Partner and dependent children on a 866 Protection application in 2026
Your spouse or de facto partner, and your dependent children or step-children, can be included on the same Protection visa (subclass 866) application as you — provided each of them is in Australia when you apply and is themselves eligible for the visa. That is the position set out on the Australian Department of Home Affairs Protection visa (Subclass 866) official page. This article is general information only and is not personalised advice about your family's circumstances; the definitions on the official page, and a qualified professional's view on your specific situation, are what should govern your decisions.
Who can be included on the same subclass 866 application?
The official page uses the term "members of the same family unit." Members of the same family unit may apply together on the same application, and they must be in Australia at the time of application and be eligible to apply for this visa.
Members of the same family unit are the spouse or de facto partner of the family head, a dependent child or step-child of the family head, a dependent child or step-child of the family head's partner, and other dependent relatives of the family head. For this visa, family reunion therefore works through one application rather than separate partner or child applications — but only for people who fit one of those categories and are onshore.
Does a de facto partner count the same as a spouse?
Yes. The page places "spouse or de facto partner of the family head" in the same bullet, with no separate or lesser test stated for de facto partners. A partner relationship short of marriage is not treated as a different, weaker category for the purpose of deciding who belongs to the family unit.
The same cut-off applies in the other direction, though: a child or step-child of any age is not considered a dependent child if they are currently married, engaged to be married, or in a de facto relationship. A child who is themselves in a de facto relationship is not considered a dependent child and, as a child who is not a dependent child, must apply for their own visa.
What makes a child a dependent child here?
A dependent child is a child or step-child who is under 18 years old. That is the whole test for most families — age alone does the work.
A dependent child can also be 18 years old or older, but only on one of two grounds stated on the official page:
- they are incapacitated for work due to loss of their bodily or mental functions; or
- they are wholly or substantially reliant on their parent or step-parent for financial, psychological or physical support.
Note how broad the second limb is. Reliance is not limited to money; psychological and physical support are expressly included, and the standard is "wholly or substantially," not exclusively.
When does an adult child stop counting?
There are two ways an older child falls outside the definition. The first is independence: if an adult child is not incapacitated for work and is not wholly or substantially reliant on the parent or step-parent for financial, psychological or physical support, the reliance limb is not met.
The second is relationship status, and it is absolute. The Department does not consider a child or step-child of any age to be a dependent child if they are currently married, engaged to be married, or in a de facto relationship. "Of any age" matters: this overrides the age and reliance tests entirely, so a 17-year-old who is married is not a dependent child for this visa.
Children who are not dependent children must apply for their own visa. They are not simply left off your application — they need a separate visa pathway of their own.
Do step-children and my partner's children count?
Both are covered, and the page lists them separately from each other. A dependent child or step-child of the family head is included, and so is a dependent child or step-child of the family head's partner.
That second limb is easy to miss. It means a child can be brought into the family unit through your partner's relationship to that child rather than through yours — relevant where you and your partner have children from previous relationships, or where a step-child's other biological parent is not part of the application. The child still has to meet the dependent child test, including the age, reliance and relationship-status rules above.
Who is the family head, and why does it matter?
The family head can be you, or it can be someone else in your family who has not applied for this visa. The official page is explicit that the family head can be someone else in your family who has not applied for this visa.
This matters because the categories are defined by reference to the family head. Suppose the family head is your partner rather than you, and your partner has not applied for this visa: your relationship to the family unit runs through being their spouse or de facto partner, and your children enter as dependent children or step-children of the family head or of the family head's partner. Working out who the family head is should happen before you decide who goes on the form.
What does the dependency test actually ask?
For children, the question is whether a child over 18 relies wholly or substantially on a parent or step-parent for financial, psychological or physical support — or is incapacitated for work because of lost bodily or mental functions. For other dependent relatives, the test is stricter: the relative must not have a spouse or de facto partner, must usually live with the family head, and must be wholly or substantially reliant on the family head for financial, psychological or physical support.
The differences are worth noting. A child's reliance is measured against a parent or step-parent, while another relative's reliance is measured against the family head specifically. The "no spouse or de facto partner" and "usually lives with" conditions apply to other relatives; the official page does not attach those two conditions to the dependent child test.
