Australia replaced the Administrative Appeals Tribunal with the Administrative Review TribunalA body that independently reconsiders government decisions. (ART) on 14 October 2024, after the replacement plan faced parliamentary resistance over how members would be appointed. As the new tribunal handled a large and increasing caseload—described in August 2026 as more than 131,000 matters, particularly in migration—the government introduced this bill through Michelle Rowland MP on 1 July 2026 to streamline reviews, strengthen case-management powers and protect sensitive material, and the House passed it on 20 August 2026.
