1. who says australia is not allowed to raise big military? big miltary costs money ... that may be the reason but no country ever put a limit on their recruitment. In fact, the new australian govt. pulled out its troops from Iraq much to america's dislike.
2. Yeah, australia was a british colony and so britishers live there but so was USA - some 230 years ago.
3. For purpose of high salaries, several desies are working in USA, UK and in australia .... so what's great about that argument of yours. I bet that there are more Indians working in USA than there are australians in the USA.
