Understanding Bankwest and Commonwealth Bank Ownership
Bankwest is a wholly-owned subsidiary of the Commonwealth Bank of Australia (CBA). The CBA Group formally acquired Bankwest in 2008, meaning Bankwest operates under the broader corporate umbrella and regulatory framework of the Commonwealth Bank. Despite this ownership structure, Bankwest has historically maintained its own distinct brand identity, product offerings, and separate digital banking platforms for its customer base.
In 2024, Bankwest announced its transition into a fully digital bank, resulting in the permanent closure of its physical branch network. As a consequence of this operational shift, customers who require face-to-face banking services must either utilize third-party physical access points or formally transition their everyday banking accounts directly to the Commonwealth Bank to access CBA's national branch network.

Troubleshooting Digital Access and Transitions
If you encounter technical errors while managing your digital profile or transitioning between the two banks, review these standard resolution paths:
- MFA / Login Issues: If you are not receiving SMS security codes to authorize an account transition, an outdated phone number or network congestion is the likely cause. Ensure your device has mobile reception and wait 60 seconds before requesting a new code. If delivery continues to fail, contact Bankwest phone support to authenticate verbally and update your contact details.
- Browser or App Errors: When attempting to load secure messaging or transfer screens, the Bankwest app may time out or display a system error due to corrupted cache data. Force close the application and clear its cache within your device settings. If the error persists, log in through the desktop online banking portal as a reliable fallback.
- Locked Account / ID: Entering an incorrect password or Personal Access Number (PAN) multiple times will trigger an automated security lock on your profile, blocking all transfers. You cannot bypass this security measure online. You must call Bankwest customer service to complete a verbal identity check and reset your digital access credentials.
Pro-Tip: If you are migrating your primary banking from Bankwest to CBA, leave your Bankwest account open with a small buffer balance for at least one full 30-day billing cycle. This allows quarterly direct debits or delayed merchant charges to clear successfully, protecting your credit file from missed payments while you finalize updating your new payment details.
Frequently Asked Questions
Can I use a Commonwealth Bank branch to manage my Bankwest account?
Although the Commonwealth Bank owns Bankwest, the two institutions operate on completely separate core banking infrastructures. This separation means CBA branch tellers cannot look up your Bankwest account profile to process deposits, withdrawals, or administrative changes. If you hold a Bankwest account and need to deposit physical cash, you must visit a participating Australia Post outlet to use the Bank@Post service.
Do Bankwest and CBA accounts share the same BSB routing numbers?
No, Bankwest retains its own unique Bank State Branch (BSB) prefixes, which route payments through its specific digital ledgers, distinct from CBA's routing numbers. If you provide a payer with your Bankwest account number but incorrectly supply a generic CBA BSB, the transaction will bounce back to the sender due to mismatched routing. Always copy the exact BSB displayed on the account summary screen inside your Bankwest App.
