Dodgybrothers with all due respect you are not correct, 'Titan' and 'Keg' have it basically correct although another thing to consider is Private Health Insurance. You cannot remain with private cover in Aus. You also have to surrender your 'Medi-Card' and cannot contribute to an Aussie Super Scheme. If your principle address is off-shore, together with your employment and your country of residence has a tax agreement with Australia you don't pay Aussie tax on those earnings. You do, obviously pay aussie tax on any Aussie income, Shares, Bank interest etc. They are constantly changing the rules and the easiest thing is to contact them for a private ruling or go through a tax agent. I can come home 90 days a year, some have more, God knows why its different. You also cannot hold an ASIC, but can wander about the tarmac on your overseas ID as if you own the place. The only problem I can see is if they consider Jet Star an Australian company, again a private ruling will answer that one.
