Hi I have 489 visa right. I have almost completed 02 years stay and one year full time work. Now I have to apply for 887 visa next month. I am in Australia but my wife and kids are struck overseas due to covid 19 crises and travel restrictions. Our 489 visa will be expiring on 02 Nov 2021. Can somebody please help me regarding following queries: 1) If I submit 887 visa for myself, can I add my dependent subsequent family members for 887 visa later on, when they are able to travel to Australia? 2) what will be the effect on our application, if I submit 887 only for myself at this stage?
