Six Year Ruling

Hi There

Long time observer – and as always find the replies interesting and very helpful.

My question is "Having rented out my PPOR for over 5 years – what is the time frame the "ATO" in relation to the 6 year ruling.

When do you have to be living back at your PPOR?  Is it 1 week, 1 month, 6 months?  I cant seem to find out much info.  Obvisiously you want to make sure that you dont loose your "PPOR staus – and therefore have Capital Gains Tax to pay?

Any help/opinions would be great
