Stanwell Corporation announced the leadership change in a statement uploaded to its website on Monday, but did not distribute the news through its media email list or social media accounts, and neither Treasurer David Janetzki nor Finance Minister Ros Bates, the government's shareholding ministers, promoted it more widely.
Board chair Justin Parer, a former Young LNP president who moved into the role from a port authority appointment last October, thanked O'Rourke for his leadership.
"Michael has played an important role in guiding Stanwell through a period of considerable change, strengthening the business and helping position it for the future," Parer said in the corporation's statement.
Janetzki also praised O'Rourke, who was appointed chief executive in November 2021 after joining the company in 1998. His total remuneration package was $1.1 million in the 2025-26 financial year.
"Michael is a highly regarded figure in the energy sector and has made a significant contribution," Janetzki said in the statement.
Chief operating officer James Oliver will act in the role temporarily, with O'Rourke's assistance, while a formal recruitment process is undertaken.
Stanwell operates two of the state's largest coal-fired power stations, at Stanwell near Rockhampton and at Tarong, along with battery and wind farm interests. O'Rourke's predecessor, Richard Van Breda, resigned days after remarks pointing to the possible early retirement of the coal plants.
The change comes amid the LNP government's pivot of energy focus from renewables back to fossil fuel generation, and a broader overhaul of boards across the sector. A Queensland Audit Office report earlier this year noted "almost all board chairs and 76 per cent of board roles" had turned over since the election, warning about a loss of corporate knowledge.
O'Rourke, Janetzki's office and Stanwell were contacted for comment.
