Some ok advice given above. It really depends on what you want. Living in Asia is not like living in Australia (obviously). However there will be advantages and dis-advantages both career wise, and from a lifestyle point of view to each.
It can be also down to plain old luck. If your timing is right, you may have excellent career progression living in Oz..... or you may get the same or better career progression living in Asia.
For me, I would love to move back to and work in Oz..... but..... on my current leave system, with my current low tax rate, with my current guaranteed bonuses, and with my house being paid off by my employer, as a Direct Entry Captain. And the chances of that ever happening.... Zero!! So I accept my lifestyle in Asia (which at the end of the day is what you make of it, and personally it is very good), and the very quick career progression which I did not have in Australia.
Again, up to you and your needs.
