South32 owns 86 per cent of Worsley Alumina, with 10 per cent held by Japan Alumina Associates (Australia) Pty Ltd and the remaining 4 per cent held by Sojitz Alumina Pty Ltd.
Bauxite is mined near the town of Boddington, 130 kilometres south-east of Perth. It is transported by overland conveyor to the alumina refinery near Collie and turned into alumina powder, before being transported by rail to the Bunbury port.
It is then shipped to smelters around the world, including South32’s Hillside and Mozal aluminium smelters in Southern Africa.
Operations began in 1984 and today Worsley Alumina is recognised as one of the largest alumina refineries in the world.
We have two Community Liaison Committees (CLCs) that provide a platform for open, meaningful dialogue between our operation and local community representatives.
We care about our environment, our community and our people. We’re minimising impact and rehabilitating the land we work on. We’re spending over a million dollars a day and supporting important initiatives in our local communities. We’re providing secure, flexible employment for thousands of local people.
We’re doing it for the future of the South West – for our future.
As a major employer in the South West and Peel regions of Western Australia, our operations invested on average more than A$1 million each day in FY25 into surrounding communities through wages, procurement from local businesses and community investment.
In FY25, we invested A$1.9 million in community projects across the regions where we operate, investing in projects focused on education and leadership; employment and economic development; community health and well-being; natural resource resilience; and Indigenous participation.
In FY26, Worsley Alumina will continue its Community Grants Program, which provides the opportunity for grants of up to A$5,000 (GST exclusive) for eligible local organisations, projects and programs that will provide a benefit to people in the South West and Peel communities. This program will next accept applications in February 2026.
