Sport, if you can live in Darwin, you can certainly manage most Asian cities. Why not get paid what you are worth considering your level of skill and responsibility, not to mention the considerable cost of your training ?
If you are happy on the sort of money most people working semi skilled jobs on the mines take for granted good for you.
Conditions in Australia are heading downwards, driven by oversupply of pilots willing to accept anything just to be home, and I can't see that changing anytime soon. "Of course I will work for $400/week, live in a donga, wash the aircraft and pay for my own endorsement, just give me a job."
Life here is great, if you can accept the differences.
