Hello, I am a Bulgarian citizen and I live in Bulgaria with my Colombian wife. We would like to travel to Australia on holiday and we need different type of visas. From what I see I need to get e651 and my wife needs visa 600. My question is is it possible somehow to apply together? My wife does not work currently and I guess it would be quite hard to get this visa. I know some Australian guys who live in Australia, would it be easier if they send us something like an invitation?
