Thousands of Telstra customers have been unable to make calls or access their data on their mobiles on the country’s largest network.
The telecommunications provider that powers some 25 million mobile services nationwide confirmed the outage on Wednesday.
“We’re looking into an issue affecting some mobile calls and data connections,” Telstra said on X.
“We’re on it and will share an update as soon as it’s fixed. Thanks for bearing with us.”
⚠️ We're looking into an issue affecting some mobile calls and data connections. If you're having trouble connecting at first, try again as it may work on a retry. We're on it and will share an update as soon as it's fixed. Thanks for bearing with us. — Telstra (@Telstra) July 7, 2026
More than 7500 customers reported the network disturbance on online monitoring platform Downdetector.
The latest outage comes after other telecommunications giants Vodafone and Optus experienced recent gaffes that proved fatal.
In June, Vodafone customers were left with intermittent reception and data issues across Australia.
The telco said customers who could not access the network were able to use emergency triple zero by connecting to other available mobile networks.
Two deaths have been linked to an outage at Optus in September 2025, which lasted almost 14 hours and affected hundreds of calls in four states and territories.
New rules were handed down by the Australian Communications and Media Authority in March forcing telcos to publish when the outage started and when it was restored in detail as well as the cause.
