the adoption happened (or happens) | The child was under 18 |
| When the application is submitted | The child is under 18, and outside Australia |
| When the department decides the application | The child is still under 18, and still outside Australia |
Two further requirements travel alongside the age test. The child must be outside Australia both when the application is made and when it is decided, and must be adopted — or in the process of being adopted — by the sponsoring parent. Failing one of these is as decisive as failing the age test.
Does "when adopted" mean the same thing in every case?
Not always, because not every family arrives at the visa with a completed adoption. The official criteria allow an application where the child has already been adopted, or — for an intercountry adoption arranged with an Australian state or territory central authority, or an intercountry adoption between two other countries that are parties to the Hague Adoption Convention — is in the process of being adopted. An expatriate adoption, where no Australian state or territory central authority is involved, is covered only where the adoption has already taken place.
Where the adoption is already finalised, "when adopted" points to a date in the past that can be read off the adoption record. Where the adoption is still progressing at the time you lodge, the phrase refers to the date the adoption is finalised. In other words, the clock does not stop at lodgement for a prospective adoption — it keeps running to the adoption itself and then to the decision.
Assume an applicant whose adoption order records a finalisation date after the child's eighteenth birthday. On the face of that document, the "when adopted" limb is not met, regardless of how young the child was when the paperwork was first lodged.
What happens if the child turns 18 while the application is pending?
The decision-time requirement is the one that bites here. The child must be under 18 at the moment the department makes its decision, and there is no provision on the subclass 102 page that preserves eligibility for a child who has already turned 18 by then. Age is assessed as a fact at each of the three points, not frozen at the date of lodgement.
That is the whole reason the "should we rush to lodge?" question is worth thinking about properly rather than emotionally.
If my child is close to 18, is lodging quickly the answer?
Lodging before the birthday is necessary but not sufficient. It secures the application-time test only. If the case is still undecided on the eighteenth birthday, the decision-time test fails — so the useful question is not "can we lodge before the birthday?" but "can this application be decision-ready before the birthday?"
Things that fall within an applicant's control and affect that timing include:
- whether the sponsorship has been submitted and can be assessed — the department must approve the sponsorship before the visa can be granted
- whether health assessments are done early — the child, and any dependent child applying with them, must meet the health requirement
- whether the adoption evidence is complete at lodgement, including proof that the adoption follows the law of the child's country of residence
- whether the child's age brings in the character requirement, which applies once they are 16 or older
The practical reading is that a thin, hastily lodged application does not protect a child who is about to turn 18; a complete one has a better chance of being decided inside the window. This is general information about how the published criteria fit together, not advice on any particular family's circumstances, and where timing is this tight it is worth checking the current wording on the official page or getting advice from a qualified professional before you commit to a plan.
Does anything else change as the child gets older?
Two age-linked criteria appear in the criteria beyond the under-18 test itself. The character requirement applies if the child is aged 16 or over, so the older the child at assessment, the more the case resembles an adult application in that respect. Separately, the department may refuse the visa if granting it would not be in the best interests of an applicant under 18 — a consideration that applies to every applicant in this visa because all of them are, by definition, children.
For expatriate adoptions there is also a residence condition on the parents rather than the child: at least one adoptive parent must have resided outside Australia for more than 12 months immediately before the application is lodged, must not have resided overseas in order to avoid Australia's intercountry adoption laws, must hold full and permanent parental rights, and the adoption must comply with the adoption laws of the home country. The department also notes that a legal adoption overseas does not automatically satisfy the subclass 102 requirements, and that it has no role in overseas expatriate adoptions — it only assesses and decides the visa.
Frequently Asked Questions
Does my child have to be under 18 at all three points, or only when we apply?
All three. The Department of Home Affairs requires the child to have been under 18 when adopted, when the application is submitted, and when the decision is made. Missing any one of the three means the age criterion is not met.
If we lodge the day before my child's 18th birthday, is the age requirement locked in?
No. Lodging before the birthday satisfies the application-time test only; the child must still be under 18 when the department decides. A decision made after the eighteenth birthday leaves the decision-time test unmet.
Is the age rule different for Hague Convention adoptions?
The official criteria apply the same under-18 test regardless of pathway, whether the adoption is arranged through an Australian state or territory central authority, under the Hague Adoption Convention, or as an expatriate adoption. What differs between pathways is the adoption and residence evidence, not the age limit.
Does the child also need to be outside Australia?
Yes. The child must be outside Australia when the application is made and when it is decided, in addition to meeting the age requirement at adoption, application and decision.
My child is 16 — does that change the assessment?
The character requirement applies to applicants aged 16 or older, so a 16- or 17-year-old is assessed on character as well as health, sponsorship and the other criteria. The under-18 requirement still applies in exactly the same way.
What if the adoption is not finalised yet?
The criteria allow an application where the child is in the process of being adopted, but the child must still be under 18 when the adoption is finalised, when the application is submitted and when the decision is made. A proposed adoption that completes after the child turns 18 does not satisfy the "when adopted" limb.
