Move On
It's now a minimum of 2 years full time out of Oz before you can claim you are no longer a resident before the ATO stops taxing you.
If you are married with children, all of you have to be out of the country for 2 years minimum.
So the first 2 years you will be paying the Ozzy tax rate, on the 3rd you will adopt the current countries tax rate 15% etc.
That is incorrect. Generally the ATO will accept your application for non-residency for tax purposes if you “intend” to live out of Australia for an extended period of time, generally two years. If you meet the non-residency requirements you are a non-resident from day one and pay no Australian tax.
Where people fall foul of the ATO is in situations where they are on secondment overseas for a fixed period of time with the intention of returning to Australia on a particular date or they keep their family in Australia.
Contrary to popular belief expats can also own property in Australia and still be a non-resident for tax purposes as long as they don’t use it as their primary place of abode. Keeping it as an investment property or a holiday house is perfectly acceptable with the ATO.
