I know a couple of aussies working for Emirates as engineers, a few in the hangar and a few on the line. The job is a mixed bag, some good and some not. Work is ok, the blokes ok, the real problems lay with the accomodation and schooling.
Money is ok but as the aussie dollar strengthens the salary goes backwards as it is linked to the US. The oz has gained 15% this year already, that means a 15% pay cut in oz dollar terms.
Dubai has a high standard of living but is an expensive place to live (more than oz so I hear).
Accomodation department is a disaster that have screwed up a lot of families and made live miserable for a number of people, they are probably the no.1 complaint from everybody I know who has ever worked there.
Schooling is expensive and the company do not pay all of it, the limited number of schools also means that places in schools are limited, depending on age.
Should you go ther? Depends on your own situation, but don't expect to get rich in paradise.
