I have been granted the partner visa, both my wife and I are current living outside of AUS. And there are two conditions, the first one is a 8502 condition, entry after XXX (the name of my wife), the other is condition 8504, entry before 31 July.1. For the wording “After”, is there any specified requirement? Can I take the same flight with my wife, and my wife goes to Customs first, I wait her go, then I go?2. Is 8502 and 8504 a one-time requirement? For example, can my wife go to other countries after our entry to Aus? Also, can I made my first entry before 31 July, then I travel to other countries after 31 July, and go back to Aus in October?Thanks!
