Who administers child support in Australia?
Child support in Australia is administered by Services Australia through the Child Support program. Services Australia calculates the assessment, collects payments, and transfers them between parents. The scheme is established under the Child Support (Assessment) Act 1989 and the Child Support (Registration and Collection) Act 1988.
How do I apply for child support in Australia?
You can apply online through myGov at my.gov.au by linking your Services Australia account. You will need the other parent's details and information about your children. The application is free and does not require a lawyer. Services Australia will contact the other parent and issue an administrative assessment.
How is child support calculated in Australia?
Services Australia uses a formula based on both parents' taxable incomes, the number of children, the costs of raising children, and the percentage of care each parent provides. The formula is set out in the Child Support (Assessment) Act 1989 and applies automatically. You can estimate your assessment using the child support estimator at servicesaustralia.gov.au.
What if I cannot locate the other parent to apply for child support?
Services Australia can assist in locating the other parent using government databases including records held by the Australian Taxation Office and the Department of Home Affairs. You do not need to know the other parent's address to start your application.

Can parents make their own child support agreement instead of using the formula?
Yes. Parents can enter into a Binding Child Support Agreement or a Limited Child Support Agreement. A Binding Agreement must be signed with independent legal advice for each party and overrides the administrative formula entirely. A Limited Agreement requires an existing assessment and must be for at least the formula amount. Both are registered with Services Australia.
What if I disagree with the child support assessment in Australia?
You can apply to Services Australia for a Change of Assessment in special circumstances if the formula amount is unfair given your particular circumstances. There are 10 grounds listed in the legislation. If you are still dissatisfied, you can appeal to the Administrative Review Tribunal (ART). You can also apply to the FCFCOA for a court order.
Does the amount of time I spend with my child affect child support in Australia?
Yes. The percentage of care each parent provides significantly affects the child support assessment. Care is measured in nights per year. The more nights a child spends with the paying parent, the lower their child support liability. Services Australia will adjust the assessment if care arrangements change.

What happens if the other parent does not pay child support in Australia?
If a parent does not pay a Services Australia child support assessment, Services Australia has strong enforcement powers including deducting payments from wages or tax refunds, intercepting tax refunds, and referring debts to the Australian Taxation Office. You can also apply to the FCFCOA for a court order to enforce payment.
Is child support tax deductible or assessable income in Australia?
Child support payments are not tax deductible for the paying parent and are not assessable income for the receiving parent under Australian tax law. They are treated as private transfers between parents for the benefit of children.
