Prominent businessman and environmental activist Geoffrey Cousins says BHP Billiton's decision to sell its share in the Browse gas development near Broome is the best thing to happen to the project.
Chinese company PetroChina is set to buy BHP's interests in the east and west Browse fields.
Woodside, the consortium leader, plans to process the gas at James Price Point, north of Broome, but the escalating cost of onshore processing has seen other joint venture partners push to use floating LNG technology.
Mr Cousins says now BHP has withdrawn from the project it is more likely a processing plant will be built off shore.
"I think it's very positive and I've said previously and I say again if floating technology is used here it will be a wonderful example of technology helping to solve an environmental issue instead of creating one," he said.
