Telecommunications Outages Highlight Urgent Need for Emergency Connectivity Reforms Across Australia

Recent telecommunications outages in Victoria, particularly during bushfires and those linked to a specific iPhone software update, have brought critical concerns regarding emergency service connectivity to the forefront. These incidents closely follow a major Optus outage last year which severely impacted Triple Zero (000) calls and is currently the subject of a federal Senate inquiry. In response, industry trials for disaster roaming are underway, and government initiatives are aiming to significantly improve network resilience nationwide.

Recent Connectivity Failures in Victoria

During recent bushfires in Victoria, both residents and emergency services faced significant telecommunications disruptions.

Bushfire-Related Disruptions

A CFA group officer reported a complete loss of phone service in the Natimuk area, severely affecting coordination efforts. Nearby residents were also left unable to contact family during evacuations, amplifying anxiety and risk. Telstra confirmed that a power outage at its Mount Arapiles mobile site, which serves Natimuk, was responsible, caused by a mechanical fault in a back-up generator under extreme weather. Services were eventually restored the following day after safe access to the site was secured.

iPhone Software Update Glitch

Separately, some Telstra customers in regional Victoria, including those in bushfire-affected zones, reported losing mobile phone service and the ability to contact Triple Zero (000) following an Apple iPhone software update. This specific issue impacted iPhone 8, 8 Plus, and X devices. Reports included a Harcourt resident losing all coverage and a Telstra Priority Assist customer in the Strathbogie Ranges unable to send texts or connect to 000. Telstra and Apple later provided instructions for customers to resolve the problem via an operating system update.

Broader Bushfire Impact on Optus

Optus reported that a total of 112 of its mobile sites were affected by the extreme heat and bushfires in Victoria. All these sites have since been fully restored, with Optus noting that its sites are designed to include a minimum of four hours of battery back-up.

Scrutiny on Triple Zero Reliability

The broader reliability of connecting to Triple Zero (000) services has been under intense scrutiny, particularly since the major Optus outage last year.

The Major Optus Outage of 2023

A significant Optus outage on September 18 last year, lasting 14 hours, was tragically linked to two fatalities. During this period, 605 Optus customers attempted to reach Triple Zero, with the majority encountering silence, failing to connect.

Senate Inquiry and Dr. Schott's Findings

A Senate committee has convened hearings to review the Optus outage, questioning figures such as Optus CEO Stephen Rue and Dr. Kerry Schott, who led an independent review. Greens Senator Sarah Hanson-Young raised serious concerns regarding Optus's risk management system and its public safety priorities. Optus CEO Stephen Rue stated he could not guarantee the prevention of future network outages.

Dr. Schott's report, titled 'The Triple Zero Outage At Optus: 18 September 2025' (likely referring to the 2023 outage), documented multiple errors in Optus's network upgrade implementation and risk management procedures. Key findings indicated significant communication failures, with call center staff initially unaware of the major network problem and treating calls as routine technical faults. Escalation of the issue only occurred after awareness of two fatalities. The Senate inquiry's report into the Optus Triple Zero outage is expected in March.

Industry and Government Drive for Resilience

Federal MP Helen Haines has been a vocal advocate for measures to secure telecommunications during natural disasters.

Disaster Roaming Trials and Challenges

Haines's advocacy includes implementing temporary disaster roaming and ensuring reliable back-up power for mobile phone base towers. Temporary disaster roaming, which allows cross-network usage when one network fails, is already available for Triple Zero calls but experienced failures during previous Optus outages.

Telstra, TPG, and Optus commenced trialing disaster roaming in November, a federal government initiative that has been collaborated on since 2023. Telstra has, however, noted potential challenges, such as preventing network overload on the surviving networks. The federal government has also invested in programs specifically designed to enhance telco network resilience, funding back-up batteries and generators for critical infrastructure.

Expanding Coverage and Infrastructure Investment

A Universal Outdoor Mobile Obligation (UOMO) is planned for launch in December 2027, with the ambitious goal of ensuring phone call and text coverage across Australia, partially utilizing satellite technology. The National Farmers' Federation president, Hamish McIntyre, expressed strong support for both UOMO and temporary disaster roaming, highlighting their critical importance for farmers and local emergency responders during crises.

Strengthening Oversight and Accountability

Concerns persist regarding the effectiveness of current regulatory frameworks in the telecommunications sector.

Calls for Enhanced Regulation

The Australian Communications Consumer Action Network (ACCAN) Head, Carol Bennett, expressed concerns about the effectiveness of self-regulation in the telco sector. She strongly advocated for increased government and regulatory action to prevent further Triple Zero connection failures.

The Role of the Triple Zero Custodian

The office of the Triple Zero Custodian, whose legislative powers regarding outages impacting emergency calls became effective four months prior to the Optus outage, actively monitors such matters. The Custodian escalates issues to the Australian Communication and Media Authority (ACMA) and industry as needed. Device compliance and Triple Zero disruption notifications were identified as key priorities by the Custodian. The federal communications minister's office affirmed ongoing work by the Custodian and ACMA to strengthen the Triple Zero system and hold telcos accountable.

Optus's Reforms and Future Outlook

In response to the critical findings and public outcry, Optus CEO Stephen Rue stated that the company is actively implementing improvements based on Dr. Schott's review and its 21 accepted recommendations.

Implementing Review Recommendations

Key changes introduced by Optus include:

• Introduction of new onshore call center roles to improve customer service.
• Strengthened escalation processes across call centers and the business for faster problem resolution.
• Improved real-time visibility and monitoring of Triple Zero performance.
• A new automated welfare check process for outages impacting Triple Zero.
• Substantial changes to executive leadership in critical areas such as network security, technology, legal, compliance, and risk.

Optus management now reports to a strengthened board, which operates separately from Singtel, with further cultural strengthening planned as part of a long-term transformation program.
