The Australian Energy Council (AEC) and its Board has thanked Brett Redman for his Chairmanship of the Australian Energy Council over the past 17 months.
The Council's Chief Executive Sarah McNamara said: "Mr Redman brought great experience and knowledge to the AEC's Board, which has been invaluable."
"His input, guidance and support has been greatly valued not just by me in my role as Chief Executive, but also by our members during a period of significant adjustment for the industry.
"As a widely respected friend and colleague across the energy sector his contributions will be missed. On behalf of the AEC, its Board and our members, I would like to wish him well."
The AEC will be chaired by its Deputy Chair, Greg Everett, until a new chair is appointed.
