The Administrative Appeals Tribunal (AAT) plays a pivotal role in the country's immigration system. It serves as an independent body tasked with reviewing decisions made by the Department of Home Affairs regarding visa applications, visa cancellations, and other migration-related matters.

The AAT provides individuals and businesses with the opportunity to challenge migration decisions they believe to be incorrect or unfair. This division covers a wide range of immigration issues, including partner visas, skilled visas, student visas, refugee and humanitarian visas, and visa cancellations on character grounds.

Through its review process, the AAT ensures that decisions made by the Department of Home Affairs are fair, lawful, and in accordance with Australia's migration laws and policies. It offers applicants a chance to present their case, provide additional evidence, and address any concerns raised by the department.
