According to the crypto asset transactions guide by the Australian Government, Capital Gains Tax should be considered when you dispose of your crypto asset. If you make a capital gain after a disposal, you may pay tax on it. A transaction involving a disposal takes place when you do any of the following: sell a crypto asset, gift a crypto asset, trade, exchange or swap a crypto asset for another crypto asset, convert a crypto asset to Australian or foreign currency (otherwise known as fiat currency), and buy goods or services with a crypto asset.
