Believe it or not, UK has a much better opportunity to get onto decent equipment.
Oz, there's "only" QF, Virgin Blue or maybe NJS for jets. There are a few turboprop operators but the scene is still pretty shaky after the Ansett collapse.
USA, I believe if you are a white anglo saxon male then you need thousands of hours + a college degree for the majors. The regionals don't really pay enough to survive unless you have another job. (FO positions especially).
Hey, what's wrong with the glorious UK weather?
