Speaking at a public forum on the Burrup over the weekend, State Development Minister Clive Brown said he was pleased representatives of the Liberal, One Nation and Greens WA parties had declared their support for the projects.

"Prior to today's meeting, it had not been clear whether the other political parties supported the projects," Mr Brown said.

"Now that that matter has been settled, the only point of contention relates to the exact location of the projects."

The Minister noted that the Greens advocated transferring the $6billion of planned development from the Burrup to the Maitland Estate.

"The case for transferring all industry from the Burrup to Maitland ignores the reality that the companies considering investing $6billion on the Burrup have already expended millions of dollars in feasibility studies," he said.

"To ask them now to move more than 20km away, to a place where there is absolutely no infrastructure, not even a road, would not only drive them out of Western Australia, and Australia, but would damage our international reputation and devastate our ability to attract world-class investment projects for many years to come.

"WA's entire resources industry has annual sales of $27billion and makes an enormous contribution to both the State and national economies, generating thousands of jobs.

"In addition, the considerable revenue generated for the State enables the State Government to meet the community's ongoing need for more hospitals, schools, police, roads and other vital infrastructure."

Mr Brown said successive governments had supported planning for development on the Burrup and had engaged in considerable community consultation to develop the formal plans.

He said he was greatly encouraged by the leadership demonstrated by the Shire of Roebourne in calling the public meeting on the Burrup.

"The Government intends to work closely with the shire as planning proceeds and throughout the development process," the Minister said.

During today's forum, Mr Brown also allayed local community concerns regarding access to the Burrup Peninsula.

"In our negotiations with the three native title claimants, the State is pursuing an agreement that ensures development proceeds on the industrial estate, that the environment and Aboriginal heritage are protected and public access is assured," he said.
