If you are dissatisfied with a product or service provided by National Australia Bank (NAB), you have the right to lodge a formal complaint. The bank operates an internal dispute resolution process designed to address issues through frontline staff, or through specialist teams if a resolution is not found immediately. Initiating a complaint through the correct channels ensures your feedback is tracked, assigned a reference number, and directed to the team equipped to handle your specific situation.
You can lodge a complaint yourself or authorize someone else to act on your behalf, such as a financial counsellor or family member. Whether you choose to speak with staff in a branch, use the online form, or write to the dedicated resolution team, the bank follows a structured process to investigate and respond to your concerns. Understanding this pathway helps you manage expectations regarding timelines and potential outcomes.

Step-by-Step Guide to Lodging a Complaint
- Collect your supporting documentation, such as transaction records, correspondence, or account details that relate to your issue.
- Contact the bank via your preferred channel: call 13 22 65 for personal banking or 13 10 12 for business, or use the online 'Feedback & Complaints' form.
- Clearly state the nature of your concern and the specific outcome you are seeking, and request a complaint reference number for your records.
- Allow the frontline team or assigned Case Manager to investigate the matter; they will typically update you if the issue requires a more detailed review.
- Review the final response from the bank; if the outcome does not address your concerns, request an internal senior review or contact the Customer Advocate.
- If the internal process remains unresolved, you may choose to escalate the matter to the Australian Financial Complaints Authority (AFCA).
Troubleshooting Common Access Issues
1. MFA / Login Issues
- Cause: You cannot submit your complaint online because your multi-factor authentication (MFA) token fails to send during the login attempt.
- Simple Fix: If you are locked out of digital channels, use the phone-based complaint line (13 22 65) to lodge your grievance without needing to log in.
- Fallback Action: Visit a local NAB branch where staff can verify your identity and lodge the complaint on your behalf.
2. Browser or App Errors
- Cause: The online feedback form fails to submit or freezes, often due to an unstable internet connection or an outdated browser version.
- Simple Fix: Try submitting the form using a different web browser or switch to a private (incognito) window to avoid cached data errors.
- Fallback Action: Use the mail option by printing the form or writing a letter to 'NAB Resolve, Reply Paid 2870, Melbourne VIC 8060'.
3. Locked Account / ID / Access Issues
- Cause: You cannot access your account history to retrieve the reference number required for your complaint due to a temporary security block.
- Simple Fix: Call general customer support to resolve the account block first, or lodge the complaint without the specific reference number by providing the transaction date instead.
- Fallback Action: Contact the financial hardship or general support line for assistance in accessing the necessary account information.
Pro-Tip: Always request and record your complaint reference number the moment you lodge your feedback. When following up, referencing this specific number allows the Case Manager to pull your file and view the history of previous interactions, which prevents the need for you to repeat your story.
Frequently Asked Questions
Q: What should I do if my complaint is not resolved within the promised timeframe?
The bank aims to resolve standard complaints within 30 days. If your issue is complex or involves circumstances outside their control, they may send you an 'Internal Dispute Resolution (IDR) delay notification' explaining the hold-up and providing a new estimated timeframe. If you have not received an update or a final response after this period, you should write to the bank to request an escalation to the Customer Advocate. If this further review remains unsatisfactory, you have the right to take your complaint to AFCA.
Q: Is there any benefit to using an external dispute resolution service?
AFCA is an independent body that handles complaints when the bank’s internal resolution process has been exhausted. You might choose to contact them if you believe the bank's final response was unfair or if you have reached a deadlock. The benefit of AFCA is that their decisions can be binding on the bank. Before going to AFCA, ensure you have received a final response letter from NAB or have waited the required 30 days, as AFCA will generally ask if you have given the bank a reasonable opportunity to resolve the issue first.
