With all this offshoring of pilots jobs, I wonder if the Australian Taxation Office would like to start taking a closer look?
Unless one divest's themselves of every Australian asset you are up for Aussie tax. Aussie tax rates on what could only be described as "Coolie wages" would make some/most of these contracts totally and absolutely untenable
Taxed on the income your assets produce at about 30%. But, importantly for your argument, you are not taxed on wages.
However, the ATO may want to have a close look at where the pilot bases his family. How much time is he spending in Australia? He could be deemed a resident for tax purposes and yes the coolie wages won't be so good.
