The Wilderness Society is calling for a moratorium on the construction of liquid natural gas plants, off the Kimberley coast in Western Australia.

The demand comes after the society conducted an aerial survey that showed hundreds of whales would be threatened by the development.

They're appealing to Kevin Rudd to step in and to declare the area a marine sanctuary zone.

2SER’s Nic Christensen spoke with Josh Coates from the Western Australian Wilderness Society.

He began by asking him about the aerial survey of the Woodside Petroleum development at James Price Point.
