A major Telstra network outage struck in the early hours of Wednesday, July 8, 2026, leaving thousands of customers across Australia unable to make calls or access mobile data — and prompting urgent warnings from police in Western Australia and New South Wales that affected users may not be able to reach Triple Zero in an emergency.
The disruption began at approximately 3am Western Australian time, with reports flooding outage-tracking platforms from every state and territory. By early morning, more than 7,000 individual reports had been lodged, with complaints coming from Sydney, Melbourne, Brisbane, Perth, Canberra and Adelaide, as well as regional centres across Victoria, Queensland and Tasmania.
Telstra confirmed it was investigating the problem, saying it was "looking into an issue affecting some mobile calls and data connections." The company advised customers to try restarting their devices or toggling their WiFi connections while its technical teams worked toward a fix. As of Wednesday morning, no cause had been identified, no estimated restoration time had been given, and no figure had been provided on the total number of affected customers.
Police Warn Telstra Users Over Triple Zero Access
WA Police issued a public statement confirming the outage was affecting some people's ability to call the Triple Zero emergency number. The force urged residents to check on those around them, stating: "If you have a vulnerable family member, friend, neighbour or co-worker, consider offering support during the service disruption."
NSW Police similarly warned that while Triple Zero systems themselves remained operational, customers calling from a Telstra device may be unable to get through. The force recommended switching to a non-Telstra device, a landline, or using Wi-Fi calling as alternatives.
Federal Emergency Management Minister Kristy McBain confirmed the outage was affecting "a large number" of calls and connections nationwide. She noted that under existing rules, Australian phones are required to fall back to other networks for Triple Zero access, and said the government understood Telstra was working to resolve the issue.
Transport Networks and EV Chargers Also Hit
The outage extended well beyond phone calls and mobile browsing. Victoria's entire regional train network was disrupted, with V/Line passengers urged to seek alternative routes as services were delayed or cancelled. Reports indicated dozens of trains were stopped at regional and suburban Melbourne stations. V/Line services approximately 70,000 Victorians each day, meaning the impact on commuters was substantial. Minister McBain confirmed the transport disruption as part of the broader outage effect.
One traveller described beginning a journey from regional New South Wales to Melbourne in the early hours of the morning, only to find their connecting V/Line train service first delayed and then cancelled due to the outage, forcing them onto a bus replacement service.
Electric vehicle charging was also affected. EV charging platform Chargefox advised that the Telstra outage was disrupting the availability of some chargers on its network, warning that users whose mobile devices were on the Telstra network may not be able to access chargers at all due to the loss of mobile connectivity. The company directed customers to check its app for real-time charger status.
Likely a Software Issue, Technologists Say
A technology journalist speaking on radio described the fault as "more likely to be a software problem at Telstra," pointing to the nationwide spread of the disruption as evidence against a hardware failure. "If this was hardware it wouldn't be affecting everyone across the country," he said, noting that all capital cities and many regional areas were impacted.
He recommended a simple workaround for affected customers: switching flight mode on for approximately three seconds, then turning it off again. This forces the handset to re-establish a connection with the network and may restore service in some cases. Some customers reported this method worked temporarily, while others found it had no effect. Reports from customers also noted unusual behaviour, including cases where one device on the Telstra network had full service while another in the same household did not, and instances where an older phone model accepted the SIM card and connected while a newer handset failed.
Competitor network Optus confirmed its own systems were operating normally throughout the morning.
A Pattern of Major Outages for Telstra
The Wednesday morning outage is not the first time Telstra has faced widespread network failure in recent years. Previous major outages have left large numbers of customers without mobile service and raised serious questions about network reliability. A highly publicised system failure in March 2024 disrupted emergency service lines due to a technical fault that prevented information from being passed through to emergency services. That incident was resolved within approximately 90 minutes, but its consequences were severe — a Victorian man died after his family's emergency calls were delayed during his cardiac arrest.
In June 2026, Telstra also reduced its reported mobile network coverage area by almost a third after new federal rules came into force requiring telecommunications companies to measure and report signal strength using standardised methods, making it easier for consumers to compare coverage across networks.
As of Wednesday morning, Telstra had not provided a timeline for restoring full service, and customers across the country were being urged to keep non-Telstra devices accessible in the event of an emergency.
