Transaction assurance

We've invested in world class security systems and services to make sure your accounts stay safe when you bank online.

This investment means we can provide our NAB Internet Banking customers with an assurance that they won’t be held responsible for an unauthorised transaction if one were to occur on their account if the customer has complied with our Internet Banking Terms and Conditions of Use.

Contact NAB’s Internet & SMS Banking Support Team on 1300 651 656. The support hours are located on our Contact us page.

Alternatively, if you are a NAB Internet Banking customer, you can send a secure message to us through our Internet Banking message service.
