Step-by-step guide to buying Bitcoin with Commonwealth Bank

CommBank customers usually buy Bitcoin by sending OSKO/PayID to an AUSTRAC registered exchange. Follow our guide below.

1. Pick an AUSTRAC-registered exchange
   CoinSpot, Independent Reserve, and Swyftx are popular choices registered with AUSTRAC and well-supported by CBA transfers. Avoid unregistered or offshore platforms to reduce block risk.
2. Create your exchange account
   Sign up with your email address, set a strong password, and enable two-factor authentication before depositing.
3. Complete identity verification (KYC)
   Upload your driver's licence or passport and confirm your details. KYC is required before deposits are enabled on any AUSTRAC-registered exchange.
4. Get the exchange's PayID or bank details
   In the exchange app, go to Deposit then AUD then PayID or Bank Transfer. Copy the PayID (usually an email or phone number) or the BSB and account number.
5. Open CommBank app and send via Osko/PayID
   In the CommBank app, tap Pay Anyone, enter the exchange's PayID or BSB and account number, and enter the exact payment reference from the exchange. Keep the transfer well under your $10,000 AUD monthly limit.
6. Wait for funds to arrive
   PayID/Osko transfers typically arrive within seconds to a few minutes. Your very first transfer to a new exchange may be held up to 24 hours while CBA reviews it. This is a one-time check.
7. Purchase Bitcoin
   Once the AUD appears in your exchange account, select BTC, review the current price, and confirm your purchase.
8. Secure your Bitcoin
   For long-term holding, transfer BTC to a personal hardware wallet. For active trading, keeping it on the exchange is fine but carries custodial risk.

Frequently Asked Questions

Can I buy Bitcoin with CommBank?

CommBank does not sell Bitcoin in the CommBank app, but you can buy BTC by funding an AUSTRAC-registered exchange like CoinSpot or Independent Reserve via Osko/PayID. CommBank caps all crypto exchange payments at $10,000 AUD per calendar month, and this limit is shared across all your CBA accounts combined, not per account. Card payments to crypto exchanges are blocked entirely, so bank transfer via PayID is the only reliable route.

What is CommBank's $10,000 monthly crypto limit?

CommBank applies a $10,000 AUD cap per calendar month on payments to cryptocurrency exchanges. This limit applies across all your CBA accounts combined: if you have a transaction account and a savings account with CommBank, the total across both counts toward the $10,000 cap. The cap resets at the start of each calendar month. If you need to move more than $10,000 AUD per month, you will need to use an additional bank account at another institution such as NAB or Up Bank for the overflow.

Why was my CommBank transfer to a crypto exchange blocked?

The most common reasons for a blocked CommBank crypto transfer are: (1) you have reached the $10,000 AUD monthly cap across all your CBA accounts, (2) the exchange you are trying to pay is on CommBank's blocked list (CommBank blocks certain exchanges it considers high-risk, including Binance in some periods), or (3) your first payment to a new exchange is being held for up to 24 hours while CommBank reviews it as a routine fraud check. Try a smaller test transfer first, and confirm you have not already reached your monthly cap.

Does CommBank block card payments to crypto exchanges?

Yes. CommBank blocks debit and credit card payments to cryptocurrency exchanges. This is a firm policy, not just a risk flag. Bank transfers via Osko/PayID are the only practical method for moving AUD to a crypto exchange from CommBank. Attempting card payments will result in a decline, and repeated declines can sometimes prompt a temporary fraud review on the card.

Does CommBank support PayID for crypto exchange deposits?

Yes. PayID via the Osko/NPP network is the recommended funding method for CommBank customers buying crypto. Most major AUSTRAC-registered exchanges, including CoinSpot, Independent Reserve, and Swyftx, offer a PayID deposit option. In the CommBank app, go to Pay Anyone, enter the exchange's PayID address, and include the exact payment reference provided by the exchange. Osko transfers typically settle in seconds to a few minutes.

What taxes apply to Bitcoin profits for CommBank customers?

The Australian Taxation Office (ATO) treats cryptocurrency as a capital gains tax (CGT) asset for most investors. When you sell or exchange crypto at a profit, you may owe CGT on the gain. If you hold for more than 12 months, a 50% CGT discount typically applies for individuals. Crypto used as a personal use asset for small transactions may be exempt, but trading activity is generally taxable. CommBank's banking transactions do not affect your tax treatment: it is determined by how you use the crypto, not which bank you fund through. Keep records of every purchase date, cost, and disposal.
