When a candidate leaves Australia after their travel validity expires, or if their visa expires when they are outside Australia, they aren’t permitted to return to Australia as a permanent resident. This is when they will require the Resident Return Visa 155. This visa allows the holder to come to Australia as a permanent resident in case their travel validity expires. With this visa, candidates may travel in and out of Australia as often as they want until their travel validity expires. Candidates may have a travel facility for up to 5 years. However, this depends on case to case. The Subclass 155 visa is processed in less than 1 day for 25% of applications and in 3 days for 75% of applications.
