Following announcement is made by Tasmania state nomination authority in regard to the applicants holding Bridging Visa A and affected by s48 bar and travel bans.
Bridging Visa holders: s48 bar - unable to lodge due to travel restrictions
If supported for visa state nomination a Subclass 491 applicant who holds a Bridging Visa A, B, C or E while seeking review of a decision would be required to depart Australia in order to lodge their visa application with the Department of Home Affairs. While travel restrictions are in place many applicants will find it difficult to depart Australia and all will be unable to enter Australia (unless exempt).
In an effort to manage this situation, as of 2 April 2020 all applications on hand and lodged thereafter by candidates who hold a Bridging Visa associated with Administrative Appeal Tribunal (AAT) or Federal Court review will continue to be assessed as normal. Unsuccessful applicants will be advised of the outcome and should not reapply until travel restrictions are lifted. All other applications will be placed on hold in our system and when travel restrictions are lifted, we will contact applicants to obtain an update of circumstances (such as current residential location and employment details if applicable) to then finalise their application accordingly.
