I treat staking rewards with "cost basis as income". E.g. you received a crypto reward valued at $10 which adds $10 to your taxable income at the moment of the reward. Later you sell that crypto for $15 because it's risen in value. Cost basis as income means you've made a $5 capital gain when selling it. That's $10 of income and $5 of capital gain. Staking rewards are, usually, two taxable events: the moment you receive it and the moment you sell it. If you are just stacking rewards then always remember they are income, valued in AUD, at the time of receiving the reward. On your tax return it will be a report on other income received.
