Child support explained
Child support is a financial arrangement where one parent pays the other to help cover the costs of raising their children. This guide explains how child support works in Australia, what factors determine how much is paid, and how the process works.
What child support means in Australia
Child support is the legal obligation for a parent to financially contribute toward the cost of raising their child. In Australia, this applies to children under 18 years of age, or up to 23 in some circumstances where the child is still studying full-time. The purpose of child support is to ensure both parents share the financial responsibility for their child's wellbeing and living expenses.
The Australian Child Support Scheme is administered by the Department of Services Australia and sets out how child support is calculated and collected. The scheme recognises that children deserve financial support from both parents, regardless of custody or living arrangements.
There are generally three ways child support can be arranged. A private agreement is an arrangement made directly between parents without involving the government. Alternatively, parents can apply for an assessment through the Child Support Scheme, where the amount is calculated based on specific formulas and guidelines. Some parents choose a binding child support agreement, which is a formal arrangement that both parties agree to and can be enforced if needed.
Understanding your obligations and rights around child support is important. The child support calculation takes into account factors such as each parent's income, the percentage of time the child spends with each parent, and other relevant circumstances. Different situations may call for a change of assessment if there are significant changes in income, living arrangements, or other factors affecting the original calculation.

The Australian Child Support Scheme provides a formal way to arrange and enforce support
Income levels and care arrangements are among the matters that may be relevant in determining how much support is paid.
There are multiple ways these arrangements can generally be structured, depending on individual circumstances.
Reviews are sometimes connected to significant changes in a person's situation.
Common situations
People often find themselves considering child support in several different situations:
You've separated or divorced and have children requiring financial support
You're a sole parent receiving an income and want to formalise support arrangements
Some people are the paying parent and consider their obligations and their capacity to pay.
Your income has changed significantly and you believe your current arrangement no longer reflects your circumstances
You have a blended family with children from different relationships
Your child's living arrangements have changed, affecting the proportion of time spent with each parent
You're concerned about the fairness of the current arrangement
You want to move from an informal agreement to a formal, enforceable arrangement
When child support arrangements are unclear or informal, disputes can arise down the line. For example, disagreements about amounts paid, confusion about whether an arrangement is binding, or unexpected changes in circumstances can create tension and uncertainty. Where arrangements are not clearly documented, questions about enforcement can arise if a parent stops paying or disputes the amount owed. Many families have formal arrangements in place.
What to consider
What is your current income and how stable is it?
What percentage of time does the child spend with each parent?
Are there other financial factors (such as debt, assets, or additional children) that affect your capacity?
Is the current arrangement in writing and understood by both parties?
Have there been significant changes since the arrangement was first made?
What documentation do you have to support your agreement?
Would a formal assessment or binding agreement provide more certainty for everyone involved?
