Our story so far

Alcoa Australia has been operating in the south-west of Western Australia since 1963.

Our two bauxite mines (Huntly and Willowdale) and our three alumina refineries (Kwinana, Pinjarra and Wagerup) are among the world’s best operations of their kind and add considerable value to the national, state and local economy.

Our WA operations produce about 45% of Australia’s alumina and directly employ nearly 4,000 people. We value our place in the local communities where we operate and the value we add. In 2018, our WA operations:

  • Invested $1.4 billion with 940 Western Australian suppliers
  • Paid $600 million in wages, salaries and associated benefit
  • Paid $114 million in state and local taxes and royalties
  • Made $3.8 million in community contributions

Environmental performance

Inherent to our core values is the protection of the environment and our commitment to the highest standards of environmental performance.

We acknowledge and respect the privilege of operating in an area of Western Australia characterised by jarrah forest, native flora and fauna, and a number of waterways.

Over decades, we have acquired considerable expertise in operating sustainably and successfully in this unique ecosystem. We have also worked collaboratively with government to develop a comprehensive environmental reserve system in the Northern Jarrah Forest.

To date, less than 4% of the jarrah forest within our bauxite mineral lease – or about 1% of the total jarrah forest in the south-west – has been mined. Over the entire life of our WA operations, we expect to mine less than 8% of our mineral lease, or less than 3% of the total jarrah forest.

We do not mine in gazetted national parks, nature conservation reserves, old growth forest, or other areas of high conservation value.

Of the area we have mined, about 77% has been rehabilitated to date. The objective for our rehabilitation is to re-establish a self-sustaining jarrah forest ecosystem that fulfils forest land uses including conservation, timber production, water catchment and recreation.

Our deep understanding of jarrah forest management techniques has been developed over many years of on-site research and experience. We pride ourselves on a rehabilitation program widely acknowledged as global leading practice, by government and academics alike.

Alcoa was the first mining company in the world to achieve 100% plant species richness in rehabilitated mine site areas and we continue to lead research into innovative techniques for best-practice restoration.
