ACT supermarkets, Canberra Airport, banks and the ABC are being affected by a global computer outage related to Microsoft Windows.
Social media posts are saying Big W, K-Mart and Coles self-serve checkouts are impacted, with some taking cash only.
At Canberra Airport, a plane is reportedly stuck on the tarmac with passenger booking screens down.
A spokesperson said the IT issue is impacting check-in for some airlines at Canberra Airport.
” If people are travelling they should stay up to date with messages from their airline,” the spokepserson said.
None of the screens at Sydney Airport are working, according to a post on X, and Melbourne Airport is also experiencing check-in delays.
Both Virgin and Qantas are affected.
Computers are also down at ABC News, and presenters are limited to talking straight to camera, without captions, reports and graphics.
Canberra reporters are unable to file their reports.
Banks affected include National Australia Bank, Bendigo Bank and the Commonwealth.
The National Cyber Security Coordinator says the outage relates to a technical issue with a third-party software platform employed by affected companies and is not a cyberattack.
The Federal Government said it was working closely with the National Cyber Security Coordinator on this unfolding outage.
Telstra says global issues affecting CrowdStrike and Microsoft are disrupting some of its systems.
“The issue is causing some holdups for some of our customers and we thank them for their patience,” it says.
“There is no impact to our fixed or mobile network, which continue to operate.
“Calls to our Triple Zero contact centres are not affected, but we understand some state emergency services are also impacted and we are working with them to implement backup processes.”
