Telstra customers across the country are reporting that the provider’s mobile network has crashed, potentially leaving millions of Australians unable to make phone calls or access the internet.

Outage detection site Downdetector.com shows a large spike in reports beginning about 5am AEST.

A graph shows no reports until about 4:30am, and then a large red spike just before 6am.

Users of other mobile providers that operate on Telstra’s network, including Boost, Aldi, Tangerine, Belong and Everyday Mobile, are also reporting outages.

However, the outage does not appear to be affecting all the telco’s customers, with some reporting on social media that they are still able to make calls, access the internet, or both.

Calls to Triple Zero (000) should be unaffected by the outage, with calls rerouted to use other providers’ mobile networks.

Network failures will continue if regulator doesn’t act, advocate says

Carol Bennett believes self-regulation within the telco sector is not working, and says there’s a risk of more connection failures unless the government and its telecommunications regulator act now.

A Telstra spokesperson told the ABC the company is looking into “an issue affecting some mobile calls and data connections”.

“If you’re having trouble connecting, try again as it may work on a retry,” the spokesperson said.

“We’re on it and will share an update as soon as it’s fixed. Thanks for sticking with us.”

NSW Blues legend and ABC broadcaster Luke Lewis is one of those whose morning has been affected by the outage, telling ABC News Breakfast he was unable to pay for his taxi on the way to Sydney airport.

“It’s been a little bit crazy. Even on the way here, the taxis today, their internet’s not working,” he told Catherine Murphy.

“I had to give [the taxi driver] my number, I said … just send it to me, and I’ll fix it up later.”

Josh Meadows was set to commute from Castlemaine, in central Victoria, to Melbourne this morning when, after his train arrived at the station, he heard an announcement that it couldn’t proceed due to a “Telstra radio network fault”.

“I sat on the train for half an hour [it was nice and warm inside the train!] then … decided I’ll have to work from home,” he said.

A federal government spokesperson told the ABC that Telstra, like all telcos, “must notify customers and emergency services of any major outage”.

Telstra operates Australia’s largest mobile network, providing about 24.9 million retail mobile services as of June last year.

The company was fined more than $3 million in 2024 for a network outage that prevented customers from calling Triple Zero.