Because the tests are definitional, it helps to think about what element each part of your evidence is addressing: the existence of the relationship, the living arrangements, and the nature and extent of reliance. The official page states the tests rather than a document checklist, so treat any list of documents you see elsewhere as indicative only and confirm current expectations on the official page.
Does everyone have to be in Australia when I apply?
Yes, for the people you want on the same application. Members of the same family unit applying together must be in Australia at the time of application, and the visa itself must be applied for from inside Australia.
If a partner or child is outside Australia, they cannot simply be added to your subclass 866 application. The official page notes that holders of this visa can sponsor eligible family members for permanent residence through the offshore Humanitarian Program — a separate process, and one that follows the grant of a visa rather than running alongside it.
What else must each family member satisfy?
Members of the same family unit applying for this visa must meet the Department's health, character and security requirements. These are assessed person by person, so an outcome is not shared across the family: each included partner and child has to clear the same requirements as the main applicant.
The visa itself is permanent. Holders can live, work and study in Australia permanently, access government services such as Medicare and Centrelink services, and travel to and from Australia for five years from the date of grant, after which a Resident Return visa is needed to re-enter.
What happens if a child is born while the application is pending?
If a child is born after you submit your application and before a decision is made, the child is taken to be included in that application. You must tell the Department as soon as possible by completing Form 1022 Notification of change of circumstances, providing a clear colour copy of their original birth certificate, and attaching them in ImmiAccount or sending them by post to the address where you sent your application — a certified copy is required if you send it by post.
A child born in Australia is automatically granted the same visas their parents hold at the time of the child's birth. If either parent is an Australian citizen or Australian permanent resident at the time of the birth, the child might be an Australian citizen by birth.
Does travel condition 8559 apply to the whole family?
It applies to the family unit, not just the main applicant. Travel condition 8559 provides that the visa holder and members of their same family unit must not enter the country or countries from which protection was granted, unless the Department approves that entry in writing before travel.
Approval is given only where there are compassionate or compelling circumstances justifying the travel. Entering without written approval, even briefly, breaches condition 8559, and the consequence can be cancellation of your visa and the visas of members of your family unit. The page also recommends not using the passport or travel document issued by your country of nationality, because doing so may lead the Department to consider that you are no longer in need of protection.
Frequently Asked Questions
Can my de facto partner be included if we are not married?
Yes. The official page lists "spouse or de facto partner of the family head" as one category of family unit member, without distinguishing between married and unmarried partners. Your partner must still be in Australia at the time of application and meet the visa's eligibility, health, character and security requirements.
Can my 20-year-old child be included on my 866 application?
Only if they meet one of the two grounds for a dependent child over 18. They must be incapacitated for work due to loss of their bodily or mental functions, or be wholly or substantially reliant on you or their step-parent for financial, psychological or physical support. Otherwise they are not a dependent child and must apply for their own visa.
My daughter is engaged to be married — does that change anything?
Yes. The Department does not consider a child or step-child of any age to be a dependent child if they are currently married, engaged to be married, or in a de facto relationship. This applies regardless of age, so it overrides both the under-18 rule and the reliance test.
Can I include my partner's child from a previous relationship?
Potentially, yes. The family unit includes a dependent child or step-child of the family head's partner, not only of the family head. The child must still satisfy the dependent child definition, and must be in Australia when the application is made.
Is my newborn automatically part of my 866 application?
A child born after you submit your application and before a decision is made is taken to be included in that application. You must notify the Department as soon as possible using Form 1022, with a clear colour copy of the birth certificate, submitted through ImmiAccount or by post to where you lodged your application.
Do my partner and children need to be in Australia to apply with me?
Yes. Members of the same family unit applying together on a subclass 866 application must be in Australia at the time of application. Family members who are outside Australia cannot be added to that application, though the visa allows holders to sponsor eligible family members for permanent residence through the offshore Humanitarian Program.
Does my family have to meet health and character requirements too?
Yes. Members of the same family unit applying for this visa must meet the Department's health, character and security requirements. Each person is assessed individually, so one family member's outcome does not determine another's.
