The West Australian quoted KLC executive director Wayne Bergmann as saying in a letter to Western Australian Premier Colin Barnett that he believed Inpex had made its decision as early as May this year, but delayed the announcement to "maximise its leverage" in talks with the WA and Northern Territory governments.

He said the KLC's extensive dealings with Inpex had convinced the body that Inpex was not committed to achieving responsible development.

"The KLC believes that Inpex's approach to its development options clearly reflects a desire to avoid environmental and native title regulation," Bergmann added.

Bergmann also raised concerns that the premier had not been briefed with all the relevant information regarding KLC's negotiations with Inpex.

"For example, at no time did traditional owners or the KLC reject an offer from Inpex of $1 billion over four years."

The KLC director is also seeking a meeting with Barnett after the premier said last week that former state development minister Eric Ripper's decision to give Aboriginal groups the right to veto the project was the last straw for Inpex.

Barnett said yesterday that he will consider next week whether to scrap the task force investigating possible locations for an LNG hub in the Kimberley region.

"I'm not necessarily critical of the task force but they had a job to do and that was to find a site for a real live project, the Inpex project," the West Australian quoted him as saying.

"They failed to do that [and] that's why I'm not particularly impressed. However, I will take on board the good work, where there is good work, that they've done."
