TPG Telecom Limited has received a formal warning from the Australian Communications and Media Authority (ACMA) for failing to promptly notify Telstra about a network outage that affected the Triple Zero emergency call service. The disruption, which occurred on August 15, 2024, left most of TPG’s 4G mobile customers unable to make voice calls, including emergency service calls, for one hour and twenty minutes.

According to the ACMA investigation, although TPG became aware of the outage at 1:22 am, it did not report the issue to Telstra until 9:07 am, contravening emergency call service rules which require immediate notification. ACMA member Samantha Yorke emphasized the importance of timely communication in maintaining the integrity of emergency call services, stating that all telecommunications companies must ensure robust systems are in place to handle such disruptions.

The investigation revealed no direct harm to TPG customers, and the company attributed the delay to human error. TPG has since implemented additional training for its personnel and plans to conduct annual refresher courses on emergency call management processes.

This incident highlights ACMA’s ongoing focus on compliance with emergency call regulations, following significant penalties imposed on Optus and Telstra in 2024 for similar breaches.
