Challenging a child support decision

Overview

The three levels of review

Australia's child support system provides a structured pathway for challenging decisions you disagree with. There are essentially three tiers, each more formal than the last:

• Internal review (objection): A fresh look at the original decision by a different officer within Services Australia. This is the mandatory first step and must be lodged within strict timeframes.
• Administrative Review Tribunal (ART): An independent tribunal that reviews Services Australia's decision afresh. The ART replaced the former AAT (Administrative Appeals Tribunal) in 2024 and operates with a focus on accessibility and fairness.
• Court proceedings: Appeals to the Federal Circuit and Family Court of Australia on questions of law. This is the most formal and costly option, reserved for cases where there's a genuine legal error.

In my experience, the vast majority of child support disputes are resolved at the first two levels. Court proceedings are relatively rare and should generally be a last resort.

Step 1

Internal review (objection)

If you receive a child support decision you disagree with — whether it's an assessment, a change of assessment outcome, or a care determination — your first option is to lodge an objection with Services Australia.

Key things to understand about internal reviews:

• Time limit: You generally have 28 days from the date of the decision to lodge an objection. In some cases, this can be extended, but don't rely on that — act promptly.
• Fresh decision: A different officer reviews the matter from scratch. They're not bound by the original decision and can reach a completely different outcome — including one that's less favourable to you.
• Evidence matters: This is your opportunity to present information that may not have been considered in the original decision. The stronger your evidence, the better your chances.
• Written process: Internal reviews are generally conducted on the papers, without a hearing. Clear, well-organised written submissions are essential.

I help clients prepare objections that are thorough, well-evidenced, and focused on the specific grounds that are most likely to succeed. A scattered, emotional submission rarely gets the result you want.

Step 2

Administrative Review Tribunal (ART)

If the internal review doesn't resolve your concern, the next step is to apply to the Administrative Review Tribunal. The ART is independent of Services Australia and conducts a completely fresh review of your matter.

What to expect from the ART process:

• Application: You apply directly to the ART. There's a small filing fee, though fee waivers are available in cases of financial hardship.
• Hearing: Unlike internal review, the ART typically holds a hearing — either in person, by phone, or by video. Both parties can present their case directly to the tribunal member.
• New evidence: You can present evidence at the ART that wasn't available during the internal review. This makes it a genuinely fresh look at your situation.
• Decision: The ART makes a binding decision that replaces the original Services Australia decision. The tribunal member has broad discretion to consider all relevant circumstances.

In my experience, the ART hearing is where preparation makes the biggest difference. I've seen well-prepared cases succeed at the ART that failed at internal review, simply because the evidence was presented more effectively.

Step 3

Court appeals

Appeals from the ART to the Federal Circuit and Family Court of Australia are available, but they're limited to questions of law — not disagreements about the facts or the exercise of discretion.

Court appeals are appropriate when:

• The ART made an error of law (misapplied the legislation or misunderstood a legal concept)
• The ART failed to consider relevant evidence or considered irrelevant material
• The decision was unreasonable in the legal sense (no reasonable tribunal could have reached that conclusion)

Court proceedings involve legal costs, formal procedures, and significantly longer timeframes. I'm honest with my clients about when a court appeal is genuinely worth pursuing and when it's better to accept the tribunal's decision and focus energy elsewhere.

Change of assessment

A separate pathway — the 10 reasons

It's worth distinguishing between the appeal pathway described above and a change of assessment application. These are different processes that address different problems.

A change of assessment isn't about challenging a wrong decision — it's about asking Services Australia to depart from the formula because of special circumstances. The legislation recognises ten specific reasons, including:

• High costs of caring for the children (reason 1)
• High costs of contact with the children (reason 2)
• A parent's income, property, or financial resources (reason 8)
• A parent's earning capacity (reason 8A)
• That the formula assessment is otherwise unfair (reason 10)

Change of assessment decisions can themselves be objected to and taken to the ART if the outcome isn't satisfactory. I regularly help clients with both change of assessment applications and the subsequent review process if needed.

How I help

Guidance through every stage

Whether you're lodging an objection, preparing for an ART hearing, or considering a court appeal, I provide practical, informed guidance at every step:

• Assessing whether your case has genuine prospects of success before you invest time and money
• Preparing clear, evidence-based submissions for internal reviews
• Helping you prepare for ART hearings — what to expect, what to say, and what evidence to present
• Advising on the strategic choice between different review pathways
• Honest assessment of when to pursue further and when to accept an outcome
