If you have selected to be paid via Bank Details, you can update your payment details through My Account.
Click on the "profile" section of my account and you'll come across "my bank details" at the bottom. You'll have to sign in again to view or make changes to your payment details. Once updated, click "done" and your new bank details will be saved.
We will not be held responsible if the payment details provided are incorrect, and the payment is successful.
Please note: This is not how you update Rental payment details. Please see here for Rental payment advice.
