Tribunal review of visa cancellations
If your visa has been cancelled under s 501 of the Migration Act 1958 (Cth) then, unless it was cancelled by the Minister personally, you have a right to apply for merits review to the Administrative Appeals Tribunal (AAT).
Mandatory visa cancellation
If you receive a notice of visa cancellation under s501(3A) of the Migration Act 1958, you must act fast if you wish to regain your visa. If you wait longer than 28 days to respond to the cancellation, in many cases you will lose your right to challenge it.
