Emailed Question:
I am a travel agent and have a client with British Passport. he has a re entry visa into Aust. indefinitely but he has recently had to renew his passport. does he have to apply for a new re entry visa for his new passport or can he just carry his expiry passport with the valid re entry visa inside.
My Answer:
If they hold an Authority to Return or Return Endorsement, they should not apply for any other visa, including a Resident Return visa because, if their application is approved, this will legally cease their Authority to Return or Return Endorsement.

This is from one of the above pages:
If you get a new passport and your visa is still valid for travel, you will need to complete Form 929 – Change of address and/or passport details, and return the form to the department. The department will link your new passport details to your current visa (and other records). There is no fee for this service.

Some ATR/RE holders may experience significant delays when they enter Australia while manual checks are made.
