Delta Six,
Pretty good advice and I would agree that there are possibilities out side OZ but very few right now. I used to fly in Africa bit I know there is no hiring going on this year for instance.
This is a global recession and it has made its self felt in most of the far off places you mention. But that is not to say in a few months or years thing maybe a lot better. To be honest I have flown up North for a couple of years in the past and it was pretty good but it had nothing on my time in Africa in terms of gaining experience and being exposed to unusual situations and not to forget seeing an amazing continent.
But what ever you get as a flying job remember to enjoy it and not wish it away for the next job.
