If this is a new credit card, then yes, you'll need to arrange a new direct debit for your new card by completing a direct debit application, which you can download here or pick up at any Westpac branch.

If you are transferring into a Westpac Airpoints credit cards from another Westpac credit card, we will automatically transfer any existing direct debit arrangement to your new Westpac Airpoints credit cards.

In both instances however, please remember to change over any subscription services you may have (such as Netflix) and regular payments (e.g. your power company, telecommunications or public transport provider) - to your new card.
