National Australia Bank customers reported service disruptions from shortly after midday on September 23, when the mobile app, internet banking and phone lines went down across multiple platforms. As of the latest update from NAB, most services have been restored — but some business customers are still reporting login problems.
NAB confirmed a digital outage that affected multiple services simultaneously: internet banking, the NAB mobile app, NAB Connect, NAB Trade, NAB Broker, JBWere and customer-service phone lines. The bank said most services had been restored, but some business customers continued to experience login issues after the main recovery. NAB did not publicly disclose a cause. The bank confirmed that no scheduled maintenance was planned during the affected period.
If you are a NAB personal banking customer, your app and online banking access should be working again. If you are a business customer still unable to log in to NAB Connect or NAB Trade, no specific resolution time has been given. Check NAB’s official app and status page for live updates — third-party outage trackers can lag behind the actual situation. Do not rely on social media reports about the cause: NAB has not disclosed what caused the outage, and any specific cause being circulated — including suggestions of a cyberattack — is speculation, not confirmed fact.
For customers who missed a payment or experienced a transaction error during the outage, contacting the bank directly with a time-stamped record of the failed transaction is the recommended step.
The outage affected multiple major banking services simultaneously. The absence of any explanation from NAB means the nature of the problem remains unknown.
Closure: NAB has restored most services. Business customers still experiencing issues should monitor NAB’s official updates directly. The bank has not indicated when a full explanation will be provided.
