News Summary:

Optus is contemplating cybersecurity policies, including a potential ban on smart glasses in its stores and offices, as revealed on September 17, 2026, by Optus EGM security and risk Corien Vermaak at a Zscaler customer event, noting it has become "a definite conversation point." This consideration follows a series of network disruptions for the telecom operator. On September 16, 2026, details emerged regarding a 76-minute technical glitch on September 11 that impacted network users across Victoria, Tasmania, and South Australia, causing "intermittent call dropouts." Previously, on September 15, 2026, police conducted dozens of welfare checks after approximately 40 callers to Triple Zero were unable to connect during a 90-minute Optus mobile network outage over the weekend, which interrupted mobile voice services across a wide swath of the country. The Australian government responded to these issues, flagging further work to strengthen telecommunications network resilience on September 14, 2026, after the September 11 outage affected voice services, including some Triple Zero calls, across parts of Victoria, South Australia, Tasmania, and the Northern Territory. On September 13, 2026, the government had already pledged to bolster resilience in the country’s telecommunications networks following the outage at Optus, the nation's second-largest carrier, which disrupted emergency services calls and impacted users in three states.
