Some NAB EFTPOS transactions that were accepted through merchant facilities between 12:00pm and 4:00pm on 30 May 2024 were duplicated.

These duplicated transactions have been fixed, and merchants have not received the value of these transactions. Some merchants may have been charged service fees on these transactions and they will show in the transaction count on the merchant statement.

These additional service fee charges will be refunded, and a letter confirming the refund amount will be sent in the coming days.
