Mate, if you want to come out here to live, push for the same salary that you get back at home,

+accomodation (including utilities)
+vehicle (if you can)
+all schooling paid for kids up to 18
+flights home for entire family (up to 18years old) at least once a year
+no tax
+10%

Unfortunately I dont quite get that deal.

For some people the financial viability of being out here is marginal, if you look at your expenses and standard of living that you will be having.
