Optus Faces $250 Million Penalty for Catastrophic Triple Zero Outage That Left Hundreds Stranded in Life-Threatening Emergencies
- Optus sued in Federal Court over September 2025 outage that prevented hundreds from reaching Triple Zero, linked to two deaths
- ACMA alleges telco breached two legal obligations over 1,000 times, with maximum penalty of $250,000 per contravention
- Expert review finds widespread failures, including 10 crucial mistakes, contributed to outage and delayed resolution
- ACMA Chair Nerida O’Loughlin warns telcos that access to emergency call service is “not optional” and a “fundamental legal obligation”
The nation’s second-largest telco, Optus, is facing a potential $250 million penalty for a catastrophic network outage in September 2025 that left hundreds of people unable to reach Triple Zero in life-threatening emergencies.
The Australian Communications and Media Authority (ACMA) has launched a Federal Court action against Optus, alleging the telco breached two legal obligations over 1,000 times during the 14-hour outage.
The outage, which was linked to two deaths, was caused by a routine network upgrade that was plagued by multiple failures by Optus and its contractor Nokia.
A review by experienced business and public service executive Kerry Schott found that as many as 10 crucial mistakes were made, including the failure of the Optus call centre to escalate warnings from five callers who reported that Triple Zero calls were failing.
The review also found that Optus needed to overhaul its network operations, which “clearly failed”, and improve risk management and internal audit functions.
One woman’s terrifying experience during the outage was revealed in the review, where she was unable to call Triple Zero after robbers broke into her home while she was in the bedroom.
The ACMA has warned that the public must be able to access Triple Zero in an emergency, and that telcos have a “fundamental legal obligation” to ensure this happens.
This is not the first time Optus has faced action from the ACMA. In 2023, the telco paid over $12 million in infringement notice penalties for a previous outage that affected emergency calls.
The recurrence of a major network outage affecting emergency calls so soon after the 2023 outage has sparked concerns about the telco’s ability to manage its network.
Telecommunications industry expert and RMIT University associate professor Mark Gregory welcomed the ACMA’s decision to take Optus to court, saying that the penalties reflect the seriousness of the situation.
“It’s about time the penalties reflected the seriousness of what’s happened,” he said. “The telecommunications industry has been put on notice.”
Analysis: What This Means for Australia
The Optus outage has significant implications for Australia’s national security and public safety. The inability of hundreds of people to reach Triple Zero in emergency situations raises serious concerns about the reliability of the country’s telecommunications network.
The ACMA’s decision to take Optus to court sends a strong message to telcos that they will be held accountable for their actions.
The outage also highlights the need for tougher regulatory obligations and greater accountability in the telecommunications industry.
The federal government’s introduction of new laws in 2023, which established a Triple Zero Custodian and gave the ACMA greater powers, is a step in the right direction.
However, more needs to be done to ensure that telcos prioritize people’s safety and take their responsibilities seriously.
As the ACMA Chair Nerida O’Loughlin warned, access to the emergency call service is “not optional” and a “fundamental legal obligation”. It is imperative that telcos take this responsibility seriously and invest in network resilience, transparency, and accountability to prevent such outages from happening again.
Security analysts say that the Optus outage is a wake-up call for the telecommunications industry, highlighting the need for greater investment in network infrastructure and cybersecurity.
Law enforcement insiders warn that the inability of emergency services to respond quickly and effectively in emergency situations can have devastating consequences.
