Mate mate mate. this could go on forever and your tone indicates that you won't accept being proven otherwise.BUT......
What? That it wont go on forever?
The ATO will not give an individual ruling unless you want to pay for it. They will make an assessment on your return each year as applicable. They will of course give a general indication if you ask them the right questions.
Let me just reiterate what I have already stated in my previous. SOME people may be aussie residents ( Now your old mate bronwyn lived in her house, a little different if you don't or haven't. i.e. investment property). Each needs an individual ruling.
Well if you weren't living in a house then that is even better. You would now be RESIDING in Singapore which even further supports your claim to being a Non-Resident for Tax Purposes.
However If you don't/cannot/ or are unwilling due to the financial sheit that will bring..... well you know what happens.
Such as?
The facts dear boy, the facts.
