Hi i applied 801/820 visa last month for my partner which is (WA801) not in effect yet because he is holding 457 which is till 2020. We moved far from his previous work place that is costing us now 4hrs drive+50/day fuel cost. He wants to cancel his 457 visa: what is alternative to stay in aus while he is waiting for 801 visa processing? Is that effect his 801 visa?... help me please
