How to buy a property in Australia with Bitcoin legally
Purchase property as you normally would by paying deposit and other fees in AUD.
Once the property is in your name, pay it off by converting $9,000 AUD worth of BTC from your trading or exchange account to the bank account of the bank holding your property.
This way I think (not sure) that you'll avoid paying CGT on any crypto profits you've made.
You'll be paying off the property at 52 X 9 = $468k per year.
