Child support explained

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.

Key points

• Child support is the legal responsibility of both parents to contribute financially toward their child's living costs

• The Australian Child Support Scheme provides a formal way to arrange and enforce support

• Income levels and care arrangements are key factors in determining how much support is paid

• There are multiple ways to structure these arrangements, depending on your circumstances

• Regular reviews may be needed if your situation changes significantly

Common situations

You may find yourself needing to understand 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

• You're the paying parent and need to understand your obligations and assess your 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. Without a clear, documented arrangement, enforcing support may become difficult if a parent stops paying or disputes the amount owed. This is why many families benefit from formalising their arrangements.

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?
