In an Australian banking first, NameCheck will prompt you if the account details on a first-time payment don’t look right. This can help protect you from business email compromise scams and mistaken payments.
Received a call from us? CallerCheck allows you to verify whether a caller claiming to be from CommBank is legitimate, by triggering a security notification in your CommBank app.
CustomerCheck allows CommBank staff to securely identify you when you visit a branch or meet with a specialist. They'll send a notification to your CommBank app to confirm they're dealing with the right person.
In addition, we accept over the counter deposits into personal accounts from CommBank customers only.
Our systems will monitor for unusual activity. We may be in touch with you if we detect something suspicious on your account, so make sure your contact details are up-to-date. We also encourage you to monitor your transactions.
Turn on your notifications in the CommBank app to receive alerts so you can act quickly if necessary.
We’ll protect you from losses due to unauthorised transactions on personal and business accounts when you take the necessary steps to stay safe online.

Behavioural information is a way we track patterns in how you interact with your device - things like how you hold your phone, tap on the screen, or type.
Behavioural information involves measuring and tracking patterns in the way an individual moves, behaves, or interacts with their device. This can range from how a person holds and moves a device, such as a mobile phone, to how their fingers tap the screen and the force of their taps.
CommBank is collecting behavioural information about the way you interact with your devices while using the CommBank app, NetBank and CommBiz. This includes information about how you interact with your devices such as typing speed, keystroke pattens and mouse movement to help identify potential fraud.
CommBank collects behavioural information to help detect suspicious cyber activity and financial crime to combat fraud and scams, such as identity theft.
A customer's behavioural information allows CommBank to help identify habits and patterns of how that customer typically interacts with their device. Deviations from these habits and patterns may be a sign a customer’s accounts have been compromised or that someone else is using their devices.
The way that you interact with our digital platforms is used to help identify if you are truly, you or if a third party is in control of your banking. All behavioural information we collect is held by our trusted third party in a de-identified form to help maintain your privacy.
Your behavioural information will only be collected when you are using the CommBank app, NetBank and CommBiz.
If you don’t consent to this information being collected, you won’t be able to use these platforms. We can support you to remove your NetBank ID if required.
Tips to keep you CommBank Safe
Our CommBank Safe video series shares some of our top tips on how you can stay one step ahead of the latest cyber threats, scams and fraud.
There may be a time when we will reach out to you to confirm information on your account or your identity.
Having accurate and up-to-date details is part of our ‘Know Your Customer (KYC) requirements. It also helps us protect you from fraud, as we can contact you immediately if we detect any suspicious activity.
If you’re ever concerned whether the person you’re speaking to is legitimately from CommBank, you can use the CallerCheck feature in the CommBank app to verify your caller’s identity.
Regardless of whether the caller has been identified, we will never ask you to transfer funds, share your screen or reveal your passwords.
CommBank and Telstra join forces
Scam Indicator is designed to detect certain high-risk scam situations in real-time to help protect joint CommBank and Telstra customers. Developed in partnership with Quantium Telstra, it allows us to check if the customer is on a phone call when transferring large amounts of money – the prime indicator that a scam is occurring – so we can try and contact you or put in additional security checks.
To protect privacy, we‘ll only be able to access specific data points relating to scam prevention, and we won’t have access to any other underlying customer data.
