- Summary: Card payments were declined across customers of multiple Australian banks on the Saturday afternoon, with recovery reported around 16:00 local time. Mastercard's own statement names a scheduled system update and states the situation is resolved. The Commonwealth Bank published a working fallback during the incident, telling customers to insert the card and select savings to pay over EFTPOS. No incident report with a start time, an end time or affected regions was published at the time of writing, so the impact window here comes from the reporting rather than from a status page.
- Why it matters: A scheduled change inside a card network removed authorisation for every bank downstream of it, and the recovery path customers were given was a different rail rather than a retry.
- Follow-up: Check for a Mastercard incident report giving a start time, an end time and affected regions.
