As an Aussie who actually tops up in Bitcoin, here’s the straight talk. The Australian Taxation Office treats crypto as property, not cash. When you spend, sell, or swap crypto, you trigger a Capital Gains Tax (CGT) event.
Depositing BTC into a bitcoin casinos wallet is “spending” in tax language. That means a disposal happens at the market value of your coins at that moment. If that value is higher than what you paid, there’s a capital gain; if lower, a capital loss.
