Managing your transaction limits

Daily transaction limits are a security measure designed to protect your account by restricting the total value of transfers you can make within a 24-hour period. While these limits help reduce the potential impact of unauthorized access, they can occasionally prevent you from completing large, legitimate payments.

You can adjust these limits directly through the CommBank app or NetBank. Changing your limit typically takes effect immediately, allowing you to proceed with your transaction once the update is confirmed. It is generally recommended to keep your limits low for everyday use and only increase them when you have a planned large purchase.

Steps to update your daily limit

If you need to change your transfer ceiling, the process follows a standard security workflow to ensure the request is authorized by the account holder.

  • Log in to the app: Open the CommBank app and authenticate your session.
  • Navigate to Settings: Tap the 'Settings' tab or your profile icon to view account options.
  • Locate Payment Limits: Select 'Payment limits'.
  • Adjust and Confirm: Use the slider or input field to set your new limit. You will likely be prompted to verify this change using your security PIN or biometric authentication.

Troubleshooting common issues

Technical snags can occasionally prevent you from saving new limit settings. Here is how to handle the most frequent problems.

  • MFA or login issues
    Cause: Often occurs if your registered mobile number is out of date or if network latency prevents the receipt of your security code.
    Fix: Verify your contact details in your profile settings and ensure you have a stable network connection.
    Fallback: Contact the bank's support line to verify your security profile manually.
  • App or browser errors
    Cause: Outdated app versions or browser cache issues can interfere with the confirmation prompt when saving new limits.
    Fix: Update your CommBank app to the latest version via the app store or clear your browser cache if using NetBank.
    Fallback: Try using a different browser or device to complete the adjustment.
  • Locked account access
    Cause: Repeated attempts to change limits with incorrect credentials can trigger a temporary security lock on your account settings.
    Fix: Wait for the lock period to expire, or use the online password recovery tool to reset your credentials.
    Fallback: Visit a local branch with identification to have your account access restored in person.

Pro-Tip: Before initiating a large payment, check your current limit in the app to see if it covers the intended amount. Adjusting your limit hours before you need to make the payment avoids the scenario where a transaction is declined at the checkout, saving you time and preventing potential delays.

Frequently Asked Questions

Q: Why does the bank restrict how high I can set my daily transfer limit?
The bank applies an upper threshold to daily transaction limits to manage risk and protect your funds from potential fraud. If a bad actor were to gain access to your account, a pre-set limit prevents them from draining your entire balance in a single transaction. If you need to make a one-off payment that exceeds your maximum allowed limit, you will typically need to call the bank's support team to request a temporary exception or discuss alternative payment methods, such as a bank cheque.

Q: Will my increased limit apply to all types of payments?
Generally, your daily limit applies to the total value of funds transferred out of your account via standard transfers, such as NPP or Osko payments. However, specific types of transactions—like BPAY, international transfers, or branch withdrawals—may operate under different limit structures. Always verify which categories your new limit covers within the app settings; if you find a payment is still declined, check if it falls under a separate category that requires its own adjustment.
