In Australia, the International Bank Account Number (IBAN) system is not used for domestic or incoming international transactions. Instead, Commonwealth Bank and all other Australian financial institutions rely on a combination of a Bank State Branch (BSB) code and an account number to uniquely identify an account for both local and overseas fund transfers.

When you need to receive money from overseas, you provide the sender with your BSB and account number, along with a Bank Identifier Code (BIC), also known as a SWIFT code. This combination serves the same purpose as an IBAN by ensuring the funds are routed correctly to your specific account within the Commonwealth Bank network.

Providing details for international payments

If someone is sending funds to your Commonwealth Bank account from another country, provide them with the following details:

  • Your BSB and Account Number: These 9–11 digits uniquely identify your account at your specific branch.
  • The SWIFT/BIC Code: This is a unique identifier for Commonwealth Bank. You can find the official SWIFT/BIC code on the bank’s website or your account documents.
  • Your Full Name and Address: Include your details exactly as they appear on your bank account profile to ensure the funds are cleared without verification delays.
  • Bank Name and Address: Provide the official name, "Commonwealth Bank of Australia," and its head office address if required by the sending institution.

Troubleshooting common issues

MFA or login issues
If you cannot access NetBank to view your BSB and account number, it may be due to an authentication error. Try using the "Forgot login" function. If your NetCode authentication is failing, ensure your phone has a strong signal or contact the bank to verify your mobile number.

Browser or app errors
If the international payment information page is failing to load, clear your browser cache or try an alternative browser. If the issue persists, the digital portal may be undergoing maintenance. Wait a few hours or call customer support to request your SWIFT code and BSB verbally.

Locked account or access issues
If your account is locked and you are expecting an international transfer, this can pause the incoming funds. You must contact the bank to verify your identity and lift any restrictions. Do not provide account details to unknown international senders until you have confirmed the legitimacy of the transaction.

Pro-Tip: Use the "International payment details" feature in NetBank to generate a pre-filled document containing your BSB, account number, and the SWIFT code. This helps avoid manual entry errors when sharing your details with international senders.

Frequently Asked Questions

Why does an overseas sender keep asking me for an IBAN?

International senders are often accustomed to the IBAN system used in Europe and other regions, which is mandatory for transactions in those areas. Since Australia does not use IBANs, they may be confused by your BSB and account number. The system works because the SWIFT/BIC code bridges this gap, informing the sending bank that the account is Australian-based. Your next step is to explain that Australia does not use IBANs and provide the BSB and SWIFT/BIC code instead.

Is my SWIFT/BIC code the same for all my accounts?

Yes, the SWIFT/BIC code is assigned to the bank as an institution, not to your individual account. If you have a savings account and a transaction account, they will both share the same SWIFT/BIC code for Commonwealth Bank, but they will have different BSBs and account numbers. One limitation is that using an outdated or incorrect SWIFT code can cause payment delays. Your next step is to verify the current SWIFT/BIC code for Commonwealth Bank via the official website before sharing it with a sender.
