From 1 December 2020, you'll no longer be able to use your credit card to make transactions related to gambling or lotteries. We will be doing this by blocking transactions from merchants that are classified under the gambling merchant category code. More information.
The interest free period starts on the first day of the “statement period” and ends on the payment due date. The “statement period” and “payment due date” are always shown on your credit card statement.
All purchases made in the statement period (usually the first day of the month through to the end of the month ie 1 Dec – 31 Dec), must be paid in full by the statement of account due date (usually the 24th of the following month) to avoid interest charges.
