Singtel-owned Optus named non-executive director John Arthur as chair of its board to replace Paul O’Sullivan, who resigned after a decade in the role.

O’Sullivan was MD of mobile at Cable and Wireless Optus when Singtel acquired it in 2001. He served as COO at Optus before becoming CEO in 2004, and from 2012 to 2014 was CEO of Singtel’s consumer group. He was appointed chair at Optus in 2014.

Singtel group CEO Yuen Kuan Moon stated, “We would like to extend our deep gratitude to Paul for his years of service and stewardship, bringing more choice and innovation to customers, while strengthening Optus’ place in the market.”

Arthur joined the Australian operator’s advisory committee in July 2019 before becoming a board member. He also has been on Singtel’s board and served as a director to the Singapore company’s ICT unit since 2022.

Andrew Parker joins Optus seven-member board as a non-executive director and will take over from Arthur as head of the audit committee.

Optus is the second-largest operator in Australia, with 10.7 million subscribers, behind Telstra with 12 million.
