Beware of fraud

Remember that CommBank will never send you a link asking you to enter your NetBank client number and password, card number or any other sensitive information.


If you think your account or identity might have been compromised, change your passwords and PINs straight away. Always choose long passphrases instead of short passwords and never re-use the same password for different services.


Review any request for your personal details with a critical eye. It’s completely okay to reject or ignore any requests. Criminals will often try to create a false sense of urgency.


If you (or someone you know) is a CommBank customer and has been targeted or lost money as a result of fraud, call us immediately 24/7 on 13 2221.

Protecting yourself from fraud

  • What to look for

    • Never click on any links in an email from an unknown or untrusted source.
    • Never go to an online banking website or another log on page from a link in an email.
    • Use your bank’s official app and log out after every session.
    • Stop and think before you share any personal or financial information about you, your friends or family.
    • If you’ve been shopping online, keep an eye on your transaction history and report anything suspicious as soon as possible.
    • Avoid using public networks, such as free Wi-Fi networks. Never shop or bank online using public Wi-Fi.
    • Navigate directly to an online store using your web browser, rather than by clicking an email or social media link.
    • Secure your phone with a strong, secret PIN number or passcode, or with fingerprint detection.
    • Enable multi-factor authentication to secure your online accounts (including email) where available.
    • Keep statements, receipts, tax returns and other documents showing your personal financial information safe. If you throw them away, shred them first.
    • Keep an eye on the CommBank app as we’ll send you security messages when we need you to review suspicious activity. The best way to stay up-to-date is to turn on Push Notifications in the CommBank app.
