Contacting Commonwealth Bank Support
If you require assistance with your banking, Commonwealth Bank provides several ways to get in touch. While many standard queries can be resolved using the CommBank app or NetBank 24/7, you may occasionally need to speak with a human specialist. It is worth noting that while some support lines operate with extended hours, others are limited to standard business times depending on the nature of your request.
For general banking enquiries, the main contact line is typically available from 6am to 10pm (Sydney/Melbourne time), any day of the week. However, specialized teams—such as those handling customer verification, tax status, or remediation—often operate during standard business hours, generally between 8am and 6pm on weekdays. Checking the nature of your query before calling helps ensure you reach the correct team during their active hours.

Step-by-Step Guide: Reaching a Specialist
Following this sequence helps you reach the right department without unnecessary delays.
- Log in to the CommBank app and tap the 'Help' icon to see if your query can be resolved by the virtual assistant or via secure messaging.
- If you must call, use the specific number associated with your issue (e.g., general banking, home loans, or business support) to avoid being transferred or call to the general number 13 22 21.
- Have your client number, and if applicable, your telephone banking PIN ready before you dial.
- If the wait time is high, consider using the 'Message us' feature in the app to leave a query, which allows you to continue with your day while waiting for a response.
Troubleshooting Common Issues
MFA / Login Issues
If you cannot reach support because you cannot log in to verify your identity, the cause is often a delay in receiving your security code. A simple fix is to toggle your phone’s airplane mode to force a network refresh. If the code still fails to arrive, contact the bank using a different method, such as a landline or by visiting a branch, to verify your contact details.
Browser or App Errors
Sometimes the 'Help' or 'Contact' sections in the app may fail to load. This usually happens when the application cache is cluttered or the app requires an update. Try clearing your app cache or updating the software through your app store. If the problem continues, logging in via a desktop browser is a more stable alternative for accessing support links.
Locked Account / ID Issues
Entering your login details incorrectly multiple times will trigger a security lock to protect your account. You cannot resolve this through self-service if your profile is suspended. The fallback action is to call the bank's support line, as they must manually verify your identity before they can restore your digital access.
Pro-Tip: Use the 'Help' icon inside the CommBank app to start a chat rather than calling. The app validates your identity automatically when you are logged in, which saves you the time of answering security questions when you finally reach a human specialist.
Frequently Asked Questions
What is the CBA Osko offer, and does it affect support hours?
Osko is not an "offer," a promotion, or a service you need to sign up for; it is the name for the payment infrastructure (the New Payments Platform) that enables near real-time transfers between Australian bank accounts, 24/7. It does not relate to support hours or contact centre operations. You do not need to contact the bank to "enable" or "get" Osko, as it is standard technology built into your account. If you are having trouble with a fast payment, you can contact general support during their operational hours to trace the transaction.
Can I get 24/7 help for my general banking enquiries?
While the CommBank app and NetBank provide 24/7 digital tools for checking balances, transfers, and basic account maintenance, live human support for general enquiries operates within specific hours, typically 6am to 10pm. If you have an urgent matter outside of these times, such as reporting a lost card or suspicious transaction, those emergency lines remain open 24/7. For less urgent tasks, the secure messaging feature in the app is the best way to leave a request for a specialist to review when they are next available.
