Just to point out a few things, tax rate works out approx 38% flat with no tax free threshold or claiming tax back and no super paid. Salary stated about AUD7-9k less if you don't have 1000hours PNG time. Usually takes atleast 6 months to be checked to line for a new starter
Accom is fairly basic 1 bedder with 60's decor, but most importantly it's in a dodgy part of town with minimal security (2 break ins by raskals in past 6 months - luckily no one harmed). Safety and security a major issue.
Cost of living now expensive with stronger kina and phone / internet also slow and expensive. Unless you purchase your own car (expensive compared to oz) only limited opportunity to get out of the compound which usually involves driving straight to another compound. Freedom not as we know in Australia.
