Do you have to wait 2 years to avoid capital gains?

Yes, for the primary residence capital gains exclusion, you generally need to have owned and lived in the home for at least 2 of the last 5 years before the sale, but these two years don't have to be consecutive; however, you can't claim the exclusion if you've excluded gain on another home in the prior two years, with exceptions for unforeseen circumstances like job changes or health issues. For other investments, holding an asset for more than one year qualifies for lower long-term capital gains tax rates, but selling before two years means short-term gains taxed at your higher ordinary income rate. 

What is the 6 year rule for capital gains tax?

The "6-year rule" for Capital Gains Tax (CGT) in Australia allows you to treat a former main residence as tax-exempt for up to six years after you move out, even if you rent it out, enabling you to avoid CGT on any growth during that period. You qualify by moving out, choosing to treat it as your main home for tax, and can reset the rule by moving back in. If you rent it out for longer than six years, only the portion of the gain after the six-year mark becomes taxable.
