Buying Bitcoin and other cryptocurrencies has become increasingly accessible for Australian investors, especially those using Commonwealth Bank (CommBank). While CommBank doesn’t offer direct crypto purchases through its platform, it enables users to transfer Australian dollars (AUD) to regulated crypto exchanges that comply with AUSTRAC’s strict anti-money laundering (AML) and counter-terrorism financing (CTF) standards.
This guide walks you through the complete process of investing in digital assets using your CommBank account—covering verification, deposit methods, purchase steps, and important policy restrictions like the $10,000 monthly transfer cap and 24-hour hold on crypto-related payments.
Step-by-Step: How to Buy Bitcoin Using Commonwealth Bank
1. Create and Verify Your Crypto Exchange Account
To begin investing, you'll need to sign up with a licensed Australian cryptocurrency exchange such as CoinSpot. These platforms are approved for bank transfers from major institutions like CommBank due to their compliance with AUSTRAC regulations.
During registration, you'll be required to provide:
- Full legal name (or business name, if applicable)
- Valid government-issued ID (e.g., passport or driver’s license)
- Email address
- Phone number
Identity verification is mandatory under Australian financial law. It ensures that all transactions are traceable and secure, protecting both investors and the broader financial system.

2. Deposit AUD from Your CommBank Account
Once verified, you can fund your exchange wallet by transferring AUD directly from your Commonwealth Bank account. The most efficient and cost-effective methods include:
- PayID: Instant, fee-free transfers up to $20,000 per day
- Direct Deposit (Osko/NPP): Real-time deposits with no fees, up to $100,000 daily
- Debit Card: 1.88% transaction fee, $1,000 limit per 24 hours
- PayPal: 0.5% fee, $5,000 daily limit (requires linking your CBA card)
These options allow seamless integration between traditional banking and digital asset platforms. PayID is particularly popular due to its speed and zero transaction costs.
Pro Tip: Always double-check recipient details before confirming any transfer. Crypto transactions are irreversible once processed.
3. Buy Bitcoin or Other Cryptocurrencies
After your AUD deposit clears—which may take up to 24 hours due to CommBank’s fraud prevention measures—you can proceed to buy Bitcoin or alternative coins like Ethereum, Solana, or Cardano.
Navigate to the trading dashboard on your exchange platform:
- Search for “Bitcoin” or “BTC”
- Enter the amount of AUD you wish to invest
- Review the estimated BTC quantity based on current market rates
- Click “Buy” to execute the trade instantly
Your purchased crypto will be stored securely in your exchange wallet, with options to transfer it to a private hardware wallet for enhanced security.
Understanding CommBank’s Crypto Transaction Policies
In response to rising concerns about scams and fraud, Commonwealth Bank has implemented specific rules governing cryptocurrency-related transactions. These policies aim to protect customers while maintaining regulatory compliance.
Key Restrictions You Should Know
🔹 $10,000 Monthly Transfer Limit
You’re limited to sending a total of $10,000 per calendar month across all your CommBank accounts to cryptocurrency exchanges. This cap applies cumulatively—even if you have multiple accounts or use different transfer methods.
🔹 24-Hour Payment Hold
All outgoing payments to crypto platforms are subject to a mandatory 24-hour delay. This cooling-off period allows CommBank to monitor for suspicious activity and reduce the risk of irreversible losses from scams.
🔹 Transaction Declines Beyond Limits
Attempting to exceed the monthly cap will result in an automatic decline. You’ll receive an alert via NetBank, email, SMS, or the CommBank mobile app explaining the blockage.
🔹 Withdrawals Are Unrestricted
While deposits face limitations, withdrawing crypto proceeds back into your CommBank account is generally unrestricted—provided the exchange supports it. This makes it easy to cash out profits or rebalance your portfolio.
🔹 Policy Applies Across All Accounts
The $10,000 limit isn't per account—it's a combined total across every account linked to your identity at CBA.
These rules reflect a growing trend among Australian banks to balance innovation with consumer protection in the rapidly evolving digital asset space.
