In Australia, you generally stop paying child support when your child turns 18, but payments can extend if they're in full-time secondary school (until the end of that school year/term) or if a court orders "adult child maintenance" for tertiary study or disability. Early termination can also occur if the child marries, becomes de facto, or becomes financially independent.
Normally child support stops when your child turns 18. If your child's in secondary study, you can apply to extend it to the end of the school year.
Child support is payable for all children living in Australia whose parents have separated, whether or not the parents were married to each other. If a child turns 18 during their last year at school then that child is eligible for child support until they complete the school year.
If a child under the age of 18 leaves school, starts full-time employment or becomes financially self-sufficient, you may be able to stop paying child support. However, this is not automatic. You will need to contact Services Australia and may need to request a formal reassessment of your obligations.
In Australia, child support obligations generally cease when the child turns 18, unless they are still in secondary education, in which case support may continue until the end of the school year.
How long do I have to pay child support? The legal duty of support continues until the child turns 18 years of age, and has graduated from high school; or turns 19 years old, whichever occurs first; marries; dies; or is legally free in some way, such as joining the military.
No, a father generally cannot simply refuse to pay child support in Australia; it's a legal obligation, and failing to pay leads to serious enforcement actions like wage deductions, tax refund intercepts, asset seizure, or even travel bans by Services Australia. While you can apply for reassessments or payment plans if you genuinely can't pay, refusing payment will result in the government taking action to recover the debt.
As a result, the amount of child support payable may increase to accommodate these additional needs. Key takeaway: Child support payments may rise when a child turns 13 due to the higher cost bracket applied by the child support formula.
Minimum child support payments vary by country, but in Australia, it's a set annual amount for parents with low income or limited care, with the rate increasing yearly (e.g., around $534 annually as of early 2025) and a fixed rate for some parents; however, these minimums generally don't apply if you have regular care (over 52 nights) or a private agreement. The actual minimum is determined by your income and care arrangements, with the goal of ensuring all parents contribute, and can be adjusted if you can prove your income is genuinely low.
Financial support provided for a child over the age of 18 by a parent (or in some rare cases, a step-parent) is called adult child maintenance. This is different from child support, which is provided for children under the age of 18. Adult child maintenance payments can be made periodically or as a lump sum.
Starting from January 1, 2023, if the combined income of the parties exceeds $206,310, the maximum child support amount to be divided between them for children aged 12 years and below is as follows: $25,169 for one child. $39,198 for two children. $49,515 for three children.
Standard Backdating Periods:

If your ex-partner has more children, Services Australia will adjust the child support assessment to reflect their new responsibilities. This may lower the payments you receive, but their obligation to support your child does not end.
The biggest mistake in a custody battle is losing sight of the child's best interests by prioritizing parental conflict, anger, or revenge, which courts view very negatively. This often manifests as bad-mouthing the other parent, alienating the child, refusing to cooperate, or involving the child in disputes, all of which signal poor co-parenting and harm the case.
Because the formula is based on each parent's adjusted taxable income, a means to lawfully reduce payments is to reduce taxable income by strategies such as:
In state-by-state rankings, Massachusetts ranks highest with the most expensive child support payments, averaging $1,187 per month. Virginia mandates the least support at $402 per month.
Child support is an essential aspect of family law, designed to ensure that children receive financial support from both parents, even in cases of divorce or separation. In California, as in most states, child support typically ends when the child reaches the age of 18.
If the child is working full-time or is considered to be financially independent based on their income amount, then it is possible that child support payments may no longer be required.
Child support is only calculated based on the two parents' incomes and does not include new spouses or partners.
In Australia, your $100k income means you'll pay child support based on a formula involving both parents' incomes, the number/ages of children, and care arrangements, typically using the Child Support Estimator on Services Australia's website. For a combined income around $100k, your payment will likely involve a base amount plus a percentage of income over a threshold (e.g., $14,324 + 12c for income over $89,523 for one child), but it's complex and depends heavily on the other parent's income and care time.
If a parent refuses to make payment and the debt accrues then the Child Support Agency has the following powers: Make the liable parent's employer deduct amounts from their pay. Intercept and use a tax refund to meet an outstanding child support payment. Deduct lump sums from a liable parent's bank account.
If you have a child support debt we may issue a Departure Prohibition Order. It'll stop you from leaving Australia until you either: pay your debt in full. enter into an acceptable payment arrangement.
That said, you can receive payments once your child is 18, but it depends on your circumstances. In most cases, child support stops, but if your child is in secondary school, you can apply to extend it to the end of the school year.
Additionally, assets may be seized and sold to cover the debt. Non-payment can also result in legal penalties, including fines or imprisonment. In extreme cases, a departure prohibition order can prevent the non-paying parent from leaving Australia until the debt is paid.
