However, the Greens applauded the WA EPA's advice. Greens Senator Rachel Siewert said in a media release: "This is the second time the WA EPA has knocked back this proposal. The proponents should review their options to put the project on the mainland, which will ultimately be a win for the regional economy and a win for the unique environment of Barrow Island." "This is a proposal that should always have been located on the mainland. Proposing to build something on this scale inside Australia's most precious island nature reserve was deeply flawed from the beginning," said Senator Siewert. "The island has been dubbed 'Australia's Ark' for its unique cargo of endangered species, many of them now extinct or endangered on mainland Australia. He must take strong action to look after the island."
