If an application for visa to stay in Australia is declined or a visa to stay in Australia got cancelled, immigration allows applicant submit an administration appeal tribunal(AAT) for a merit review of this decision. Application for merit review of this decision must be given to the AAT within 21 calendar days after the day on which visa decline received. Applicant may only seek merits review of the decision with the AAT if you are physically present in Australia at the time the application for merits review is made.
Immigration status during AAT:
During the processing of your visa application, generally a bridging visa is granted to you forthe duration of the visa processing period. When you make a valid application for merits review of this refusal decision then that bridging visa will remain in effect during the merits review proceedings. In some cases applicants need to apply for a new Bridging Visa.
