Overview

• Emergency calls were disrupted for Dapto-area customers between about 3:00am and 12:20pm on Sunday after a mobile tower fault.
• Optus says roughly a dozen Triple Zero call failures were identified, with nine resolved by midnight and several referred for NSW Police welfare checks.
• Following checks with police, Optus says all people who attempted to contact emergency services are OK.
• The telco has restored service, issued an apology, and says it is working with police and investigating the cause, which remains unidentified.
• The incident comes weeks after a firewall upgrade failure blocked about 600 Triple Zero calls and was linked to multiple deaths, prompting an independent review led by Kerry Schott and a scheduled meeting between Communications Minister Anika Wells and Singtel leadership.
