Child support is meant to ensure that children are financially cared for after their parents separate. In Australia, child support is a legal obligation. It helps cover the costs of raising a child, such as food, housing, school supplies, clothing, and healthcare. Unfortunately, not all parents meet this responsibility. If the other parent stops paying or refuses to pay child support, it can place significant stress on both the custodial parent and the child. This article outlines what your options are if you’re in this situation and how Tonkin Law, experienced divorce lawyers in Melbourne, can help.

Understanding Child Support in Australia
Child support in Australia is governed by the Department of Human Services – Child Support (now under Services Australia). The system is designed to ensure both parents contribute to their child’s upbringing, whether they live with the child or not.
Support payments can be worked out:
- Privately: where both parents agree on an amount and schedule.
- Through a formal assessment, calculated by Services Australia based on both parents’ income, care percentage, and number of children.
When a parent stops paying, it can disrupt the child’s life and affect their access to essential needs. That’s why it’s important to act quickly and understand your rights.
Common Reasons for Non-Payment
There are several reasons why a parent may stop paying child support:
- They’ve lost their job or income has changed.
- They disagree with the amount assessed.
- They’re trying to avoid responsibility.
- They claim they can’t afford the payments.
Regardless of the reason, a parent cannot simply stop paying without going through the correct legal channels. Child support is enforceable, and failure to pay has consequences.
What You Can Do If Child Support Isn’t Paid
If the other parent stops paying, your response depends on how the payments were arranged.
If it’s a private agreement:
You may need to contact the other parent and request payment. If this doesn’t work, you can apply to Services Australia to have the child support formally collected and enforced.
If Services Australia is involved:
They have strong powers to collect overdue child support. You should notify them immediately. They can take steps such as:
- Garnishing wages directly from the employer.
- Withholding tax refunds.
- Suspending the non-paying parent’s passport.
- Taking legal action or seizing property.
Tonkin Law, leading divorce lawyers in Melbourne, often assist clients with transitioning from private agreements to formal collection methods when payments stop.
Legal Options Through the Court
In some cases, it may be necessary to take the matter to court. For example, if:
- The paying parent is hiding income or assets.
- There is a dispute over paternity.
- You want to recover a large amount of unpaid support.
You can apply to the Federal Circuit and Family Court of Australia to seek a recovery order or judgment for unpaid amounts. This process can be complex, so it’s recommended to get legal advice.
Tonkin Law can guide you through the legal steps, ensuring all documents are filed correctly and represent your interests in court if needed.
Preventing Future Payment Issues
One way to reduce the risk of future payment issues is to formalize the arrangement properly. A binding child support agreement is a legal contract signed by both parents. It outlines payment amounts and schedules and is more enforceable than informal deals.
Another option is using the Child Support Collect service, which removes the need for personal contact between parents. Services Australia will collect payments and transfer them to the receiving parent.
Tonkin Law can help draft binding agreements and ensure that your child’s financial needs are protected now and in the future.
The Impact on Children
When child support isn’t paid, the financial pressure often falls on the parent with day-to-day care. This can lead to stress, difficulty paying for basics, and reduced opportunities for the child. Unfortunately, children are the ones who suffer most when financial responsibilities aren’t met.
Keeping payments regular and fair ensures that children continue to live stable, supported lives. That’s why the law in Australia takes non-payment seriously.
Don’t Wait – Get Help Early
If you’re struggling with a non-paying co-parent, it’s important not to ignore the issue. Letting the problem drag on can create financial hardship and emotional strain. Taking early action—whether through Services Australia or the courts—helps keep things on track.
Tonkin Law, expert divorce lawyers in Melbourne, offer support and advice tailored to your situation. Their team can explain your rights, assist with collection issues, and represent you in legal proceedings if necessary.
Final Thoughts
Raising a child is a shared responsibility, even after a relationship ends. When one parent fails to pay child support, it can place an unfair burden on the other and affect the wellbeing of the child. Thankfully, there are systems in place to enforce payment and legal avenues to recover what’s owed.
