hello i am an Australian citizen who has been married to an american citizen for almost 4 years now. we live in america at the moment but will be arriving in Australia mid to late February. he is coming over on a ETA visa and ill just be coming home. I've tried talking to immigration lawyers here but can not seem to get a clear answer but one of them said because he is coming from america he has a better chance of them "letting it slide" with the ETA as a "bridging visa". If he comes over on that visa will we be allowed to file for an extension or a subclass 820/801 or a 309/100 visa to apply to live with me in Australia?
