The Administrative Appeals Tribunal is not a rubber stamp. It genuinely reassesses visa decisions and, in many cases, substitutes a favourable decision where the original refusal was wrong or where new evidence changes the picture. But winning an AAT appeal requires preparation, the right evidence, and understanding what the Tribunal is actually looking for.
Here is a practical guide to the process.
What the AAT Actually Does
The AAT conducts a merits review of a decision. This means it considers your case independently, with fresh eyes. It can look at evidence that was not available or not included when the original application was made. It is not limited to finding errors in the delegate’s reasoning. It can simply reach a different conclusion on the same or new facts.
This distinction matters. AAT proceedings are an opportunity to build and present a stronger version of your case, not just to argue that the Department made a mistake.
How to Lodge Your Application
To start an AAT review, you lodge an application with the Tribunal within the time limit stated in your refusal letter. For most onshore visa refusals, this is 21 days from the date of the decision letter. For some visa types, the window is different. Do not miss it.
The application is lodged online at aat.gov.au. You will pay a lodgement fee. As of 2026, the fee for a migration review is around AUD 3,830, though a reduced fee may be available for eligible applicants. If you win your case, the fee is refunded. If you settle or withdraw, it generally is not.
The Process After Lodgement
After lodging, you enter a waiting period that is typically several months long. The Tribunal will assign your case a case number and eventually schedule a hearing.
During this period, you should be preparing your case. This means gathering evidence, obtaining witness statements, preparing your own statement, and reviewing the Department’s decision record (called the S56 material or the case file, which the Tribunal will release to you).
What Evidence Matters
Evidence that was not included in the original application is often the key to a successful AAT outcome. This might include updated financial records, new character references, additional proof of a genuine relationship, employment records, country conditions information for protection visa matters, or expert reports.
Think about why the application was refused and work backwards. What evidence would directly address the Tribunal member’s concerns? What would show that the decision-maker got the facts wrong, or that circumstances have changed?
Statutory declarations from the applicant and witnesses are powerful if they are specific, credible, and address the refusal reasons directly. Vague character references add little. Detailed, personalised statements from people who know the applicant well and can speak to the specific issues carry much more weight.
The Hearing
Most AAT migration matters involve an oral hearing, though some are decided on the papers. At the hearing, you or your representative present your case, and the Tribunal member may ask questions. The Department is not typically present at AAT migration hearings.
The hearing is not adversarial in the way a court proceeding is. The Tribunal member is genuinely trying to reach the correct decision based on the evidence and the law. Present clearly, answer questions directly, and bring all your documentary evidence organised and easy to navigate.
What Makes the Difference
Cases that succeed at the AAT generally have one or more of these elements: strong, specific evidence that directly addresses the refusal reasons; a well-prepared oral statement that is credible and consistent with the documentary evidence; legal arguments that correctly identify the law the delegate misapplied; or updated circumstances that change the assessment.
Cases that fail tend to lack new evidence, rely on generic character references, or simply repeat arguments that did not succeed at the original application stage without adding anything new.
Working With a Migration Agent or Immigration Lawyer
For straightforward merits review matters, an experienced registered migration agent can represent you at the AAT. For cases involving complex legal arguments, judicial review risks, or especially high stakes, working with a migration lawyer is advisable.

Frequently Asked Questions
Can I present new evidence at the AAT?
Yes. This is one of the main advantages of the AAT process over other review mechanisms. You can and should present any evidence that supports your case, even if it was not submitted with the original application.
How long does an AAT case take?
Processing times vary significantly depending on the case type and the Tribunal’s workload. Most migration review cases take between 6 and 18 months from lodgement to decision.
What happens if I win?
If the AAT sets aside the refusal and grants the visa, the visa is issued according to the Tribunal’s decision. You do not need to reapply.
