NAB restores most services after bank outage; some business logins still disrupted
Published · Updated
What happened
NAB's mobile banking, internet banking and phone banking services were disrupted on September 23, and by September 24 the bank said most services were back online while some NAB Connect business users still could not log in.
Why it matters
A service outage at one of Australia's major banks can interrupt retail banking, business payments and customer access to funds even after partial restoration. It also puts attention on incident disclosure, backup arrangements and whether other institutions face similar operational weaknesses.
National Australia Bank suffered a digital outage on September 23 that affected its mobile app, internet banking and phone services. ABC reported on September 24 that most services had been restored, but some business customers were still facing login issues through NAB Connect. The event keeps operational resilience at a major bank in view for Treasury, APRA and ASIC because continuity, customer trust and payment access remain live issues until full restoration and any cause analysis are confirmed.
