Our Online Guardian fraud detection system monitors your online banking activity, learns your usual functions and identifies unusual activity. You can learn more about it in the Online Guardian section.

Our online banking fraud team

This team spends their time analysing online banking activity, backing up our Online Guardian service.

If you get a call from our online banking fraud team, they’ve been analysing transaction/s that may look suspicious, and will need confirmation from you that the transaction/s on your account/s were made or authorised by you.

What they won’t ask

Our online banking fraud team will never ask you for confirmation of your security details or password. These should not be disclosed to anyone.

Automatic Westpac One logout

If your Westpac One online banking session remains inactive for 10 minutes, you’ll be automatically ‘timed out’.

You should also click on the log out button when you’ve finished your online banking session, so that:

  • all pages you visited are removed from the browser's cache
  • no one else can click on the ‘back’ button to see your account details if they get on your computer or device.

Security email and text alerts

It’s a great idea to set up security email and text alerts (they’re free), to keep track of your online banking activity, bank account and credit card information. You can only set up alerts in Original Online Banking, but they’ll still work in response to your activity on Westpac One.

They can tell you:

  • when your online banking password changes, or when a login is made to your online banking
  • when a change is made to someone you pay online or a new person is added
  • when a payment is planned from one of your accounts that is over an amount you choose. This excludes transfers between your accounts and International Payments
  •  automatic alerts – triggered by certain changes to your online banking or alert settings. These cannot be turned off.

Other email & text alerts
