Yesterday, numerous businesses and services around NSW and Queensland reported outages for their EFTPOS and ATM machines. What was initially thought to be an outage affecting one or two major banks turned out to be a system-wide issue. The problems also extended to other states and territories.

In short, Australia’s entire cashless network went down for several hours — and it looks like Telstra is to blame.

The outage occurred between 2:30pm to 5:30pm on 11 July, a Telstra spokesperson confirmed to Gizmodo Australia, and affected Telstra’s IP network services including EFTPOS, ATM services and some payment platforms. While the issue has since been resolved, Telstra has yet to reveal the cause of the issues.

Early investigations suggest “an unusually large volume of traffic across network links in NSW” is to blame.

Despite reports indicating it affected NSW and parts of Queensland, Down Detector, a real-time peer-to-peer services status site, showed outages across the entire country.

For those three hours, banks weren’t the only ones affected. Customers and businesses complained that cashless payments were unavailable and with most ATMs inaccessible, many were left stranded without access to their money.

While the three-hour debacle might seem small in the grand scheme of things, it brings up an important question: In an increasingly cashless world, what happens when the systems we rely so heavily on fail us?

With that in mind, let’s take a look at all the services and companies affected by the outage to illustrate just how far-reaching Telstra’s outage was.

The major banks

Initial reports seemed to suggest only one or two of the major banks were being affected by the outage but it soon became apparent the outage affected most banks across Australia. Commonwealth Bank confirmed while EFTPOS and ATM services were down, internet banking remained unaffected.

Later that evening, Westpac confirmed services were up and running again.

Australia Post

Even Australia’s national postal service was affected by the outage. In a since-deleted tweet, AusPost reported they were “experiencing software issues in retail and urgently seeking a fix”, according the ABC. “EFT payments over $100 & Agency payments over $200, [email protected] withdrawals, deposits and balance enquiries are affected. Commbank withdrawals under $100 and deposits of any kind are unaffected.”


One of Australia’s largest supermarkets, Woolworths was not spared from the Telstra outage’s path of destrution. The Woolworths at Town Hall in Sydney’s CBD had to make use of a cardboard sign declaring they could only accept cash.

At 6.03pm yesterday, a Woolworths spokesperson confirmed with Lifehacker that connection was back up and running. “Telstra has advised us the network connection is back up and running. We expect our systems to come back online and resume normal service through check-outs over the next hour. We apologise to customers for the inconvenience and delays in shopping this afternoon,” the spokesperson said to us in an email.

“Stores are continuing to trade and we thank customers for their patience.”

Government departments

The Department of Veteran’s Affairs also issued a confirmation of their issues with the outage.

Petrol stations

Caltex faced problems when customers were left without a cashless method of payment.

Fast food outlets

McDonald’s’ customers reported having issues with payment during The Great Outage. The fast-food outlet didn’t confirm the news but we’ve reached out for comment.

State ambulance services

Ambulance services were reported to have been affected as well, according to the ABC, but they stressed that emergency services continued on as usual.

Even local libraries

Even the local libraries weren’t safe with Sydney’s Dundas and Constitution Libraries both facing technical difficulties during the outage.

Telstra has yet to offer an official explanation behind the reason for the outage. We’ve reached out for comment and will update as soon comment is received. In the meantime, Lifehacker recommends keeping some hard cash on you at all times in case of future network failures.


  • So they can’t even look after this system and they want to control the ndn. Just imagine what a bigger mess it would be if they got a hold of it too. Glad they got turned down again.

  • I’d read about this on Gizmodo yesterday, but forgot when I popped out at around 4.30pm – Woolies had closed off the self-checkouts and the lines were huge; and at Bunnings they reverted to using the old-style credit card imprint machine (complete with carbon paper!) to get some people through the checkouts. Luckily I had cash on me so I got through reasonably quickly.

  • I was buying groceries at Woolies about 4:30 and I used my savings card, but had to sign the receipt. So I assume the lines were still down then. I know these outages are rare but when they happen they’re catastrophic for people who try to live “Cashless”.

    Be interesting to know whether there are any penalties for the people/company at fault in situations like this.

    • Some lowly employee will be fired as a scapegoat.

      While the CEO and those higher up will still get their million dollars bonuses at the end of the year.
