The Government of Western Australia (WA) has revealed a master plan for the Anketell Port multi-user and multi-commodity deep water port in the Pilbara region.

WA Premier and State Development Minister Colin Barnett has announced the master plan, which has been jointly developed by two government agencies, the Department of State Development and the Dampier Port Authority.

As part of the master plan development, the agencies have carried out extensive consultation with stakeholders, including LandCorp, Main Roads, the Shire of Roebourne and industry.

Explaining that access to port space was an increasingly rare and valuable commodity in Pilbara, Barnett said: "Development of Anketell Port will help to unlock the potential of the West Pilbara by aiding further development of the state’s natural resources."

"Provisions are made in the master plan for a substantial infrastructure corridor…to support port activities and future mining operations."

"This master plan is a clear guide for proponents who are seeking additional routes to bring ore to market," Barnett said.

"This may well be the last major new port in the Pilbara."

Provisions are made in the master plan for a substantial infrastructure corridor and more than 800ha of industrial land, to support port activities and future mining operations.

Proposed to be built on the West Pilbara coast 30km east of Karratha, the Anketell Port site would have a capacity of about 350 million tonnes annually, which is around 20% more than the total shipments through Port Hedland during 2012 to 2013.

The Anketell deepwater port plan has already received initial environmental approvals and a native title agreement, while an aboriginal heritage survey is currently being conducted.
