Alumina Production in Australia Industry Data and Analysis
Australia is the world's largest bauxite producer and alumina exporter. Alumina is made by applying the Bayer process to bauxite. It can then be further refined into aluminium. The Alumina Production industry is highly concentrated and has only three major players: Alcoa, Rio Tinto and South32. Each firm is vertically integrated, with upstream bauxite mining and downstream aluminium smelting operations. The industry has displayed volatility over the past few years due to production disruptions, fluctuating prices, labour shortages and erratic purchase costs. Although domestic smelters account for a significant portion of demand, most of the alumina produced in Australia is exported. Exports are anticipated to account for over 85% of industry revenue in 2025-26. This leaves the industry reliant on global markets to drive performance.
