Worsley Alumina is an integrated bauxite mining and alumina refining operation in the South West of West Australia. Beginning operations in 1984, it is today recognised as one of the largest alumina refineries in the world.
We are proposing the next phase of bauxite mining near the town of Boddington, providing access to future reserves and resources to sustain production at our Worsley Alumina refinery near Collie.

Worsley Alumina is a key contributor to the Western Australian economy. We are one of the largest private sector employers in the Peel and South West regions, with approximately 1,500 permanent employees and more than 500 contractors.
We inject more than AU$1 million per day into the local economy through wages, local business spend and community investment.
The next phase of mining would sustain the employment of our workforce, create approximately 150 jobs during construction, and continue to deliver socio-economic benefits to our local communities.
We are seeking State and Commonwealth approval for the Worsley Mine Development and will prepare an Environmental Review Document (ERD) in support of our application. The ERD will address all matters of environmental management relating to the project, including Matters of National Environmental Significance (MNES), and includes specialist environmental studies to address the assessment requirements and the feedback from our stakeholders.
In July 2019, the Western Australian Environmental Protection Authority (WA EPA) announced the level of assessment as a Public Environment Review, with an eight week public review for the Environmental Review Document.
In October 2019, the Commonwealth Department of Agriculture, Water and the Environment announced that it will undertake an accredited assessment, allowing the WA EPA to conduct the assessment.
Bauxite is mined near the town of Boddington, 130 kilometres south east of Perth. The bauxite is transported to the alumina refinery via an overland conveyor system that stretches more than 50 kilometres. The refinery extracts alumina using a four-stage Bayer process.
This process turns the red bauxite rock into white alumina powder. The alumina is then transported 55 kilometres by rail to the Bunbury Port for export to aluminium smelters worldwide, including South32’s Hillside and Mozal aluminium smelters in Southern Africa.
The alumina is used in the smelting process to produce aluminium. Aluminium is strong, flexible, light-weight, durable, 100 per cent recyclable. It plays a crucial role in producing lighter vehicles and other forms of transport due to its high strength-to-weight ratio.
Aluminium is resistant to corrosion and is recyclable, making it an increasingly popular choice in modern sustainable buildings. It is also widely used in machinery, packaging and electronics.
