Parties (including Centrelink) who are dissatisfied with an initial review of a Centrelink decision by the Administrative Review Tribunal may seek a further review (a 'second review' or 'tier two review') by the Tribunal. Second reviews are mainly governed by the Administrative Review Tribunal Act 2024 (Cth).

Applications for a second review must be lodged within 28 days of receiving the initial ART decision in writing. The Tribunal may extend this timeframe but only if it considers it reasonable in all the circumstances to do so [Administrative Review Tribunal Act 2024 (Cth) s 19].

An application for a second review may be lodged online, by email or written application, in person or by calling 1800 228 333. Visit the ART Centrelink payments webpage for more information.
