Millions of Calls Missed the Mark: Optus Outage Sparks Scrutiny of Triple-0 System
The integrity and reliability of Australia’s emergency call system, triple-0, are under intense scrutiny following a significant outage in September 2025 attributed to Optus. An inquiry by the Environment and Communications References Committee has revealed a startling statistic: while over 14 million calls were made to triple-0 in 2025, a substantial number, estimated to be around three million, never reached emergency services.
Clare Chapple, representing Triple-0 Custodian, informed the inquiry that out of 14.6 million calls placed to the emergency number in 2025, only 11.7 million were successfully answered. Of those answered, a further significant portion, approximately nine million, were ultimately transferred to the relevant emergency services. This leaves a concerning gap of millions of calls that were either disconnected, failed to connect, or were deemed non-emergency in nature, such as accidental “pocket dials.”
Greens Senator Sarah Hanson-Young highlighted the lack of precise data regarding the exact number of failed calls. “So, really, what we don’t know is the difference,” she stated, prompting Ms Chapple to admit that while the general reasons for call drop-offs were understood, a detailed breakdown was not immediately available. The inquiry was informed that Telstra, the contracted provider responsible for handling triple-0 calls across Australia, is legally obligated to maintain records of calls that fail to connect.
However, Senator Hanson-Young expressed frustration over the limited data presented to the committee, citing a survey by the Australian Communications Consumer Action Network (ACCAN) that indicated one in ten calls failed to connect. “I get that the big telecommunications companies won’t be happy to see these figures being bandied around. I get that,” she remarked, questioning the committee’s ability to conduct a thorough investigation in the absence of comprehensive data.
The inquiry also delved into the effectiveness of current regulatory oversight. A review conducted by the Department was questioned, with Liberal Senator Sarah Henderson suggesting it was an internal “investigation of itself.” Ms Chapple defended the review, clarifying that its focus was on the “settings” of the system rather than its direct performance. She explained that any identified issues with the settings that warrant change would be recommended for implementation.
Looking ahead, Ms Chapple indicated that the review would also examine emerging technologies and their potential impact on the future of the triple-0 service. “Have we got a system that is fit for purpose now, but also in that future where there are new technologies and the current environment is written to preface voice so, you know, that is something that we need to look at,” she explained. The aim is to ensure consumers can access triple-0 using the most current and convenient technologies available.
This forward-looking approach involves extensive collaboration. Ms Chapple stated that work is underway to establish a roadmap for the future of triple-0, beginning with an assessment of regulatory and legislative frameworks. Furthermore, significant effort is being dedicated to working with emergency service partners and international counterparts to gain insights into their strategies.
Optus, in its previous appearances before the committee, had indicated progress in rectifying its systems and improving its reporting culture. Ms Chapple affirmed that the Department’s role includes monitoring and enhancing the entire triple-0 ecosystem, which encompasses all telecommunications providers, including Optus.
Key Challenges Facing the Triple-0 System:
- Call Failure Rates: A significant percentage of calls to triple-0 do not reach emergency services, with the exact number requiring further investigation.
- Data Gaps: Insufficient detailed data on call failures hinders a comprehensive understanding of the problem and its causes.
- Technological Evolution: The need to adapt the triple-0 system to new communication technologies and ensure accessibility for all users.
- Regulatory Oversight: Ensuring that regulatory bodies are adequately equipped and empowered to oversee the performance and reliability of emergency call services.
- Provider Accountability: Holding telecommunications companies accountable for maintaining robust and reliable emergency call infrastructure.
Ms Chapple reiterated the Department’s commitment to holding all telcos, including Optus, accountable for implementing necessary improvements and making “step changes” to ensure the continued effectiveness of the triple-0 service. The ongoing review and collaboration aim to fortify the system against future disruptions and ensure it remains a reliable lifeline for Australians in need.
