Goldsworthy, Skira to Power board

Former Rio Tinto executive Denise Goldsworthy and former Water Corporation chair Eva Skira have been appointed directors of Western Power, replacing Sharon Warburton and George Cash.

Ms Skira is a director of contractors Macmahon Holdings and RCR Tomlinson, a trustee of St John of God Health Care and a board member of the Western Australian Cricket Association.

She served as chair of Water Corporation for four years to 2016, and was also deputy chancellor of Murdoch University.

Ms Goldsworthy held roles at both Rio Tinto and BHP Billiton, including as managing director of Dampier Salt (Rio) and chief commercial officer of autonomous trucks.

More recent roles included as a governing councillor at Edith Cowan University, a director of the Export Finance & Insurance Corporation, and chair of ChemCentre.

She was also honoured as Telstra Australian Businesswoman of the Year in 2010.

Two directors will leave the board.

Sharon Warburton, who has been an executive of Multiplex and is a director of Barminco, Gold Road Resources and Perth Children’s Hospital Foundation, will leave after serving in the role since 2015.

Ms Warbuton is chair of the federal government's Northern Australian Infrastructure Facility.

Former president of the state legislative council George Cash, who was a Liberal member of parliament for 25 years, will also depart the board.

Peter Iancov retained his spot on the board, which he has held since 2015.

Mr Iancov is a director of Valmec and also of the Southern Ports Corporation.

Treasurer Ben Wyatt congratulated Ms Goldsworthy and Ms Skira on their appointments.

"I am sure that their extensive experience will be a valuable addition to the board, and will continue to enhance the governance of Western Power,” Mr Wyatt said.

"I have no doubt that the refreshed board will continue to help shape the utility to deliver the energy needs of Western Australians, while supporting the integration of new forms of generation and efficiency technologies."
