How is child support worked out in Australia?

Common question · Family Law · Australia · 23 October 2026

General information from Lawmateanz

Child support in Australia is usually assessed by Services Australia using a formula that considers both parents' incomes, the care each provides, and the children's ages.

Parents can also make a private arrangement or a child support agreement.

If the assessment doesn't reflect your circumstances, you can ask for a change of assessment, or object to a decision.

Services Australia's estimator gives an idea of what may be payable.
