i do not think u can compare USA n AUS coz it is not even close, hearing , reading n seeing all the life struggle abt the student in aus not finding jobs sleeping on the street , usa is way better, at least u don't have to hear that n anyone can find at least some kind of job( if not u r just too lazy), after graduation may be different story abt their PR system n tough job market in US n hard for GC. but i would still argue that USA is # 1 may by China after 20-30 yrs but right now nothing comes close to it. take it easy. peace.
GOOOOOOOOOOOOO USAAAAAAAAAAAA.
