Carroll also held senior roles at Woodside Energy and BHP. He will chair the Ethics and Governance Committee and join the Audit and Risk and Technical Committees.
The board’s committee composition has been updated to reflect these appointments, with Carroll now chairing the Ethics and Governance Committee and Mr Tremaine chairing the Audit and Risk Committee.
