Telstra CEO Apologises as Legacy Timekeeping Glitch Behind Outage; Elderly Person's Death Under Investigation in South Australia

A software glitch knocked out Telstra's network across Australia, and South Australian police are investigating a death that occurred during the outage.

A major Telstra network outage, caused by a software defect linked to legacy timekeeping technology dating to 2006, left large numbers of Australians without mobile and internet service, disrupting triple-zero emergency calls, regional train services, Eftpos payments, traffic lights, and electric vehicle charging infrastructure. Telstra confirmed the outage was not the result of a cyber-attack but warned of scammers impersonating the company in its aftermath. CEO Vicki Brady made her first public appearance since returning from overseas, offering a deep apology and acknowledging that the risk of a timekeeping failure had been known. Federal Aged Care and Sports Minister Anika Wells maintained pressure on the company, saying it was 'time for Telstra to face the music.' South Australian police confirmed they are investigating the death of an elderly person, following claims by Liberal senator Kerrynne Liddle that the death was linked to the outage; Senator Sarah Henderson's related triple-zero calls during the disruption have been defended by Taylor. Analysts and commentators noted the outage has significantly damaged Telstra's long-standing reputation as Australia's most reliable and widest-coverage mobile network, raising broader questions about the resilience of critical single-system infrastructure.

Why it matters

Telecommunications outages can have life-threatening consequences when people are unable to contact emergency services, and this case illustrates that risk directly. As Australia's largest telco, a Telstra network failure has broad national impact across consumers, businesses, and public safety infrastructure.

What's next

South Australian police are expected to continue their investigation into the death, while Telstra faces ongoing political and public scrutiny over the cause and handling of the outage.

Key facts

• A software glitch was identified as the cause of a major Telstra network outage affecting customers across Australia
• South Australian police opened an investigation into a death that occurred during the Telstra outage

Bias & framing notes

All three sources are Guardian live blog formats, which provide running updates rather than a single consolidated report, limiting the detail available here. The framing across the three blogs shifts from technical cause ('software glitch') to political accountability ('face the music') to public safety consequences (the SA death investigation), reflecting how the story's emphasis evolved over time rather than any ideological bias. No independent non-Guardian sources were provided, which limits corroboration.
