Fatal emergency call outage in Australia puts Optus and Singtel leadership under scrutiny
Singtel’s Australian subsidiary, Optus, is facing a fresh crisis after a network outage blocked emergency calls, resulting in multiple deaths and triggering a government investigation.
A Crisis Resurfaces
On September 18, a routine network upgrade at Optus led to a technical failure that disrupted emergency calls across South Australia, the Northern Territory, and Western Australia. The disruption went undetected for 13 hours and left at least three people dead, reigniting concerns over Optus’ reliability.
Political and Public Backlash
Australian Communications Minister Anika Wells condemned the failure, expressing “unbelievable disappointment” to Optus CEO Stephen Rue. Prime Minister Anthony Albanese added weight to the criticism, calling Optus’ conduct “completely unacceptable” and hinting at Rue’s potential resignation. Both officials signaled readiness to introduce regulatory reforms to prevent future tragedies.
Financial And Leadership Strain
The fallout swiftly hit Singtel, which owns Optus and derives about half its revenue from the Australian unit. On September 22, Singtel’s share price fell 1.8% to SGD 4.33, with 15.9 million shares traded. This comes less than two years after a nationwide Optus outage in November 2023 that cost CEO Kelly Bayer Rosmarin her job. Rue, her successor, is now facing similar pressure.
Regulatory Scrutiny Intensifies
The Australian Communications and Media Authority (ACMA) has launched an investigation into whether Optus breached emergency call obligations. Telcos are required not only to maintain uninterrupted access to emergency services but also to check on callers who attempted failed emergency calls. Optus was previously fined AUD 12 million (SGD 10.2 million) for failing to meet these requirements in 2023.
Company Response And Next Steps
In response, Rue announced that an independent expert will review the outage and make public recommendations. Optus has halted all network system changes, introduced 24/7 monitoring of emergency call volumes and failure rates, and implemented a compulsory escalation process for customer reports of outages. Rue admitted the company received at least five early warnings from customers but failed to act on them internally.
Broader Implications
The latest failure highlights systemic weaknesses at Optus and raises questions about Singtel’s oversight. For Singapore, where Temasek Holdings is the majority owner of Singtel, the crisis underscores reputational risks tied to its largest overseas investment. For Indonesians relying on Optus’ cross-border connectivity, the incident demonstrates how network instability abroad can carry real and fatal consequences.
The Optus outage has deepened scrutiny on Singtel’s leadership, financial stability, and governance, amplifying calls for reform in Australia’s telecom sector. As regulators push for stronger protections, the crisis is a sobering reminder for Singaporeans and Indonesians alike of the life-and-death responsibility telecommunications firms hold in safeguarding public trust.
