Am I protected against fraudulent transactions?

When you take the necessary steps to stay safe online and protect your device from theft, you're covered for fraudulent transactions under the ePayments Code for digital banking.

For more information about the ePayments code, please see section 10 of the Terms & Conditions.

While we take proactive steps to fight fraud, there are many steps you can take to help us stop fraudsters and stop scammers in their tracks. Check out our online security checklist and dedicated scams hub for loads of practical tips and information.

How can I keep track of my account activity?

You can set up SMS notifications to let you know when there’s been activity on your account. This includes an SMS when:

  • Your account is running low on funds.
  • Your card has been used.
  • A scheduled transfer or bill has been paid.
  • Your password has been changed.
  • When you’ve been paid, and much more.

You can set up notifications in online banking and pick and choose which notifications you’d like.
