Miss Saigon, for a start if you've been in "Aus now for 8 years" You're out of touch, and can't really comment on the difference. So I'm guessing that what pretty much make you full of drivel, so to speak.
If you were somewhere left of Taupo as your profile reads of course your expensive lifestyle in Syd or Perth will be far more expensive than that you had experienced in good ol NZ.
If you're happy to come home and live in AUCLAND to be paid 65,000 flying an A320 then go right ahead. After all this is what this thread is about. I'd imagine you'd have a similar amount of complaints to that of where you are living right now as you seem to be quite a passionate individual.
