Great question Ausie,,,,
Some positions make near 20K a month US, but those guys are in HK where you have to pay 16% taxes and a whopper of a lease payment for their flat each month.
After you are all in, the China / HK / Macau jobs all pay out the same, which is 12-14K USD per month after tax and flat payment. This is for a guy with 500 hours on type and 1,000 slogging around the whole world.
