Optus Network Outage Disrupts Dozens of Triple Zero Emergency Calls Across Australia

Triple Zero Victoria said the 39 affected Victorian calls occurred shortly before 7 p.m., while Optus said it first became aware of the outage at about 1:30 p.m. AEST and immediately mobilised technical teams.
Optus said the fault affected voice-calling capabilities for some customers in regional areas and apologised for the disruption, stating: “We sincerely apologise to our customers for the disruption.”
Updated emergency-call guidance says callers should retry if their first attempt fails and remain on the line for up to a minute; the line may be silent while the phone searches for another available mobile network.
A previous Telstra outage prompted 639 welfare checks, seven of which resulted in assistance, underscoring the wider impact of carrier failures on emergency access beyond the current Optus incident.
Communications Minister Anika Wells said she would “hold Telstra’s feet to the fire” over its response to an earlier disruption, while calling for Australia’s telecommunications legislation and regulations to be rebuilt to make them “fit for purpose.”
Optus suffered a 76-minute network outage on Monday evening that disrupted at least 42 Triple Zero emergency calls across four Australian states. AAP News reported that police conducted welfare checks on 39 callers in Victoria and three in Tasmania after their emergency calls failed to connect. The company said a technical fault affecting voice calls was identified and repaired, but the incident has intensified debate about Australia's telecommunications resilience.
The outage affected Victoria, South Australia, Tasmania, and the Northern Territory, with Optus saying it became aware of the problem around 1:30 p.m. AEST and immediately mobilised technical teams AAP News. Authorities confirmed that those contacted during police welfare checks did not require immediate assistance, but the disruption has renewed scrutiny on the company's network reliability and emergency call infrastructure.
Market Screener reported that Australia's No. 2 telecom carrier experienced a technical glitch causing the 76-minute disruption. Optus confirmed the fault affected voice-calling capabilities for some customers in regional areas and issued an apology. The company said: "We sincerely apologise to our customers for the disruption." Voice calls gradually returned to normal once the technical team repaired the underlying issue.
Emergency call guidance has been updated to help residents navigate carrier failures. Callers should retry if their first attempt fails and remain on the line for up to a minute. The phone may fall silent while it searches for another available mobile network. Emergency calls may also connect through another carrier's network or Wi-Fi when available, providing backup pathways during outages.
This is Optus's second major outage in a year, adding to broader concerns about Australian telecommunications reliability. AAP News noted that a previous Telstra outage prompted 639 police welfare checks, seven of which resulted in actual assistance. The wider impact reveals how carrier failures can endanger vulnerable people who cannot reach help. Each incident underscores systemic weaknesses in emergency call infrastructure.
Optus faces separate legal jeopardy over an earlier failure that allegedly blocked 1,005 emergency calls, with potential penalties exceeding $500 million. Communications Minister Anika Wells said she would "hold Telstra's feet to the fire" over its response to past disruptions and called for Australia's telecommunications legislation to be rebuilt to make it "fit for purpose."
The repeated outages have prompted calls for stronger oversight and resilience requirements across Australia's telecom sector. Officials are examining how carriers can better protect emergency access during network failures. Regulators are expected to review whether current penalties and enforcement mechanisms are tough enough to drive real change. The government is signalling that new telecommunications rules may be needed to prevent future incidents.
