User reports on Downdetector, an outage analytics site, indicate that Australia's "Big Four" banks are either down or facing problems.

Today, Westpac Bank Corporation, its subsidiary St George's Bank, Commonwealth Bank, National Australia Bank, and ANZ Bank have seen a rise in user reports, as have several other banks.

However, most social media complaints center on Westpac and St George's Bank.

A Westpac customer said they are unable to make card payments, access the banking app, or call the bank.

Other users expressed similar complaints, and some criticized Westpac for providing little communication about the incident.

Westpac says outage likely a technical issue

One user guessed that a malicious actor might be behind the problem, but Westpac told 10 News that the outage seems to be the result of a "technical glitch and not a hack."

According to Westpac, the problems affect its app, online banking features, and PayID.

The bank also apologized for the inconvenience and said its "teams are working to restore these services as quickly as possible."

Update: We’re aware some customers are continuing to experience intermittent issues with the App, Online Banking and PayID / Osko payments. Call centre wait times are longer than usual.

We apologise for the inconvenience and will provide further updates here. https://t.co/kPBm9aqTGB

Last week, 128 Japanese credit unions experienced an outage originating from the Shinkin Joint Center due to "equipment malfunction."

UK banks also had an outage last month caused by a "power event" at a Google Cloud data center.

In both cases, users were unable to perform various transactions.
