You're right,
Balinda - not an eay one, however obviously employers (such as those I have mentioned above) have some sort of idea, as would the pilots who left overseas jobs to return for work with
VB.
Perhaps some of these chaps might like to give us an idea.
I'll kick the ball off by saying that a couple of the chaps who left here, to go to Virgin Blue, received a salary DECREASE of approx. USD5,000 per month AFTER tax, (and forfeited free accomodation, utilities, and medical insurance) - the salary amounts to about AUD114k free of tax! Of that, I'd guess that "cost of living" (groceries, etc) would account for a difference of about AUD14k, giving a "Lifestyle Cost" in their case of
AUD110k/USD57.9k p.a.
