National Australia Bank customers have been hit by a widespread service outage, with internet banking, the NAB mobile app and several other digital platforms affected. The disruption has also made it harder for some customers to reach the bank by phone. Here is what is known so far about the NAB outage, the services affected and when banking access could return.
National Australia Bank is dealing with a significant digital outage that has disrupted access to some of its most widely used banking services.
Customers reported problems logging into NAB Internet Banking and the bank’s mobile app on Wednesday, September 23, while disruptions were also reported across a number of business, trading and wealth management platforms. NAB acknowledged problems across multiple digital channels and said its teams were working on a fix.
The outage has gone beyond customers simply being unable to check their account balance. Reports indicate that some people have been unable to make or receive digital payments, while others have faced difficulties contacting NAB by phone.
For anyone searching “is NAB down?” or wondering why their NAB app is not working, the short answer is yes, multiple NAB services are experiencing an unplanned outage. What remains unclear is exactly what caused it and how long a full recovery will take.
What happened to NAB?
NAB confirmed that multiple digital banking channels were experiencing problems.
Internet banking and the NAB mobile app were among the most visible services affected, leaving customers unable to access accounts through the bank’s usual online channels. Reports also identified disruption to NAB Connect, NAB Trade, NAB Broker and JBWere.
Customers attempting to use the mobile app were shown an outage message saying the app was not working and would be restored as soon as possible.
The disruption was not limited to personal banking. NAB Connect, which is used by business customers, was also among the affected services, alongside trading and brokerage platforms.
That wider spread is important because it means the problem is affecting several parts of NAB’s digital banking infrastructure rather than a single feature inside the mobile app.
Is the NAB app down?
The NAB mobile app is one of the services confirmed to be experiencing problems.
Customers have reported being unable to log in, while NAB’s own outage messaging acknowledged that the app was not working normally. Internet banking has also been affected, meaning switching from the app to a browser may not solve the problem for every customer.
For some users, the disruption has also affected the ability to carry out payments rather than simply view their accounts. SmartCompany reported that customers were being prevented from sending or receiving digital payments during the outage.
Which NAB services are affected?
The disruption has been reported across:
- NAB Internet Banking
- NAB Mobile App
- NAB Connect
- NAB Trade
- NAB Broker
- JBWere
- Some phone-based customer service access
NAB has acknowledged that customers were also having difficulty contacting the bank over the phone.
Nine reported the outage as a broader network disruption affecting internet banking, the mobile app and customer-service access.
Why is NAB down?
At this stage, there is no confirmed public explanation for the cause of the outage.
NAB had not identified a suspected cause in the available reports, and there was no announced restoration time.
One detail does rule out an obvious explanation: this was not scheduled maintenance. NAB said no planned maintenance had been scheduled, making the disruption an unexpected outage.
Until NAB provides a technical explanation, it would be speculative to attribute the outage to a cyberattack, software problem, infrastructure failure or any other specific cause.
How are customers being affected?
The most immediate impact is loss of access to digital banking, but customer reports suggest the outage is also creating problems in everyday transactions.
Some customers said they could not pay for goods and services. One person reported being unable to make a payment at a chemist, while another said a long trip to purchase car parts ended without the purchase being completed because of the banking disruption.
Those accounts underline why an online banking outage can quickly become more than an inconvenience. For customers relying on their phone for banking and payments, losing access can interfere with purchases and other routine transactions.
When will NAB banking be back online?
There is no confirmed restoration time yet.
NAB said its team was working to restore affected services “as soon as possible” and apologised for the inconvenience.
The bank had not provided an estimated time for services to return in the reports available at the time of writing.
That means customers seeing errors in NAB Internet Banking or the mobile app may need to wait for further updates from the bank rather than repeatedly changing devices or reinstalling the app.
Has NAB had another outage recently?
This is not the first disruption to NAB’s digital banking services in recent weeks.
SmartCompany reported that an earlier outage in August had temporarily affected NAB’s mobile and desktop banking systems.
The available information does not establish that the two incidents are connected, so it would be premature to treat the September outage as a continuation of the earlier problem.
What we know so far
The picture at this stage is relatively clear: NAB is experiencing an unplanned outage affecting internet banking, its mobile app and several other digital platforms. Some customers have also encountered problems with payments and phone support.
What is still missing is the technical cause and a firm timeline for recovery.
Until NAB provides those details, claims about what triggered the outage would be speculation. For customers, the most relevant update will be confirmation that normal access to banking, payments and affected business platforms has been restored.
