Are gambling winnings taxable in Australia?

For most Australians, gambling winnings aren't taxable income. The ATO treats recreational gambling as a hobby, not a business activity, which means your casino wins generally don't get added to your assessable income. This applies whether you win in cash, chips, or crypto.

There's a narrow exception: if the ATO considers you a professional gambler (someone who gambles with a commercial, systematic approach intended to produce income) your winnings can be treated as ordinary income. For the vast majority of players, that threshold is never reached.

The tricky part isn't the gambling winnings themselves. It's the crypto you use to play with.

How the ATO treats cryptocurrency

The ATO classifies cryptocurrency as a capital gains tax (CGT) asset, not currency. That distinction matters every time you move it. When you deposit crypto at a casino, you're disposing of an asset. If that crypto has gone up in value since you bought it, the disposal can trigger a CGT event, regardless of what you do with the proceeds at the casino.

Put simply: you could break even at the tables, or even lose, and still owe tax on the crypto gain you realised when you made the deposit. This catches a lot of crypto gamblers off guard. The gambling result and the CGT calculation are completely separate.

Capital gains tax: a worked example

Say you buy 0.1 BTC when Bitcoin is trading at $50,000 AUD per coin. Your cost base is $5,000 AUD. Bitcoin later rises to $100,000, making your 0.1 BTC worth $10,000. You deposit that 0.1 BTC at a crypto casino.

That deposit is a CGT event. You've disposed of an asset with a $5,000 cost base for $10,000, realising a $5,000 capital gain. That gain goes on your tax return regardless of whether you win or lose at the casino.

If you held the BTC for more than 12 months before depositing, you're eligible for the 50% CGT discount. Only $2,500 of the gain is then assessable income. The same logic runs in reverse: if Bitcoin dropped before you deposited, you have a capital loss that can offset other gains.

What records you need to keep

Good records aren't optional if you're using crypto at casinos. The ATO expects you to account for every acquisition and disposal.

Track the date, amount, and AUD value of every crypto transaction, including casino deposits and withdrawals. Most exchanges provide downloadable transaction histories in CSV format. Tax software like Koinly or CoinTracker can import these automatically and produce ATO-compatible CGT reports. If you use multiple wallets or exchanges, pull records from all of them.

Keep records for at least five years. The ATO can audit returns from prior years.

The legal context: offshore crypto casinos and the IGA

Australia's Interactive Gambling Act 2001 (IGA) prohibits operators from offering certain real-money online casino games to Australian residents without a licence. Most crypto casinos operating internationally aren't licensed in Australia and sit in a legal grey area under the IGA.

Playing at these sites isn't a criminal offence for Australian players under current law, but they operate outside Australian consumer protection frameworks. The ATO's tax obligations apply regardless of where the operator is based. If you're unsure whether a site is on ACMA's prohibited services list, check the ACMA website directly.

When to get professional advice

If you gamble with crypto regularly, hold significant positions, or aren't sure how to report your transactions, speak to a registered tax agent with experience in digital assets. CGT calculations across multiple wallets and financial years can get complicated fast.
