Preparing for Your First NetBank Session

Entering Your Digital Banking Workspace

  1. To begin, always type the official address, commbank.com.au or netbank.com.au, directly into your web browser. Never click on links in emails or text messages when trying to access your online account.
  2. On the NetBank logon page, carefully enter your unique Client Number and your confidential Password into the designated fields.
  3. A prompt will be sent to your CommBank app for approval. Open the app and confirm the logon attempt by selecting 'Yes, this was me'. If you don't receive a push notification, open the app directly and look for the authentication request.
  4. For quicker access on your personal device, you may have the option to tick 'Trust this browser' during the approval step in the app. This can reduce how often you need to confirm future logons from that specific browser.

Unlocking Your Financial Toolkit in NetBank

When Digital Access Becomes a Challenge

⚠️ Forgot Client Number or Password

Cause: Unable to recall login credentials.

Solution: We know being locked out is stressful. If you've forgotten your Client Number or Password, go to the NetBank logon page and click 'Get help logging on', then 'Retrieve NetBank logon details'. You'll need to enter your card number and PIN, then select 'I need to reset my NetBank password'. CommBank will send a NetCode SMS to your registered mobile. Enter this code, and you'll see your Client Number and can then set a new password. If you don't have a CommBank card, don't know your PIN, or your card is not activated, please call CommBank on 13 2221 for assistance.

⚠️ CommBank App Logon Approval Not Appearing (MFA Issue)

Cause: The Multi-Factor Authentication (MFA) notification isn't showing in the app or is not allowing login.

Solution: First, ensure you have the CommBank app installed and that you've successfully logged into it at least once using your NetBank credentials. Next, verify that push notifications are enabled for the CommBank app in your phone's settings. If you still don't receive the notification, open the CommBank app directly, and the approval message should appear on the home screen. Restarting the app or your web browser, checking your internet connection, updating the app, or clearing its cache can often resolve these issues. If problems persist, try uninstalling and reinstalling the app. If you receive a logon notification that wasn't you, select 'No, it wasn't me' in the app to block the attempt and secure your account.

⚠️ General Login Errors

Cause: Unspecified issues preventing access.

Solution: Sometimes, a simple refresh of your browser or restarting the CommBank app can fix minor glitches. Confirm your internet connection is stable and try temporarily disabling any Virtual Private Networks (VPNs) as they can sometimes interfere with banking sessions. Ensure your browser and the CommBank app are updated to their latest versions. If all else fails, reaching out to customer support is the quickest path to resolution.

Your Top NetBank Inquiries Answered

Q: How do I register for NetBank if I'm a new customer or haven't used it before?

If you're an existing CommBank customer and have a card, PIN, and registered mobile phone, you can register for NetBank online. Visit commbank.com.au/digital-banking/netbank.html and select 'Register for NetBank'. You'll need to follow the prompts, which typically involve entering your card number and PIN, verifying via NetCode SMS, and creating a password. If you don't bank with CommBank yet, you can open an Everyday account, and you'll be automatically registered for NetBank.

Q: What is my CommBank Client Number and where can I find it?

Your Client Number is a unique identifier for your NetBank account. It's provided to you upon registration. If you've forgotten it, you can often find it on the back of your physical CommBank card. Alternatively, within the CommBank app, you can usually locate it in your profile section. On the NetBank logon page, there's also an option under 'Get help logging on' to 'Find client number'.

Q: Can I use the CommBank app or NetBank when I am traveling overseas?

Yes, both the CommBank app and NetBank are accessible overseas. However, to ensure smooth access and security approvals (especially for NetCode SMS or app notifications), it's highly recommended to enable app push notifications for MFA before traveling. If you encounter issues or need urgent assistance while abroad, you can contact CommBank's international support line.

Q: What should I do if I receive a security notification for a login I didn't make?

If you receive an authentication notification from the CommBank app for a NetBank logon attempt that you did not initiate, immediately open the app and select 'No, it wasn't me'. This action will block the fraudulent attempt and guide you through steps to change your NetBank password, helping to secure your account from unauthorized access.
