Understanding when child support stops can be confusing for separated parents. While many assume payments automatically end at 18, there are circumstances where they can continue longer, particularly if your child is still in school or has special needs. This guide explains when child support stops in Queensland, how extensions work, and what to do if your situation changes.
If you’re unsure about your obligations, our Gold Coast family lawyers can help you understand your options and know where you stand.

At What Age Does Child Support Stop in Australia?
Under the Child Support (Assessment) Act 1989 (Cth), child support generally stops when a child turns 18 or finishes secondary school, whichever happens later. The Services Australia Child Support Agency manages child support assessments and payments. This ensures both parents contribute to the cost of raising children according to their incomes and care arrangements. These assessments also take into account the level of care of the child provided by each parent and how much time a child spends in each household.
Child support payments may end earlier if:
- The child marries, enters a de facto relationship or forms a marriage-like relationship
- The child becomes financially self-sufficient.
- The child dies.
- The paying parent or receiving parent is no longer an Australian resident.
If you have a binding child support agreement, it will outline the duration and conditions for payments. However, agreements or assessments don’t continue indefinitely. They end once Services Australia determines the child is no longer eligible.
When Can Child Support Continue After 18?
In Queensland, parents or carers can apply to extend child support beyond 18 if the child is completing their final year of secondary education. This extension usually lasts until the end of the school year in which the child turns 18, provided the request is made before their 18th birthday.
Extensions are designed to ensure financial support continues until the child finishes school, helping cover ongoing costs such as books, uniforms, and transport.
In some cases, child support may also continue through an adult child maintenance order. This applies when a child:
- Has a physical or mental disability and cannot support themselves, or
- Is pursuing tertiary education and remains financially dependent.
Applications for adult child maintenance are made to the Federal Circuit and Family Court of Australia, and the court will consider the child’s needs and both parents’ financial capacity before making an order. These types of applications often arise in more complex child support matters, especially where education or disability affects a child’s independence.
What If Circumstances Change?
Family situations often evolve. You may need to update or end your child support arrangement if:
- The child’s living arrangements change, such as moving to live with the other parent or a non-parent carer entitled to receive child support.
- One parent’s income or employment status changes significantly.
- The child stops full-time study or becomes self-sufficient, or another relevant dependent child enters your household
You can request a re-assessment through Services Australia to reflect the new circumstances. Continuing to pay or receive child support under outdated conditions can create overpayments or arrears, so it’s important to review your assessment whenever there’s a major change in care or income.
What Happens If You Stop Paying Child Support Too Soon?
If you stop paying child support before your assessment or agreement officially ends, arrears can quickly build up. Services Australia can recover unpaid amounts through:
- Deductions from wages or tax refunds.
- Legal recovery action.
- Suspension of licences or travel restrictions in serious cases.
Even if you believe your child is no longer dependent, it’s vital to confirm the official end date with Services Australia before stopping payments. Ending payments without approval may breach your legal obligations and result in enforcement action.
If you believe your assessment should end, contact the Child Support Agency or your family lawyer to confirm eligibility and request a review.
Can Parents Agree to End Payments Early?
Parents sometimes agree to end child support early when the child becomes independent or starts full-time work. However, private arrangements only take effect if they comply with legislation and are accepted by Services Australia.
If you have a limited or binding child support agreement, both parties must agree to vary or terminate it, and it must meet formal requirements before being accepted. Simply deciding between yourselves to stop payments doesn’t override an active assessment or court order.
To avoid disputes, always:
- Get any change formally documented.
- Confirm Services Australia has accepted the variation.
- Seek legal advice before finalising the change.
How to End or Update Child Support Payments
If your child is nearing 18 or finishing school, it’s important to plan ahead. The process for ending or updating payments typically involves:
- Confirming the child’s age and education status through Services Australia.
- Contacting the Child Support Agency to request an end date or extension.
- Providing evidence, such as school enrolment details, if an extension is needed.
- Applying for adult child maintenance if the child remains dependent due to study or disability.
- Seeking legal advice to understand your rights under a binding child support agreement or court order.

When to Get Legal Advice
Child support laws are designed to be fair, but every family’s situation is different. You should seek legal advice if:
- There’s disagreement about whether payments should end or continue.
- The other parent refuses to cooperate or disclose income.
- You’re unsure whether your child support agreement remains valid.
- You need help applying for or responding to an adult child maintenance claim.
