Child support can feel like a minefield of questions after separation. What does child support cover? Who decides how much? And what happens if one parent refuses to contribute to private school fees or medical bills? In NSW, as in the rest of Australia, child support follows federal law, meaning the rules are consistent nationwide. This guide explains exactly what child support covers, how payments are calculated, and what your options are if you and your co-parent cannot agree.
What Does Child Support Cover?
Child support is a legal obligation requiring both parents to financially contribute to their child’s expenses after separation or divorce, regardless of their relationship status or whether they are involved in their child’s day-to-day life.
Payments are intended solely for the benefit of the child. They are not a subsidy for the receiving parent’s personal expenses. At its core, child support is designed to ensure that children maintain a reasonable standard of living across both households following the breakdown of their parents’ relationship.
Child support can cover a wide range of expenses, including:
- Housing costs such as rent, mortgage contributions, and utilities
- Food and everyday nutrition
- Clothing appropriate to the season and the child’s stage of life
- Transport to and from school, childcare, and medical appointments
- Public school fees, uniforms, textbooks, and school supplies
- Routine healthcare, including GP visits, vaccinations, and basic dental care

Things to Know About Child Support
The Primary Caretaker
The parent who has the child living with them most of the time is known as the primary caretaker. They typically receive child support payments, which they can use to cover the variety of the child’s expenses listed above. The non-custodial parent, meaning the parent the child does not primarily live with, pays child support even if they have regular visitation rights.
Importantly, not having parental responsibility does not excuse a parent from their child support obligations.
Common Misconceptions
While fathers are statistically more likely to be the paying parent, this is not always the case. Many mothers also pay child support. Similarly, a non-custodial parent may remain very actively involved in their child’s life while still being required to make payments. Child support is not based on the parents’ marital status, meaning de facto couples who separate are subject to the same rules as divorced married couples.
Child support payments are used exclusively for the care of the child, not for the custodial parent’s personal benefit. Whatever the circumstances, the goal is for parents to share financial responsibility for raising their children equitably.
What Child Support Covers in NSW: All the Expenses Explained
1. Basic Necessities
The foundation of any child support assessment covers food, clothing, and shelter. These are the non-negotiable baseline expenses that every child needs to thrive. This includes nutritious meals, weather-appropriate clothing, and a safe, stable home environment.
In some cases, child support may also extend to reasonable entertainment and leisure costs such as internet access, a family computer, or visits to parks and recreational facilities. Whether these are included will depend on the parents’ combined income and the specific circumstances of the child.
2. Medical Expenses and Uninsured Medical Costs
Most child support assessments contribute to a child’s healthcare costs. The parent with access to better employer-covered benefits is typically required to maintain medical, dental, and optical coverage for the child. Does child support cover medical bills? is one of the most common questions parents ask, and the short answer is yes, for routine costs.
For extraordinary or uninsured medical expenses, the situation is more nuanced. Out-of-pocket costs that exceed basic health insurance coverage can include:
- Co-payments and excess fees
- Orthodontic treatment, such as dental braces
- Surgery
- Casts and physiotherapy
- Prescription eyeglasses
- Specialist or allied health therapies
For example, a child requiring orthodontic braces at an out-of-pocket cost of $5,000 to $8,000 is a common and often heated point of dispute. In these cases, parents can apply to Services Australia for a variation to the standard assessment to account for the extraordinary cost.
3. School Fees and Education Expenses
All children have the right to a proper education, and child support is designed to help fund it. For children attending public schools, child support covers a range of education-related costs:
- School uniforms and clothing
- Tuition or school fees
- Textbooks and stationery
- Lunch money
- Travel expenses to and from school
- Private tutoring where necessary
- Extracurricular activities (when agreed by both parents)
Private school fees are a different matter. They are not automatically included in a standard child support assessment. Whether private school fees are covered depends on whether both parents agreed to private schooling before separation, whether the child was already attending that school, and whether there is a specific agreement or court order in place.
4. Childcare
When neither parent can provide care due to work obligations, child support can contribute to the cost of daycare, babysitters, or nannies. Both parents may need to share these costs, particularly when unexpected business commitments arise.
5. What Child Support Does NOT Automatically Cover
This is the question most parents actually want answered. Standard child support assessments do not automatically include:
- Private school fees (unless agreed or ordered by a court)
- Extracurricular activities such as sports, music lessons, or dance
- International school trips or optional excursions
- Luxury clothing or non-essential items
- High-end entertainment or holidays
If you want child support to extend to these areas, this must be formalised through a Binding Child Support Agreement or addressed through a variation application to Services Australia. Some of these costs, such as agreed private school fees or health insurance premiums paid directly to the provider, may be credited towards a parent’s child support obligations as prescribed expenses, up to 30% of the annual assessment amount.
How Is Child Support Calculated in NSW?
Services Australia uses an 8-step formula to determine how much each parent pays. The key factors are:
- Each parent’s adjusted taxable income, minus a self-support amount (set at $31,046 in 2026)
- The combined parental income
- The number of children
- The percentage of care each parent provides
- The costs of raising children at that combined income level
The result is a formal assessment letter that sets out the exact amount payable. The minimum annual rate is $534 for low-income parents, while higher-income families may pay significantly more. Payments are generally made until a child turns 18 years of age.

