Woodside has officially applied to build and operate a liquefied natural gas plant north of Broome in Western Australia.
The state environment minister has already approved a development precinct at James Price Point.
The ABC reports Woodside has now put its application before the Environmental Protection Authority, which will accept public comment on the application for seven days.
Chief executive Peter Coleman said the company is committed to processing the gas at James Price Point because of a retention lease it signed in 2009.
He said the company is 98% through the process of reaching a decision and has so far spent $1 billion on the process.
It is due to make a final investment decision on the project next year.
