Westpac credit cards have an interest free period on purchases, if your credit card statement's closing balance is paid in full by the due date.

If you make a cash advance, the interest free benefit does not apply and the cash advance accrues interest from the day you make the withdrawal.

If your last card statement closing balance is not paid in full by the due date:

  • Interest will accrue daily on your last card statement opening balance and be charged on your next statement
  • Interest will accrue daily on new purchases from their transaction date, including purchases already made in the current statement cycle.

Here's a guide to help you understand how credit card interest works.
