Opposition leader Angus Taylor has stepped in to defend Liberal senator and shadow communications spokesperson Sarah Henderson, after she made two test calls to the triple zero emergency number during Wednesday's Telstra outage that crippled services nationwide — drawing sharp condemnation from the federal government and reigniting a fierce political brawl over the crisis.
What Henderson did — and why it sparked controversy
As Telstra's network buckled under a widespread outage that also triggered a secondary triple zero fault, Henderson placed two calls to the emergency line on Wednesday in what she described as an effort to determine whether the system was functioning. The Victorian senator argued her role as shadow minister gave her a responsibility to test the service first-hand.
"I was simply, as the shadow minister for communications, making those initial calls to work out whether the system was actually operating," she told Sydney radio station 2GB on Thursday morning. "I accept the criticism, but what I will say is that I am in a unique position holding this government to account."
However, making false or improper calls to triple zero is a Commonwealth criminal offence carrying a maximum penalty of three years in prison, and Labor wasted no time in branding Henderson's conduct reckless and irresponsible.
Industry and Innovation Minister Tim Ayres was unsparing in his assessment. "I was absolutely shocked by that revelation. I just say to Australians, don't do what she did," he said. "It's utterly irresponsible. I just don't know why anybody would do that, but I'd certainly say nobody should follow her example."
Taylor hits back, turns fire on Communications Minister
Far from distancing himself from Henderson, Taylor used a press appearance on Thursday to mount a robust defence of his colleague and redirect attention squarely at Communications Minister Anika Wells.
"If [the minister] hadn't been absent for seven hours, Sarah wouldn't have had to do these things," Taylor said. "These actions were not illegal, and they were made necessary by complete and utter failure from this minister — and that should be the focus of the press, and it should be the focus of the nation."
Taylor dismissed suggestions that the calls amounted to vexatious or hoax calls, insisting Henderson was performing her duties as the Coalition's communications spokesperson. Opposition regional communications spokesperson Anne Webster also backed Henderson, arguing that the shadow minister needed to know whether the system was working.
Wells, for her part, indicated her immediate priority was restoring services, while flagging that investigations and potential penalties could follow once the immediate crisis had passed. "And then investigation can take foot, and we can learn out of that, and penalties can be administered, justice can be served," she said.
The scale of the triple zero failure laid bare
As the political firefight played out, Telstra moved to detail the full human cost of the emergency services disruption. The company's chief financial officer, Michael Ackland, confirmed at a press conference on Thursday that 639 welfare checks had been completed after the telco identified calls to triple zero that had failed to connect — even as roughly 33,000 emergency calls did get through during the same period.
"Any one missed call is unacceptable," Ackland said, adding that the welfare check process existed precisely to follow up as rapidly as possible with anyone whose call had not connected.
Of the 639 cases reviewed:
- 230 callers responded to an SMS confirming they did not require further assistance.
- 402 cases required follow-up phone calls.
- 170 cases were referred to police for further welfare checks or assistance.
- Seven callers indicated they needed help and were passed directly to the relevant emergency services.
The triple zero failures were caused by a secondary fault that emerged separately from the main outage. Overnight work had reduced the error rate by approximately 90 per cent by early Thursday morning, and by Thursday afternoon Telstra said it had "implemented a solution" that fully addressed the issue — advising customers they could now "feel confident" calling triple zero.
What comes next for Telstra and the government
The outage, which began at around 4:30am on Wednesday, affected mobile data, EFTPOS terminals, business networks and transport services — sparking renewed calls for tougher regulation of the telecommunications sector. Some transport networks remained slow or at a standstill into Thursday as the full restoration of services continued.
Penalties for telcos that breach their triple zero obligations have already been lifted to $30 million, and Wells indicated further accountability measures could be examined once services were fully restored. Experts have pointed to the episode as evidence of how deeply critical infrastructure depends on a small number of telecommunications providers — a vulnerability that the outage, described as one of the more significant network events of 2024 in Australia, has thrown into sharp relief.
For now, the political argument over Henderson's test calls shows little sign of cooling, with both sides insisting the other is missing the bigger picture.
