Well really if your going to go to college there, all you really need to do is find a a college that supports what you want to study. Apple for student vise (shouldn't be too hard for you probably have a US pass port ) so job done. Its a lot easier then it seems xD
Slight faster: Go to Uni/college there
Somewhere near Mongoslia?
What do you plan to do to earn a living in Austaslia once you get there?
And that would be a good plan. The medical profession (nursing, etc) is always a pretty good bet.
