Why Everyone Is Unhappy About Child Support in Australia
Written by Pippa Colman
This article delves into some of the intricacies and challenges of the Australian child support system, illustrating why both payers and payees are unhappy with current child support arrangements.
Australia’s child support system was created to ensure children continue to receive financial support from both parents after separation. While the system has an important purpose, it is also heavily criticised. Many parents who pay child support believe the system is unfair, while many parents who receive child support payments say the payments are inadequate, unreliable, or difficult to enforce. The result is that both sides often leave the process frustrated.
A Brief History of Child Support in Australia
In 1988, the Child Support Agency (“CSA”), now part of Services Australia, was established to collect child maintenance payments in accordance with existing orders and the Child Support (Registration and Collection) Act (Cth). In 1989, the Child Support (Assessment) Act introduced a formula-based system to calculate child support obligations and child support assessments.
The goal was to create a fair and consistent system so that children would continue to be financially supported by both parents after separation. Today, child support is assessed using a formula that considers:
Each parent’s taxable income;
The ages and number of children;
The costs of raising children; and
The percentage of care each parent provides
(ie the time the children spend with each parent).
The formula also deducts an amount for self-support and adjusts for relevant dependent children from other relationships. Although the system was designed to reduce conflict and provide certainty, the Australian child support system has been, and continues to be, a significant source of dissatisfaction for separated parents and families navigating family law matters.
How Many Families Are Affected by Child Support?
According to the Services Australia annual report for the 2024 to 2025 financial year, approximately 1.1 million children in Australia are supported by the child support system. Despite a significant number of children being supported by this initiative, roughly one-third of parents have outstanding child support debt.
Billions of dollars in unpaid child support remain outstanding across Australia. In December 2025, approximately 153,000 parents had a child support debt totalling $1.9 billion.
Reports published in recent years, including a Commonwealth Ombudsman investigation privately conducted for ABC News in 2025, suggest that unpaid child support disproportionately affects mothers, who make up the majority of receiving parents (84%).
The 50/50 Care Urban Myth
There is an urban myth that 50/50 care arrangements result in no child support changing hands. The reality is that the higher income earner is usually assessed to pay child support to the lower income earner.
Another reality is that if the care of the children is about equal, often the lower income earner does not seek a formal child support assessment through Services Australia. The amount of child support payable varies. Pension recipients typically pay a minimum child support rate of about $10.60 per week ($551 per year) for child support periods starting on or after 1 January 2026.
Professor Kay Cook from Swinburne University of Technology studied the child support system and said the way the federal government calculated payments had always been artificially low, and inflation has made it worse. Data reveals that more parents are falling behind, whereby in the last financial year there was a $50 million shortfall between what was owed and what was collected.
Why Paying Parents Are Unhappy About Child Support
There is no doubt that separation places significant financial pressure on families, particularly where one income is required to support two households.
Critics of the Child Support Agency (CSA), including separated parents and advocacy groups, often argue that the formula used by Services Australia is outdated, unfair, inefficient, and fails to properly account for individual circumstances. Complaints commonly include the accumulation of large child support debts, the complexity of the child support assessment process, and concerns that the system can be weaponised and used as a source of ongoing conflict between former partners, whereby former partners may withhold children if payments are not made or constantly seek reviews of child support assessments.
Paying parents frequently express unhappiness with the child support system due to perceived inequities in payment calculations, particularly if they are self-employed, operate businesses, or earn irregular income through commissions or bonuses. In these situations, the formula-based child support assessment may lead to outcomes that feel disproportionate or disconnected from their actual financial position, contributing to financial stress and resentment for the paying parent.
Paying parents also often wish to have greater transparency regarding how child support payments are spent. Currently, the paying parent has no formal way of knowing how their child support payments are used.
Why Parents Who Receive Child Support Are Unhappy
Parents who receive child support, most commonly mothers, often face frustrations with irregular, unpredictable, or unpaid child support payments. Even where enforcement measures exist, the amounts collected may still fall short of meeting the actual costs of raising children, particularly given rising expenses for housing, childcare, education, medical expenses, and everyday living costs.
Many parents receiving child support also find the administrative process daunting and time-consuming to navigate. Obtaining reassessments, pursuing unpaid child support, or responding to disputes can involve significant paperwork, delays, and ongoing communication with Services Australia, adding further stress to already challenging circumstances following separation or divorce.
A common criticism of the current system is that it relies heavily on self-reported income information. There is also no effective mechanism to compel a parent paying child support to lodge outstanding tax returns so that child support can be accurately calculated.
