Commonwealth Bank Swift Code – Same for All Branches
The Commonwealth Bank of Australia uses a single SWIFT code for all its branches nationwide, making international transfers straightforward for customers regardless of their location. This guide covers the official SWIFT/BIC code, how it applies to different branches, and the additional details required for sending or receiving money internationally.
When sending money to or from Australia, the SWIFT code serves as the identifying marker for Commonwealth Bank in the global financial network. Understanding this code helps ensure transfers reach their intended destination without unnecessary delays or complications.
What is the Commonwealth Bank SWIFT Code?
The official SWIFT/BIC code for Commonwealth Bank of Australia is CTBAAU2S. When used with the optional three-character branch identifier, it appears as CTBAAU2SXXX. This code follows the international ISO 9362 standard format used to identify financial institutions in wire transfer messages.

How the SWIFT Code Breaks Down
Each section of the CTBAAU2SXXX code carries specific meaning under the ISO 9362 standard. The bank code CTBA identifies Commonwealth Bank of Australia. The country code AU designates Australia as the nation. The location code 2S refers to the Sydney head office, where the primary operations are centered. The branch code XXX indicates the head office or primary branch, meaning no specific branch identifier is needed for standard transfers.
Using the full 11-character code CTBAAU2SXXX provides maximum precision, though the 8-character version CTBAAU2S typically suffices for most international transfers. According to Wise, both formats are widely accepted by financial institutions.

Is the SWIFT Code the Same for All Branches of Commonwealth Bank?
Yes. The CTBAAU2SXXX code applies uniformly to the Commonwealth Bank head office and all Australian branches. This means customers in Sydney, Melbourne, Perth, Brisbane, or any other location use the same SWIFT code for international transfers. The universal code simplifies the process, as no city-specific or branch-specific code needs to be identified.
SWIFT Code for Sydney
As the location of the head office, Sydney uses CTBAAU2SXXX as the primary reference point for the code. The TheSWIFTCodes directory confirms Sydney as the registered location for this code designation. Transfers to Sydney-based accounts use exactly the same code as transfers to any other Australian branch.
SWIFT Code for Melbourne
Melbourne customers should use CTBAAU2SXXX for all international transfers. No separate Melbourne-specific code exists for standard transactions. One source notes a variant code involving a Melbourne Group Treasury Centre, but this represents an internal operational identifier rather than a standard customer-facing code and lacks corroboration from major sources.
SWIFT Code for Perth and Brisbane
Perth and Brisbane branches also operate under the same universal CTBAAU2SXXX code. The Transfez database confirms that branch-specific codes are not required for standard international transfers to these cities. This uniformity reflects how major Australian banks structure their SWIFT presence as a single national entity rather than separate regional divisions.
While rare service-specific variants may appear in certain transfer platforms, the standard and officially recognized code remains CTBAAU2SXXX for all customer-facing international transfers to Commonwealth Bank accounts in Australia.
What Other Details Are Needed with the Commonwealth Bank SWIFT Code?
The SWIFT code alone does not complete an international transfer. Additional banking identifiers are required to route funds to the correct account. These requirements differ from systems used in Europe and other regions that rely on IBAN numbers.
BSB Number and Account Number
For domestic Australian banking, the BSB (Bank State Branch) number identifies the specific branch where an account is held. Combined with the account number, this uniquely identifies any Commonwealth Bank account within the Australian banking system. When sending international transfers to a CommBank account, the recipient typically provides their BSB number (six digits) and account number (typically 6-9 digits). The CommBank international transfer page outlines these requirements clearly for customers initiating overseas payments.
Why Australia Does Not Use IBAN
The International Bank Account Number (IBAN) system is used primarily in Europe, the Middle East, and parts of Africa to standardize cross-border payments. Australia never adopted the IBAN format, relying instead on its established BSB and account number system. This means international senders to Commonwealth Bank accounts do not need to obtain or provide an IBAN. XE currency services confirm that IBAN is not required for Australian transfers.
When initiating an international wire to a Commonwealth Bank account, ensure you have the recipient’s full name, account number, BSB code (six digits), and the SWIFT code CTBAAU2SXXX. Some services may also request the bank’s registered address for verification purposes.
What is the Commonwealth Bank SWIFT Code and Address?
The official registered address associated with Commonwealth Bank’s SWIFT code is Floor 1, Commonwealth Bank Place, South 11 Harbour Street, Sydney, NSW 2000, Australia. This address, listed consistently across Remitly, RemitFinder, and other official directories, serves as the reference point for the CTBAAU2SXXX code even when transfers target branches in other cities.
The Sydney head office address may be required by some international banks or transfer services as a final verification step. This address corresponds to Commonwealth Bank Place, located in Sydney’s central business district near the waterfront.

