" A BVA lets you temporarily stay in Australia. It will usually end when you leave Australia. If you travel outside Australia, you need a visa to return. You can do one of the following:
- apply for and be granted a Bridging visa B (BVB) before you travel (if you do not have a substantive visa that allows you to travel or if your substantive visa will expire before you return)
- travel on your current substantive visa (if you have one that allows you to travel and enter Australia on your intended arrival date).
If your substantive visa ends while you are outside Australia and you do not hold a BVB, you will need to apply for and be granted a substantive visa before you can return to Australia. There is no guarantee that you will be granted a visa."
