Head Office / Corporate Office Update
The older version of this page listed NAB’s corporate address as 800 Bourke Street, Docklands, VIC 3008, Australia. NAB’s current official head office and registered office listing uses National Australia Bank Limited, Level 28, 395 Bourke Street, Melbourne VIC 3000, Australia.
The old page also listed +61 3 8641 9083 as the corporate office phone number. That number is better labeled as an overseas personal banking support number. For NAB head office or registered office contact, NAB lists 1300 889 398 within Australia and +61 3 8615 3064 from outside Australia.
For routine banking, account, card, loan, business banking, online banking, fraud, or complaint issues, customers should usually start with the support route tied to their account rather than sending everything to the head office.
How to Contact NAB About a Complaint
For most NAB complaints, start with the support route connected to your account or service. NAB customers can lodge complaints through a branch, NAB Messaging in internet banking, the NAB app, the official feedback form, or by calling the relevant support number.

- The last four digits of the account, card, loan, or facility involved
- The transaction date, amount, merchant, transfer, branch, or account activity involved

Do not post account numbers, card numbers, passwords, PINs, one-time codes, tax file numbers, driver licence details, passport details, wire instructions, home addresses, business banking credentials, or private financial screenshots in public reviews or comment sections.
How to Escalate a NAB Complaint
Start with NAB directly and ask for a complaint reference number. NAB says it will try to resolve complaints quickly and may pass unresolved complaints to a specialist team or case manager.
If the complaint is not resolved, ask NAB for a written response explaining the outcome. Keep copies of all messages, statements, screenshots, letters, branch notes, payment confirmations, dispute records, and fraud reports.
If NAB does not resolve the complaint within the required timeframe, or if you are not satisfied with NAB’s response, you may be able to contact the Australian Financial Complaints Authority. AFCA is an external dispute resolution service for eligible financial complaints in Australia.
NAB Registered Office and Legal Notices
NAB’s registered office is National Australia Bank Limited, Level 28, 395 Bourke Street, Melbourne VIC 3000, Australia.

If your issue involves a transaction you do not recognize, check the merchant details in the NAB app or internet banking. Some merchants bill under a different business name. If you still do not recognize the transaction, contact NAB promptly.

Fraud, Scams, Phishing, and Fake NAB Support Numbers
Bank customers are frequent targets for phishing emails, fake text messages, spoofed phone calls, remote-access scams, investment scams, invoice scams, and fake bank support numbers.
NAB says suspicious emails can be forwarded to ph***@*****om.au and suspicious text messages can be forwarded to 0476 220 003. If your online security has been compromised or you are concerned about a transaction, contact NAB immediately through the NAB app or the official phone numbers.
Do not share passwords, PINs, one-time codes, full card numbers, full account numbers, business banking credentials, remote access, wire instructions, cryptocurrency payments, or gift card payments with someone who contacts you unexpectedly.