How to Use the SWIFT Code for International Transfers
Whether sending money to or receiving money from overseas, the SWIFT code CTBAAU2SXXX plays a central role in routing the transfer correctly through the international banking network.
Sending Money to Commonwealth Bank
When transferring funds to a Commonwealth Bank account from abroad, provide your bank or transfer service with the recipient’s full details.

The CommBank receiving money guide outlines these requirements clearly.
Receiving Money from Overseas
If expecting an international transfer to your Commonwealth Bank account, you will need to provide the sender with your account details. This includes your BSB number (found in CommBank app or NetBank), your account number, the SWIFT code CTBAAU2SXXX, and your full name. The sender’s bank will use this information to route the funds through the SWIFT network to your account.

What’s Confirmed and What Remains Unclear About the Commonwealth Bank SWIFT Code
When dealing with financial institution codes, clarity about what is definitively established versus what carries uncertainty helps ensure accurate transfers. The following assessment distinguishes between confirmed information and areas that may require additional verification.
| Confirmed Information | Areas of Uncertainty |
|---|---|
| CTBAAU2SXXX is the primary SWIFT code for Commonwealth Bank, confirmed by official CommBank sources and multiple third-party directories | Occasional service-specific variants noted on certain platforms (such as Wise or other transfer services) may reflect internal routing rather than customer-facing codes |

| Australia does not use IBAN numbers; the SWIFT code works alongside BSB and account number | Some specialized services may request additional identifiers not commonly needed; verification with the specific service provider remains advisable |
| The registered address (Floor 1, Commonwealth Bank Place, South 11 Harbour Street, Sydney, NSW 2000) is consistent across all major sources | Transfer fees, processing times, and specific service requirements vary by provider and may change without immediate updates in public directories |
Understanding SWIFT Codes and International Banking
The SWIFT network, operated by the Society for Worldwide Interbank Financial Telecommunication, serves as the global messaging system that enables secure communication between financial institutions. When a bank initiates an international wire transfer, it sends a SWIFT message containing the recipient bank’s SWIFT/BIC code, which acts like a postal address in the global banking system.
BIC stands for Bank Identifier Code, and it serves the same function as a SWIFT code. Both terms refer to the standardized eight-to-eleven-character code that uniquely identifies a bank in international transactions. The term SWIFT evolved from the organization’s name but has become the commonly used term in banking contexts.
For Commonwealth Bank customers, understanding that CTBAAU2SXXX represents their bank in the global network simplifies international transactions. Unlike smaller institutions that may have different codes for different branches, major banks like Commonwealth Bank typically maintain a single national code for simplicity and consistency.
Official Sources and References
The primary authoritative source for Commonwealth Bank’s SWIFT code remains the bank’s own official website. CommBank’s support pages on bank identification codes and international money transfers provide customer-facing guidance aligned with the code information.
Third-party financial platforms including Wise and XE maintain updated databases of banking codes, with their listings for Commonwealth Bank confirming CTBAAU2SXXX as the current active code. These services often serve as practical references for customers comparing transfer options, though the bank’s own channels should be consulted for the most authoritative guidance.
Key Takeaways
The Commonwealth Bank SWIFT code CTBAAU2SXXX covers all Australian branches, including those in Sydney, Melbourne, Perth, and Brisbane. Customers do not need different codes for different cities—the universal code handles routing for the entire institution.
