Four Australians died following a catastrophic Optus network failure last month that knocked out emergency services across the country, with new revelations showing the federal government failed to detect warning emails sent to an unmonitored inbox two weeks before officials were alerted to the crisis.
The telecommunications giant sent notifications about the triple-zero outage to an outdated Communications Department email address on Sept. 18, according to testimony at Senate estimates hearings this week. The messages sat unread while Australians lost access to emergency services during what officials are now calling a deadly breakdown in both corporate responsibility and government oversight.
“Official gets an email that says there is a problem with triple zero. It should have raised alarm bells,” said Senator Sarah Hanson-Young during parliamentary proceedings. “Now Optus has clearly failed here. Optus have failed to put safety first.”
The network failure has triggered demands for a full parliamentary inquiry and exposed gaps in Australia’s telecommunications emergency protocols at a time when the country heads into bushfire season. Opposition lawmakers and government critics say both Optus and federal officials share blame for the disaster that left families unable to reach help during medical emergencies.

Prime Minister Anthony Albanese confirmed the deaths during a joint press conference with Singapore Prime Minister Lawrence Wong, who was in Canberra for his first official state visit as prime minister.
Wong offered condolences and pledged Singapore’s full cooperation in the investigation, noting that Singtel, the Singaporean telecommunications giant that owns Optus, will work with Australian authorities to prevent future outages.
“I have expressed my views in an interview recently on the outage,” Wong said. “Company Optus and its parent company Singtel operate commercially, but we expect them to behave responsibly and to comply with domestic laws wherever they operate.”
Email Breakdown Compounds Crisis
The revelation that government officials missed critical notifications has added another layer to the growing scandal. Senate estimates learned the department failed to monitor the email account where Optus sent its Sept. 18 warnings, leaving officials unaware of the emergency services disruption for an undetermined period.
Hanson-Young, a Greens senator, said someone in the minister’s office should have escalated the alert immediately upon receiving word of a triple-zero outage.
“I am concerned that if minister’s officers are receiving emails that are alerting the minister to the fact that there’s a triple zero outage, someone should have escalated that,” she said. “Why wasn’t that? Why didn’t somebody pick up the phone and call Optus?”
Shadow Defence Minister Angus Taylor said the email failure represents government incompetence layered on top of corporate negligence.
“The fact that the government wasn’t checking its email addresses is a real issue that it needs to answer serious questions about,” Taylor told reporters. “There seems to be incompetence laid on incompetence here, and part of that is the incompetence of the government.”
Taylor added that the incident raises serious questions about accountability “because people lost their lives.”
Calls for Parliamentary Inquiry Intensify
Hanson-Young announced plans to push for a comprehensive Senate inquiry when parliament resumes, arguing that Australia needs stronger telecommunications regulation and enforcement.
“That is why we need a full-blown parliamentary inquiry into this deadly fiasco,” she said. “We need to have Optus now in front of a Senate committee to answer a bunch of these questions so that we can get to the bottom of what really happened and make sure we can put in place a system that is properly regulated and puts people’s safety first.”
The senator outlined a reform agenda that includes better regulation, stronger penalties and what she called “a watchdog with teeth.”
“We need better regulation, stronger regulation, stronger penalties and a watchdog with teeth,” Hanson-Young said. “We’ve got the regulator coming up this afternoon and we will be asking them some tough questions as well.”
She said today’s evidence demonstrates the need for broader parliamentary scrutiny beyond routine regulatory oversight.
“It’s quite clear that today’s evidence shows there needs to be a much broader parliamentary inquiry,” Hanson-Young said. “And as soon as the Senate resumes, we will be moving to make sure that happens.”
Singapore Pledges Support for Investigation
Wong, whose government owns Singtel through the state investment firm Temasek, said he understands public anger over the outage and promised full cooperation with Australian investigators.
“As I’ve said before, I understand fully the anger, frustration and outrage at what has happened,” Wong said. “Because if this were to have happened in Singapore, I would feel the same.”
The Singaporean leader extended condolences to families affected by the outage, calling the deaths tragic.
“I’ve extended my condolences to those impacted by the outage, including the family members and loved ones of those who lost their lives, which is tragic,” Wong said.
Wong said Singapore expects its companies to operate responsibly in foreign markets and comply with local laws wherever they do business.
“From a government’s perspective, we expect our companies to act responsibly,” he said. “And we will certainly expect Singtel and Optus to comply fully with the laws to do whatever they can to cooperate with the investigation.”
He expressed confidence that investigators will reach conclusions quickly and implement corrective measures.
“I’m sure they will do so and hopefully a conclusion will come through very soon on the outcome of the investigation, what went wrong and steps can be taken expeditiously to rectify the mistakes,” Wong said.
Independent Review Underway
Albanese said an independent investigation is examining the network failure and searching for ways to prevent similar incidents.
“The independent investigation will be undertaken and we need to make sure that the failure by Optus in this case doesn’t happen again,” Albanese said. “It’s as simple as that and we will work to ensure that that is the case.”
The prime minister discussed the outage during his bilateral meeting with Wong, thanking the Singaporean leader for his support.
“I raised the issue and we had a discussion,” Albanese said. “I thank Prime Minister Wong for the condolences that he offered to the families and his support for strong follow-up action.”
The network failure occurred during what officials described as a routine outage, though details about the scope and duration of the disruption remain unclear. The incident has raised urgent questions about telecommunications resilience as Australia approaches its annual bushfire season, when emergency communications become critical for public safety.
Political Pressure Mounts
The crisis has created political headaches for the Labor government, with opposition lawmakers demanding answers about why officials failed to respond to Optus warnings and what safeguards exist to protect emergency services.
Hanson-Young criticized Optus for prioritizing profits over public safety, saying the company relegated safety concerns to the bottom of its priority list.
“They put safety at the bottom of the list while they thought about their profits and their shareholders,” she said. “That is not good enough.”
Taylor declined to say whether he would support a government bailout if Optus faced financial consequences from the incident, instead criticizing Labor’s broader policy approach to telecommunications and energy.
The outage revelations emerged during the same week that Albanese and Wong announced an upgraded Comprehensive Strategic Partnership between Australia and Singapore, marking 60 years of diplomatic relations and 10 years of the original strategic partnership.
The upgraded agreement includes enhanced defense cooperation, economic resilience measures, climate action partnerships and increased collaboration on artificial intelligence and emerging technologies. Ministers from both countries signed memorandums of understanding covering defense cooperation, economic resilience and regional development partnerships.
But questions about the Optus crisis threatened to overshadow the diplomatic achievements, with reporters pressing both leaders about telecommunications accountability and emergency preparedness during the joint press conference.
The deaths linked to the network failure have amplified public concern about telecommunications reliability and government oversight of critical infrastructure. Families unable to reach emergency services during medical crises have highlighted the life-or-death stakes of network stability in an increasingly connected society where traditional landlines have largely disappeared.
As investigators work to determine what caused the outage and why warnings failed to reach appropriate officials, lawmakers are preparing for what could become one of the most significant parliamentary inquiries into telecommunications safety in Australian history.
The incident underscores broader questions about corporate accountability, government regulation and the vulnerability of digital infrastructure that millions of Australians depend on for basic safety services.
