For some reason, everyone’s an expert when it comes to migration. There are over 70 different types of visa for Australia. The Migration Act of 1958 and the Migration Regulations of 1994 are like a couple of phonebooks in thickness, and many of the Laws and Regulations change several times per year. And there is very little consistency across the different visa types. Beware of well-meaning friends! And PLEASE don’t seek advice from those annoying amateur-run “advice forums” on the internet. Just because somebody managed to get their own visa application refused does NOT qualify them to advise you on yours. They are actually breaking the law by giving advice when not registered with MARA. Stay away!
