An overdraw fee is charged when your Commonwealth Bank transaction account balance falls below zero and remains negative at the end of the day. This typically happens when payments, such as direct debits or card purchases, exceed the available funds in your account at the time of processing.

The overdraw feature is designed to help prevent important payments from being declined, but it is not intended to be used as a source of ongoing credit. By understanding how these charges occur and monitoring your balance, you can better manage your finances and avoid unnecessary costs.

Methods Monitored via CommBank app and NetBank.
Processing Time Fee is typically charged if the balance is negative at midnight (AEST).

Key Requirements Maintain a positive balance by midnight on the day the payment is due.

Steps to manage and avoid fees

To stay on top of your account balance and minimize the risk of overdraw fees, you can follow these practical steps:

  • Set up real-time alerts: Use the CommBank app to turn on notifications for when your balance is low. This provides an early warning if your funds are approaching zero.
  • Check your account daily: Regularly log in to the CommBank app or NetBank to review your "Available balance." Remember that some payments, like bill debits, may process later in the day.
  • Bring your account back to positive: If you notice your balance is negative, transfer funds into the account before midnight (AEST). Bringing the balance to a positive state before this cutoff generally helps you avoid the $15 overdraw fee.
  • Manage overdraw preferences: You can choose to switch off the overdraw feature entirely via the "Manage" section in your account settings. Note that if you do this, payments exceeding your balance will be declined, which may incur a separate dishonour fee.

Troubleshooting common issues

MFA or login issues
If you are unable to check your balance due to login difficulties, try refreshing the CommBank app. If your multi-factor authentication (MFA) is failing, ensure your phone has a stable connection and your registered contact details are accurate. If the issue persists, contact the bank's support team for help regaining access.

Browser or app errors
If the app or website is not displaying your correct balance, it may be a temporary display delay. Clear your browser cache or check if there is an update available for your app. If the balance remains unchanged after trying these steps, call the bank to confirm your actual account status.

Locked account or access issues
If your account is locked following a period of being overdrawn, you will not be able to perform transfers to clear the debt online. This is a security measure. You will need to contact Commonwealth Bank support or visit a branch to verify your identity and discuss options to restore your account functionality.

Pro-Tip: Use the "Simple Balance" feature on your CommBank app home screen. This allows you to check your available funds instantly without needing to fully log in, making it easier to verify your balance before making purchases.

Frequently Asked Questions

Why was I charged a fee if my account was only negative for a few hours?

The system checks your account balance at midnight (AEST). If your account is negative at that specific time, a $15 overdraw fee is typically triggered, regardless of how long the account was overdrawn during the day. One limitation is that even if you deposit funds later that same night, if it is after the midnight threshold, the fee may still be applied. Your next step is to ensure any transfers to cover a shortfall are completed well before the midnight deadline.

Can I have an overdraw fee waived?

If the overdraw was an isolated incident and you have a history of maintaining a positive balance, the bank may occasionally consider a one-off reversal. This is at the bank's discretion and is not a guaranteed policy. One exception is if the overdraw occurred due to a bank error or an unauthorized transaction. Your next step is to contact Commonwealth Bank customer service to explain the situation politely and ask if they can review the fee.
