Commonwealth Bank of Australia: No BSB for International Payments—Use SWIFT

Commonwealth Bank of Australia (CommBank) doesn't use a single BSB (Bank State Branch) for international routing. BSBs are 6-digit codes identifying specific branches within Australia's domestic clearing system (BECS). For inbound international payments, you need:

Required Information

• SWIFT/BIC: CTBAAU2S (CommBank's primary SWIFT)
• Recipient's full name and account number (BSB + account number, or just account number for some products)
• Branch address (optional but helpful)
• Recipient's residential address (for compliance)

Domestic vs. International

Domestic (within AU): BSB (e.g., 062-001 for Sydney CBD) + Account Number. 6 digits: 2 bank (06=CommBank) + 4 branch.

International: SWIFT + Account details. The sender's bank routes via correspondent banking; CommBank's treasury handles final credit to the branch/account.

Common Mistakes

• Using a BSB alone for international wires—will fail or delay.
• Confusing SWIFT (CTBAAU2S) with BSB.
• Omitting intermediary bank details if sender's bank requires them (rare for major currencies).

Pro Tip

Ask the recipient for their "International Bank Account Details" from CommBank's app/online banking—it generates a PDF with SWIFT, account, branch, and intermediary info tailored to the sender's country/currency.
