Can I have multiple Agreements, and how do I cancel a previous one?

You are only able to have one PayTo agreement linked to your account.

To set up a new PayTo agreement, you will have to cancel your current agreement through your banking app. After this has been done, you can then set up a new agreement.
It may take up to 30 minutes for your app to refresh. Once refreshed, you can set up a new agreement in the PayTo section.

• You’ll need to access your banking app. If your bank is listed below, follow these steps:
  
  ANZ- Go to the Payments tab> tap on Scheduled> and toggle to PayTo
  
  CommBank - go to Accounts> then see upcoming bills and payments> select PayTo
  
  NAB- Tap on More> tap Payments> tap PayTo agreements> navigate to the bottom of the agreement details> tap Cancel PayTo agreement
  
  Westpac- go to Service> Services> Account Services> tap on PayTo agreements> scroll to the bottom of the page> press Cancel
  
  Bankwest- go to Payments> Manage> PayTo agreements> select Delete
  
  Unity Bank- head to Pay & Transfer menu> PayTo Agreements> Current PayTo agreements> select Pause or Cancel
