Optus outage in South Australia sparks police warning of 000 outage

Another Optus outage has stopped people from calling triple-0.

South Australia Police warned the public on Sunday morning that the outage affected people in the area of Angaston, 60km northeast of Adelaide.

“An equipment fault is impacting mobile voice and data services, which may affect calls to triple-0,” a police spokesperson said.

“Optus technicians are on site working to resolve the issue.

“If you are in an emergency and have no mobile coverage, seek immediate assistance from neighbours, local emergency services, Wi-Fi calling, or community support networks.”

The first alert from the telco said multiple Optus towers in the area of Angaston might be affected, but an updated alert narrowed the issue down.

“There’s an issue with one of our mobile towers in this area,” an updated alert says.

“We’re working hard to fix the problem, until we do, your mobile service may experience some issues. Thanks for being patient with us.”

Two deaths have been directly linked to a 14-hour Optus outage in September 2025, which stymied triple-0 calls in South Australia, WA, the NT and NSW.

Optus commissioned an independent report into the outage, which the company chairman described as “sobering”.

The report was released in December, and recommended sweeping changes to strengthen tests during network outages, making sure staff escalate issues outside their immediate work teams if they have doubts, and even the company board was put on notice to “consider the adequacy of its skill base and depth”.

The independent report of Kerry Schott also recommended speeding up moving call centres onshore.

Optus chief executive Stephen Rue said the report would inform how the company would “reform”, and that many improvements were already underway.

“In line with our commitment to be open about the events of 18 September, we will regularly report our progress to restore confidence in Optus and our network,” Mr Rue said in a statement in December.
