Optus Chief Technology Officer and Head of the Networks Division, Tony Baird, is set to leave the company, roughly a month after an independent review into the Sept. 18. 2025, triple-zero outage linked to at least two deaths.
Baird, who joined Optus as managing director of the networks division in January 2025, is the third C-suite executive to depart since the incident.
He will be succeeded by Telstra executive Sri Amirthalingam, who will join in January 2026 and work alongside Baird during a transition period.
The independent review identified at least ten errors involving Optus Networks and contractor Nokia during a routine network upgrade in South Australia, highlighting gaps in risk management and recommending a series of reforms for the division.
