The BHP Billiton Worsley alumina refinery near Collie produces more than 4.1 million tonnes of alumina annually and is one of the biggest alumina refineries in the world.

Thompson Surveying has been part of the Worsley team since its inception in the 1980s when we were responsible for setting out the original lease area for the refinery to be built.

Since then, we have been an integral supplier of surveying services to BHP Billiton Worsley Alumina at both its refinery and bauxite mine in Boddington. Our ability to offer the latest technology and most experienced staff to provide surveying solutions as they occur, has always held us in high regard at Worsley.

As this is a BHP site, our commitment to health, safety, environment responsibility and sustainable development has also been critical.
