Isabelle TorresWhat can you do when an Australian government agency makes a decision that affects your life — and you believe it got it wrong? Administrative law is the legal framework that governs how government bodies exercise power, and it provides citizens with the tools to challenge decisions, demand fairness, and hold agencies accountable.
Administrative law in Australia covers federal, state, and territory government decision-making. It applies whenever a government body exercises a statutory power — from visa refusals by the Department of Home Affairs to land use decisions by local councils. Understanding its principles is essential for anyone dealing with licensing, permits, social security, immigration, taxation, or regulatory enforcement.
What Is Administrative Law in Australia?
Administrative law is the branch of public law that governs the activities of government agencies, departments, and officials. In Australia, it regulates how these bodies make decisions, exercise statutory powers, and interact with citizens and businesses.
The primary sources of Australian administrative law include:
- The Administrative Decisions (Judicial Review) Act 1977 (Cth) — allowing judicial review of federal government decisions
- The Administrative Appeals Tribunal Act 1975 (Cth) — establishing the Administrative Appeals Tribunal (AAT)
- The Freedom of Information Act 1982 (Cth) — governing access to government documents
- Common law principles of natural justice and procedural fairness
- State administrative law equivalents (e.g., NSW Administrative Decisions Tribunal, VCAT in Victoria)
Administrative law is distinct from constitutional law, which establishes the framework of government, and criminal law, which addresses offences against the state. Its focus is on procedural fairness, accountability, and the proper exercise of statutory power.
What Are the Core Principles of Australian Administrative Law?
Three foundational principles underpin administrative law in Australia:
1. Procedural Fairness (Natural Justice)
Procedural fairness requires government decision-makers to provide affected parties with notice of the issues being considered and an opportunity to be heard before an adverse decision is made. The High Court of Australia confirmed in Kioa v West (1985) HCA 81 that procedural fairness applies to decisions affecting individual rights, interests, and legitimate expectations.
The two core rules are:
- The Hearing Rule: a person must be given a fair opportunity to present their case before a decision is made against them
- The Rule Against Bias: decision-makers must be impartial and must not have a personal interest in the outcome
2. Legality — Acting Within Jurisdiction
A government body must act within the powers granted to it by Parliament. If an agency acts ultra vires (beyond its legal authority), its decision can be challenged and invalidated. Courts will not uphold decisions that exceed statutory powers, even if the outcome seems reasonable.
3. Reasonableness and Rationality
Decisions must be rationally connected to the evidence before the decision-maker. In Minister for Immigration and Citizenship v Li [2013] HCA 18, the High Court held that an unreasonable decision — one that no reasonable person could reach on the material before them — can be set aside on judicial review.
How Can You Challenge a Government Decision in Australia?
When a government decision adversely affects you, Australian administrative law provides several avenues for review:
| Review Mechanism | Forum | What It Reviews | Cost |
|---|---|---|---|
| Internal review | The agency itself | Decision on its merits | Free |
| Merits review (federal) | Administrative Appeals Tribunal (AAT) | Substitutes a new decision | Filing fee: ~$100 |
| Judicial review (federal) | Federal Court / High Court | Legality of decision-making process | Significant legal costs |
| Ombudsman complaint | Commonwealth Ombudsman | Process fairness and maladministration | Free |
| FOI request | Agency + Information Commissioner | Access to government documents | Free (mostly) |
Merits review is the most accessible option for most Australians. The Administrative Appeals Tribunal (AAT) can examine the facts and substitute the original decision with a better one — something courts on judicial review cannot do. The AAT handles over 50,000 applications per year across its divisions [AAT Annual Report, 2024].
À retenir: Judicial review in Australian courts examines whether the decision-making process was lawful — it does not re-examine the facts. If you want the decision itself reconsidered, pursue merits review at the AAT first.
What Decisions Can Be Reviewed Under Federal Administrative Law?
The Administrative Decisions (Judicial Review) Act 1977 (ADJR Act) gives individuals and businesses the right to seek review of decisions made by federal government officials. A decision is reviewable if it was made under a federal enactment and affected legal rights or interests.
Common grounds for review under the ADJR Act include:
- The decision-maker exceeded their jurisdiction or authority
- There was a breach of procedural fairness (no hearing or biased decision-maker)
- The decision was not authorised by the relevant legislation
- Relevant considerations were not taken into account, or irrelevant ones were
- The decision was an improper exercise of discretion
- There was an error of law on the face of the record
The Federal Court of Australia hears judicial review applications under the ADJR Act. For migration decisions, the Federal Circuit and Family Court of Australia and the Federal Court have specialist jurisdiction. State and territory government decisions are reviewed under state administrative law statutes and common law.
