Mining giant BHP Billiton was described as "relative good guy" and investment bankers were "radical greenies" at a protest this morning featuring iconic musician John Butler.
The Wilderness Society organised the mid-morning concert at BHP's Lonsdale Street headquarters to protest against a controversial gas plant proposed for James Price Point, in the Kimberley region of Western Australia, near Broome.
The protest was staged in front of BHP but the society's national Kimberley campaigner, Glen Klatovsky, praised the company for its 2010 comments that cast doubt on the project's future.
Mr Klatovsky said the miner's head of petroleum, Michael Yeagher, raised doubts about whether the $53 billion industrial complex should be built at James Price Point or whether an alternative pipeline should instead be built to an existing plant.
"Up to this point BHP have been the relative good guys," Mr Klatovsky told the crowd of about 100 protesters and onlookers.
He also described as "radical greenies" investment banks JP Morgan, Citigroup and Macquarie Equities as they had cast doubt on the project's financial viability.
The James Price Point project's partners include Woodside, Shell, BHP Billiton, BP, Mitsubishi and Mitsui. The project is an offshore liquefied natural gas field backed by Western Australian Premier Colin Barnett.
The Wilderness Society said the site was home to the world's largest humpback whale nursery and threatened dolphins, sea turtles and dugongs. It also boasted the longest chain of dinosaur footprints in the world, it said.
Mr Butler said his interest in the region began when he met his wife, Danniele Caruana, there 14 years ago. He said he had developed a strong friendship too with local indigenous leader and custodian Joseph Roe.
He said the proposed complex would disturb ancient burial sites.
"Literally that place is a church and culturally significant to him (Mr Roe)," Mr Butler said.
"I don't have a problem with mining so long as it is socially, morally, environmentally and politically responsible, and this is not," Mr Butler said.
Mr Butler sang Kimberley, a song about the beauty of the region, which was laced with analogies to the project.
Mr Butler, Missy Higgins, Clare Bowditch and former Greens leader Bob Brown will appear at a concert at Federation Square at 6pm.
A BHP Billiton spokesman said the company would not comment on the protest nor the project.
