The case for reforming Australia's child support scheme
Five structural problems sit at the heart of the crisis. Here is what is broken, what sensible reform looks like, and how Parliament can deliver it.
The child support scheme is not failing because of a few unlucky cases. It is failing because of design choices made years ago that no longer fit the way Australians live and work. Below we set out the five problems we believe do the most damage, the principles that should guide their repair, and the practical, parliamentary route to lasting reform. None of this requires abandoning the idea that both parents should support their children — it requires honouring that idea properly.
Problem one
The rigidity of the assessment formula
At the centre of the scheme sits a formula. In principle, a formula is a good thing: it offers consistency and removes arbitrary discretion. In practice, the current formula is too blunt an instrument for the complexity of real families. It leans heavily on a single year's taxable income and a fixed picture of care, and it struggles whenever a family's circumstances depart from that tidy template — which, in modern Australia, is most of the time.
The result is assessments that can feel disconnected from reality on both sides of the ledger. A parent whose income has fallen sharply may still be assessed on last year's higher figure for months. A parent whose care arrangements have shifted may find the formula slow to recognise it. The rigidity that was meant to deliver fairness instead delivers outcomes that neither parent regards as fair, and the friction this creates spills directly onto the children.
Reform here does not mean throwing out the formula. It means building in the flexibility to reflect genuine change — faster recognition of real income, a more responsive treatment of care, and clearer pathways to correct an assessment that has plainly gone wrong, without forcing families into a fight to do so.
Problem two
Fairness to both paying and receiving parents
A recurring theme in the experience of separated families is that the scheme manages to leave both sides feeling wronged. Paying parents describe obligations they consider unrelated to their capacity to pay; receiving parents describe support that is inadequate, unreliable, or endlessly contested. When a system produces grievance on both sides simultaneously, the problem is rarely the people — it is the design.
We are firmly of the view that fairness is not a zero-sum contest. A scheme that treats paying parents fairly is more likely to secure consistent, willing payment, which is precisely what receiving parents and their children need. Conversely, a scheme that receiving parents trust to deliver is one that paying parents are more likely to accept as legitimate. Fairness to one side reinforces fairness to the other; unfairness to one side corrodes the whole.
The reform principle is balance. Assessments should rest on an accurate, current picture of each parent's circumstances. Enforcement should be firm where support is genuinely being withheld, but proportionate where a parent is doing their best in difficult conditions. The goal is a scheme both parents can recognise as even-handed.
Problem three
The treatment of self-employed and variable income
The scheme works least well precisely where the modern economy has moved most: self-employment, contracting, commission, seasonal work and income that swings from year to year. A formula anchored to a single tidy salary figure has no easy way to cope with a tradesperson whose earnings rise and fall, a small-business owner whose taxable income bears little resemblance to their cash position, or a contractor between engagements.
This cuts in two directions, and both are unfair. On one hand, a parent with genuinely variable income can be assessed on an unrepresentative figure and left unable to meet it. On the other, the scheme's blind spots can be exploited by a minority who arrange their affairs to understate what they truly have available, leaving their children short. Either way, the integrity of the assessment suffers, and trust in the scheme erodes.
Sensible reform would give the scheme better tools to assess real capacity for parents whose income does not fit a simple payslip — smoothing genuine volatility fairly, while closing the gaps that allow a determined few to avoid their responsibilities. The aim is accuracy: assessments that reflect what a parent can genuinely contribute.
Problem four
Administrative burden and the cost of disputes
Even where the rules are sound, the experience of dealing with the scheme can be punishing. Parents report long delays, opaque decisions, and processes that seem to demand enormous effort to achieve a straightforward correction. When something goes wrong, the path to put it right is too often slow, adversarial and exhausting — and every month a dispute drags on is a month of stress that reaches into the home and onto the children.
Disputes are not just stressful; they are corrosive. Prolonged conflict over child support entrenches hostility between parents at exactly the moment their children most need them to cooperate. A process that escalates rather than resolves is therefore not a neutral inconvenience — it actively works against the welfare of the children the scheme exists to protect.
Reform should make the system easier to deal with: clearer reasons for decisions, faster and less adversarial ways to resolve genuine disagreements, and an administrative culture oriented toward getting the right answer quickly rather than defending the first answer indefinitely. Reducing the burden is not a luxury — it is part of putting children first.
Problem five
The impact on children
Behind every assessment, every dispute and every delayed payment is a child. It is easy, in arguments about formulas and incomes, to lose sight of that. We refuse to. The ultimate measure of the child support scheme is not whether it balances the interests of adults, but whether it delivers for the children whose names never appear in the paperwork.
When the scheme fails — when support is inadequate, unreliable, or won only after a bruising fight — children pay in real terms: in material hardship, in instability, and in the emotional cost of watching their parents locked in conflict. A scheme that generates avoidable disputes is, in effect, manufacturing harm to the very children it was created to help.
This is why the welfare of children is the single thread running through every reform we propose. Accuracy matters because it protects children from going without. Fairness matters because it keeps parents paying and cooperating. A humane process matters because it spares children the fallout of needless conflict. Reform, properly done, is reform for them.
What good reform looks like
Principles for a fairer scheme
A more responsive formula that reflects parents' real and current circumstances, not a frozen snapshot.
Balanced treatment of both parents, so that fairness to one strengthens fairness to the other.
Smarter handling of self-employed and variable income, assessing genuine capacity while closing avoidance gaps.
Faster, less adversarial dispute resolution that resolves problems instead of entrenching them.
A children-first test applied to every rule and every change the scheme makes.
The path to change
How Parliament can deliver reform
Child support is governed by Commonwealth legislation, which means meaningful reform runs through the federal Parliament. That is both a challenge and an opportunity. It is a challenge because changing the law is slow and demands broad support. It is an opportunity because a well-made, non-partisan case can win that support — reforms grounded in fairness and the interests of children are exactly the kind that members across the chamber can get behind.
Our aim is to do the groundwork that makes reform possible. We aim to bring members of Parliament credible evidence and practical, ready-to-use options; to brief them on the human cost of leaving the scheme as it is; and to encourage the kind of considered review — whether through a committee inquiry, a department-led examination, or a private member's initiative — that turns a good idea into a durable law. We have not yet achieved these changes, and we will not claim otherwise. What we offer is a clear case and the persistence to keep making it.
Reform on this scale is a marathon, not a sprint. But it is achievable, and it is worth the effort. A child support scheme that is accurate, balanced and humane is within Australia's reach — if enough of us make the case for it, patiently and to the people who can act.