Further, in some cases, a parent paying child support may report a very low taxable income despite appearing to enjoy a significantly higher standard of living. Where a parent receiving child support believes the other parent is not disclosing their true financial position, the burden often falls on the receiving parent to seek a formal review through Services Australia. This process can be difficult and requires paperwork, time, and evidence supporting the belief that the paying parent’s true income is higher than disclosed.
It can also be disheartening for the parent receiving child support when they see their former husband or wife re-partner and apparently enjoy a comfortable lifestyle, while their own household struggles financially.
What Does It Cost to Raise a Child in Australia?
There are no recent comprehensive studies about the cost of raising a child in Australia. However, according to SBS News published on 14 January 2026:
a. Families spend about 13 per cent of their disposable income on the first child and a further ten percentage points for each child after that;
b. For a working-age couple earning the typical after-tax income (around $130,000 per year), that equates to about $17,000 per year for the first child and around $13,000 per year for each subsequent child. That works out to approximately $320 per week for the first child and $246 per week for later children.
That means to raise the eldest child to adulthood, the couple would spend about $300,000 over 18 years in today’s dollars. Subsequent children would cost approximately $230,000 each.
Changing Child Support Assessments
Child support assessments can be reviewed when there is a significant change in circumstances, such as income variation or changes in parenting arrangements and care arrangements for children.
The process involves strict guidelines and requires considerable evidence, creating barriers for parents seeking necessary adjustments. This complexity often discourages reviews, contributing to broader dissatisfaction by both paying and receiving parents.
Enforcement of Child Support Debt
There are a number of options available to parties seeking to recover outstanding child support debts, including:
1. Applications to the Federal Circuit and Family Court of Australia
In limited circumstances, parents may seek the intervention of the Court in relation to issues such as the enforcement of unpaid child support, disputes about parentage, departure from administrative assessments, or the interpretation and enforcement of child support agreements.
However, the legal process can be lengthy and costly, adding to the stress and dissatisfaction for both parties. The reality is that these applications are rarely made and it is rarer still for orders to be made.
2. Departure Prohibition Orders
A Departure Prohibition Order (DPO) is a legal mechanism available to the Australian Taxation Office or Child Support Agency to prevent individuals with significant tax debts or child support debts from leaving Australia before payment is made.
While sometimes effective in compelling payment, these orders can be viewed as excessive or harsh, particularly if they impact the paying parent’s ability to earn income overseas.
3. Notices to Third Parties Holding Monies Due to a Payer
The Child Support Agency also has the authority to issue notices to third parties, such as employers or financial institutions, to redirect funds from a payer’s account to cover unpaid child support.
While this ensures payment for the receiving parent, it can affect the paying parent’s financial stability and heighten tensions, leading to further dissatisfaction within the child support system.
What Can Families Do to Reduce Child Support Disputes?
In many cases, families can reduce conflict and dissatisfaction about child support by reaching agreements privately, either at the time of separation or at a later stage.
Parents may be able to agree on matters such as:
a) What amount of child support is reasonable in their circumstances;
b) Which parent will pay for particular expenses in the future, such as school fees, medical costs, extracurricular activities, or sporting expenses;
c) Whether the family can realistically maintain the same lifestyle after separation, or whether financial adjustments will need to be made. This may involve difficult decisions about private schooling, hobbies, or other significant expenses;
d) Whether they wish to rely on the administrative child support system through Services Australia, or instead enter into a private child support agreement;
e) If entering into a private agreement, whether the arrangement should be flexible and reviewable over time, or formalised through a Binding Child Support Agreement intended to remain in place until the children reach adulthood; and
f) Whether the assistance of mediators, counsellors, or experienced family lawyers may help facilitate productive communication and negotiation.
Where parents are able to address child support as part of the broader separation and family law process, and remain focused on the best interests of their children, practical and workable solutions can often be achieved.
Unfortunately, where child support issues remain unresolved, disputes can continue for many years and become a significant source of ongoing conflict, resentment, and financial stress for both parents.
Conclusion
The Australian child support system plays an essential role in ensuring children continue to receive financial support following parental separation. Despite its important purpose, the system frequently leaves both paying and receiving parents dissatisfied.
Difficulties in achieving fair and timely child support payments, alongside the complexities of the legal and administrative processes, contribute to widespread dissatisfaction across Australia.
Addressing these issues requires systemic reform focused on transparency, fairness, and adaptability to changing financial situations. Only then can the system genuinely meet the needs of separated families and prioritise the best interests of children.
In many situations, parents taking a practical and cooperative approach to child support arrangements, including entering into private child support agreements where appropriate, may provide the most effective long-term solution for reducing conflict and supporting children after separation.
