Understanding the Bankwest and CBA Relationship

Customers often wonder how Bankwest fits into the broader Australian banking landscape, particularly its connection to the Commonwealth Bank (CBA). Bankwest is a fully owned subsidiary of CBA. While it operates under its own distinct brand identity and management structure, it relies on the overarching financial backing and banking license of the Commonwealth Bank Group.

For daily banking, this ownership structure means your funds are managed under a secure, major-bank framework. However, the two banks function separately at the customer level. Bankwest is currently transitioning to a digital-focused model, meaning customer service, app experiences, and account management are handled entirely distinctly from CBA’s retail network.

Key Banking Details Under the Subsidiary Structure

Category Details
Ownership Status Fully owned subsidiary of the Commonwealth Bank Group.
Banking License Operates under CBA's Authorised Deposit-taking Institution (ADI) license.
Account Management Handled entirely via the Bankwest App, online portal, or phone support.
Physical Banking Bank@Post via Australia Post is the primary method for cash transactions.

How to Access and Manage Your Bankwest Digital Account

 

Frequently Asked Questions

Can I use a Commonwealth Bank branch for my Bankwest account?

Even though Bankwest is part of the Commonwealth Bank Group, they operate on separate retail networks. If you walk into a CBA branch to deposit cash, the tellers generally won't be able to pull up your Bankwest account details or process the transaction. The main exception is using CBA-branded ATMs, which Bankwest customers can use without incurring a fee. For over-the-counter cash deposits or withdrawals, check the locator tool in your app to find the nearest participating Australia Post office (Bank@Post).

Are my deposits covered separately if I have accounts with both banks?

The Australian Government’s Financial Claims Scheme (FCS) protects deposits up to $250,000 per person, per Authorised Deposit-taking Institution (ADI). Because Bankwest operates under CBA’s ADI license rather than holding its own, the $250,000 protection limit applies to your combined total across both brands. If you hold significant savings in both institutions that collectively exceed this cap, you might want to review your account structures or consult a financial advisor regarding deposit protection limits.

Will the Bankwest app eventually merge into the CommBank app?

CBA has structured Bankwest to serve as a distinct digital banking brand with its own unique features and interface. Because of this, their IT platforms and mobile applications are built and maintained separately. There are no current provisions allowing you to internally move funds between a CBA account and a Bankwest account without initiating a standard external bank transfer. Continue using the dedicated Bankwest app for your accounts and ensure your device settings allow for automatic updates to keep your banking secure.
