Evidence that proves the balance of family test for Australian parent visas (2026)

To prove the balance of family test, the Australian Department of Home Affairs asks for three things and nothing else at the evidence level: documents showing how you are related to each child, documents showing each child's Australian citizenship or country of permanent residence, and documents showing that a particular child should not be counted at all. That three-part request appears in the "gather your documents" section of the official Contributory Parent visa (Subclass 143) page, which links to the separate balance of family test explanation published for the Parent visa (Subclass 103). The underlying requirement sits in the Migration Regulations 1994, where clause 143.213 makes satisfaction of the test a criterion for applicants who are not Subclass 173 holders or holders of a substituted Subclass 600 visa.

What you have to prove before you collect a single document

Evidence only makes sense once you know which fact it supports. The Home Affairs official page states the test as two alternative limbs, and you pass if either one is true:

at least half of your children and step-children are eligible children, or
there are more eligible children living in Australia than in any other single country.

Two features of that wording drive the paperwork. First, the second limb is a comparison against each single other country, not against "everywhere else" combined; three children in one overseas country can outweigh two children in Australia, even if you have five children abroad in total. Second, the count is expressed per child and step-child, not per migrating child, which is why the document request is written as "each child."

Which documents show how you are related to each child?

This is the first of the three categories, and it exists because "child" is a legal relationship, not a statement you make in a form. The same visa page lists birth or marriage certificates as evidence of relationship for dependants, and lists change-of-name documents from an Australian Registry of Births, Deaths and Marriages or the relevant overseas authority among the identity documents for an applicant who has changed name. Those examples appear in the identity and dependant sections of the page rather than in the balance-of-family paragraph itself.

The practical test for this group is traceability: every child named in your application should have a document that connects them to you by name, and every name mismatch should be bridged by a document that explains it.

Which documents show each child's Australian citizenship or permanent residence?

The official wording is "evidence of each child's Australian citizenship or country of permanent residence."

Treat this group as covering every child, not only the children you rely on as eligible children.

Evidence group	What it establishes	Typical source documents
Relationship to each child	That the person counted is your child or step-child	Birth or marriage certificate; change-of-name records where names differ
Australian citizenship or country of permanent residence	The Australian side of the count, and each other country in the comparison	Citizenship evidence for Australian children; permanent residence evidence for children settled elsewhere
Exclusion from the count	That a child should not be counted at all	Documentary proof of the ground relied on, such as a death certificate

What proves that a child should be excluded from the count?

The third category covers children who should not appear in either limb. The Department's example is explicit: a death certificate is given as evidence that a child should not be included in the balance of family test. The general shape of the category is therefore a document that establishes the exclusion ground itself, rather than a statement that you would prefer the child not to be counted.

This group matters most in borderline families. Removing one child from the denominator can move an application across the "at least half" threshold, so the exclusion needs to be supported by a document.

How do the three groups work together in one family?

Assume — purely as an illustration of how the rules combine — an applicant with four children and step-children: two Australian citizens living in Australia, one permanently resident in New Zealand, and one who has died. Applying the official wording, the relationship documents establish all four links, the citizenship and permanent residence documents establish the Australian side and the New Zealand side, and the death certificate removes the fourth child from the count. The result, if those two children are eligible children, is two out of three counted children being eligible children. Strip out the death certificate and the same family becomes two out of four, which still satisfies the first limb because "at least half" includes exactly half — but the margin disappears, and any further gap in the file would drop the family below the threshold.

The point of the example is the arithmetic: each child you cannot document either stays in the count without being established as an eligible child or cannot be placed in the comparison.

Where do balance-of-family files fall short in practice?

Four gaps recur, and none of them require new documents — only complete ones.

Covering only the Australian children. The comparison limb cannot be assessed without the residence position of every child who is not counted as eligible.
Treating step-children separately. The first limb expressly counts children and step-children, so ignoring that phrase changes the denominator.
Unexplained name differences. A name mismatch across a birth certificate and a citizenship record is a traceability problem, solved with the change-of-name documents the Department already lists.
Details gathered for migrating members only. The application requires details of all family members even if they are not migrating.

This article is general information about how the published requirements work; it is not personalised advice on your circumstances. No outcome can be promised on any particular set of documents.

Who does not need these documents at all?

If you hold a Contributory Parent (Temporary) (Subclass 173) visa when you apply, you have already met the balance of family test. You will not need some of the documents usually requested if you hold the Subclass 173 visa when you apply, or if it ended in the 28 days immediately before you apply. Separately, if more than 28 days have passed since your Subclass 173 visa ended, you can apply under the two-stage pathway if you provide evidence of compelling and compassionate circumstances and the Minister is satisfied they exist. You must still supply documents letting the Department know you are getting help with your application, and about any change in your situation since the 173 grant.

Applicants using the retiree pathway do not need to meet the test. That pathway requires that on 8 May 2018 you held or had previously held an Investor Retirement (Subclass 405) or Retirement (Subclass 410) visa, that you have not held another substantive visa between that date and the date you apply, and that you are in Australia; those applicants do not need the balance of family test, a sponsor, or an Assurance of Support, but they are personally liable for their healthcare costs while the visa is processed and must maintain adequate health insurance until grant.

Frequently Asked Questions

What documents does the Department ask for to prove the balance of family test?

Home Affairs asks for three categories: evidence of how you are related to each child, evidence of each child's Australian citizenship or country of permanent residence, and evidence that a child should not be included in the test. The request is framed per child, so it applies to every child rather than only to those migrating.

Do I need documents for children who are not coming to Australia?

Yes, because the application requires details of all family members even where relatives are not migrating.

Does a step-child count, and how is that proved?

The official statement of the first limb refers to "children and step-children," so step-children are inside the count.

My child lives outside Australia — what should I show?

The page asks for evidence of each child's Australian citizenship or "country of permanent residence." For a child settled overseas, that means documents establishing the country in which they hold permanent residence, so the comparison against Australia can actually be made.

When can a child be excluded from the test?

Exclusion applies where a child should not be counted at all, and the Department gives a death certificate as its example of the evidence needed. The general principle is that you document the ground for exclusion rather than simply omitting the child.

Do I still need this evidence if I hold a Subclass 173 visa?

No, not for the test itself. According to the official page, Subclass 173 holders have already met the balance of family test, and some usually required documents are not needed, although evidence is still required to let the Department know you are getting help with your application, and for changes in your situation since the 173 visa was granted.

What happens if I cannot prove my own identity?

The consequences go beyond this test: if you cannot prove your identity, the Department states it will refuse the visa application, and it might not grant another visa to you for 10 years or to family members listed on the application.

Do cost or lodgement rules change the evidence?

They change how and when you send it, not what proves the test. Applications made on or after 22 April 2026 must be lodged online using ImmiAccount, where documents are attached electronically.