What Is the Administrative Appeals Tribunal (AAT) and How Does It Work?
The Administrative Appeals Tribunal (AAT) is Australia's primary federal merits review body. It is an independent tribunal that reviews a wide range of government decisions on their merits — effectively stepping into the shoes of the original decision-maker and determining the correct or preferable decision based on all available evidence.
Key Divisions of the AAT
The AAT has several specialist divisions, including:
- Migration and Refugee Division: reviews migration and refugee visa decisions
- Social Services and Child Support Division: reviews Centrelink, child support, and family assistance decisions
- General Division: covers business, industry, security, and general administrative decisions
- Small Business Taxation Division: reviews ATO (Australian Taxation Office) decisions
Steps to Apply to the AAT
- Check eligibility: confirm the decision you want reviewed is subject to AAT review (a review rights notice should come with the original decision)
- Apply within the time limit: most applications must be lodged within 28 days of the decision (some have different timeframes)
- Lodge your application: online via the AAT portal at aat.gov.au, by post, or in person
- Attend a case conference: most matters go through an alternative dispute resolution process first
- Hearing: if unresolved, a formal hearing before a Member of the AAT is conducted
Most AAT matters are resolved without a formal hearing. In 2024, approximately 74% of finalised cases were resolved through alternative dispute resolution or settlement [AAT Annual Report, 2024].
What Areas of Life Does Administrative Law Govern in Australia?
Administrative law touches nearly every sector where government agencies exercise power:
- Immigration: visa grants, refusals, cancellations, and deportation orders by the Department of Home Affairs
- Social security: Centrelink payment decisions, income assessments, and debt recovery by Services Australia
- Taxation: ATO assessments, objections, and penalty decisions
- Environment and planning: development approvals, environmental licences, and land clearing permits by state planning authorities
- Occupational licences: licensing decisions by professional regulators (medical boards, legal professional boards, financial services regulators such as ASIC)
- Regulatory enforcement: decisions by the Australian Competition and Consumer Commission (ACCC), the Australian Securities and Investments Commission (ASIC), and sector-specific regulators
For businesses, administrative law matters are frequently triggered by licensing disputes, regulatory enforcement proceedings, and decisions affecting their ability to operate. For individuals, immigration, Centrelink, and ATO decisions are the most common contexts.
When Should You Consult an Administrative Lawyer in Australia?
Administrative law proceedings can be complex, and the stakes are often high — a lost visa appeal, an overturned business licence, or a wrongly denied Centrelink payment can have life-changing consequences. Professional legal advice is strongly recommended when:
- You have received a decision notice with review rights and are unsure whether to appeal
- Time limits for review are approaching (missing the deadline typically means losing your review right permanently)
- The decision involves complex statutory interpretation or procedural issues
- You are seeking judicial review in the Federal Court, where self-representation is particularly difficult
- Migration decisions are involved — immigration administrative law is highly technical and errors can be catastrophic
An administrative law solicitor can assess the merits of your case, advise on the appropriate review pathway, and represent you at the AAT or in court.
À retenir: Many administrative law solicitors offer initial consultations to assess your case. For AAT matters, legal aid may be available through your state Legal Aid Commission for eligible applicants.

FAQ: Common Questions About Administrative Law in Australia
Is the AAT the same as a court?
No. The Administrative Appeals Tribunal (AAT) is an independent tribunal, not a court. It conducts merits review — examining whether the original decision was the correct or preferable one — rather than the strictly procedural focus of judicial review in courts. AAT proceedings are generally less formal than court hearings, and parties can represent themselves, though legal representation is common.
What is the difference between merits review and judicial review?
Merits review (e.g., at the AAT) considers whether the decision itself was the right one based on all available evidence. The tribunal can substitute the original decision with a new one. Judicial review in courts examines only whether the decision-making process was lawful — courts cannot substitute their own decision for the agency's if the process was followed correctly.
How long do I have to apply for AAT review?
Time limits vary by decision type. Most AAT applications must be lodged within 28 days of the decision date. Migration decisions often have shorter timeframes — sometimes as little as 7 days. Always check the review rights notice attached to the original decision.
Can I access government documents about my case?
Yes. Under the Freedom of Information Act 1982 (Cth), you have the right to request access to documents held by federal government agencies. This can be a powerful tool in preparing for an AAT or judicial review application. State FOI laws apply to state government documents.
What happens if the AAT decides against me?
If dissatisfied with an AAT decision, you may be able to appeal to the Federal Court on a question of law. This is a more limited pathway — the Federal Court will not reconsider the facts — and legal representation is essential.
