100% Security Guarantee
With NetBank the safety of your money is 100% guaranteed.
This means we’ll cover any loss should someone make an unauthorised transaction on your account using NetBank – provided you protect your Client number and Password, and immediately notify us of the loss, theft or misuse of your password and of any suspicious activity on your account.
Report suspicious activity on your account by calling 13 2221 option 4 (24 hours a day, 7 days a week).
24/7 transaction monitoring
A dedicated security team monitor NetBank for suspicious activity around the clock to ensure your online banking remains secure.
Commonwealth Bank security staff also work closely with the Australian High Tech Crime Centre (AHTCC) and Australian Federal Police to protect our customers.
NetCode is a free security upgrade that not only protects your money but your identity as well. It is no secret that online banking is a common target for fraud and identity theft. With this in mind, we introduced NetCode protection to help ensure both your financial and personal safety when using NetBank.
When you perform actions within NetBank that are considered ‘high risk’ we will request that you enter a six digit NetCode that we send to you via SMS or the CommBank app. An average NetBank user will receive this request once a month.
Much like strapping on a seatbelt adds an extra couple of seconds to your journey, yet significantly increases your safety levels when driving, NetCode is a minor extra step to help ensure your online banking experience is a safe one.