Child Support Agreement Options
Separated parents are not limited to the standard Services Australia assessment. Private agreements allow both parents to tailor payments to their family’s specific needs, providing greater stability for the child.
| Binding Child Support Agreement | Limited Child Support Agreement | |
|---|---|---|
| What it is | A private arrangement specifying payment details, including regular payments, lump-sum contributions, or direct payments to third parties such as a school or insurer | A written arrangement covering monetary support and other forms of assistance such as health insurance or school fees |
| Legal advice required | Yes, independent legal advice is mandatory before signing | No legal advice required |
| Duration | No fixed expiry unless specified | Valid for up to three years |
| Best suited for | Long-term, complex arrangements | Shorter-term or simpler agreements |
Child support agreements are best recorded in writing to avoid miscommunication or disputes down the track. Payments made directly by the paying parent to a third party, such as directly to a school or health insurer, can count towards child support obligations with mutual agreement. Child support amounts can also be altered if there are special circumstances, such as large unforeseen medical expenses.
Adult Child Maintenance
Child support typically ceases when a child turns 18. However, a parent, legal guardian, or the child themselves can apply to the court for adult child maintenance if the child:
- Has a serious mental or physical disability
- Is completing secondary or tertiary studies
- Is experiencing a serious illness
If both parents agree to continued maintenance, or if the child and paying parent consent, the court can formalise this as an adult child maintenance order. An application can be made when the child is 17 or after they turn 18.

Frequently Asked Questions
Does child support cover private school fees in NSW?
No, private school fees are not automatically included in a standard child support assessment. To include them, both parents must enter into a formal agreement, or one parent can apply to Services Australia for a variation to the standard assessment based on special circumstances.
Does child support cover extracurricular activities?
Not automatically. Extracurricular activities such as sport, music lessons, or dance classes are considered non-essential costs and are excluded from the standard formula. Parents who want these costs shared should formalise the arrangement in a Binding or Limited Child Support Agreement.
What does child support NOT cover?
Child support does not automatically cover private school fees, extracurricular activities, luxury goods, holidays, or high medical expenses beyond the routine level. These costs require either a separate agreement between the parents or a variation application to Services Australia.
Can I pay child support directly to the school or doctor instead of to my co-parent?
Yes. Payments made directly to a third party such as a school or health insurer can be counted towards your child support obligations, provided both parents have agreed to this arrangement. These are called prescribed expenses and can be credited up to 30% of the annual assessment amount.
When does child support stop in Australia?
Child support generally stops when a child turns 18. It may continue beyond that if the child has a serious disability, is completing secondary or tertiary education, or is experiencing a serious illness, in which case a court can issue an adult child maintenance order.
How does Services Australia calculate child support payments?
Services Australia uses an 8-step formula that takes into account each parent’s adjusted taxable income (minus a self-support amount of $31,046 in 2026), the time each parent spends caring for the child, and the number of children. The result is a formal assessment that sets out the exact amount payable.
What is the difference between a Binding and a Limited Child Support Agreement?
A Binding Child Support Agreement is a formal, long-term arrangement that requires both parents to obtain independent legal advice before signing. A Limited Child Support Agreement does not require legal advice, is simpler to enter, and is valid for up to three years. Both allow parents to agree on amounts and expenses beyond the standard Services Australia assessment.
Can child support payments be changed after an agreement is made?
Yes. Child support amounts can be varied if there is a significant change in circumstances, such as a substantial change in either parent’s income, a change in care arrangements, or a large unexpected medical expense. Parents can apply to Services Australia to reassess the amount, or seek legal advice about varying an existing agreement.
