Aluminium is a lightweight, durable, and corrosion-resistant metal that is essential for low-carbon solutions. It is produced from bauxite, which is mined from bauxite rocks and then refined into alumina before being smelted into aluminium. Australia is one of the largest producers of bauxite and is known for its high-grade ore, especially in the Weipa and Gove deposits. The Weipa bauxite mine in Queensland is the largest of its kind in the world. Bauxite is primarily found in Western Australia and Queensland, with mines in Boddington, Weipa, Huntly, and Willowdale. Australia's bauxite industry is economically significant, and the country is expected to produce over 82 million tonnes of bauxite in 2016-2017.

Aluminium mines in Australia
Aluminium is critical for renewable energy generation, storage and lightweighting. It is also the third most abundant element in the Earth's crust (8.2%) and the most plentiful metal. Australia is one of the few countries with bauxite mining, alumina refining, aluminium smelting and aluminium extrusion industries. Bauxite is the primary raw material for alumina and aluminium.
In 2016-17, Australia was the world's largest producer of bauxite, accounting for approximately one-third of global production. The country had five bauxite mines, providing feedstock for seven alumina refineries. In 2018-19, Australia produced approximately 102 million tonnes of bauxite from seven main bauxite mines, generating about $3.3 billion AUD in revenue.
Bauxite is mined in Queensland, Western Australia, the Northern Territory and Tasmania. The Weipa bauxite mine on Western Cape York Peninsula in Queensland is owned by Rio Tinto and exports over 27 million tonnes of bauxite annually. The Gove mine on the Gove Peninsula in the Northern Territory is also owned by Rio Tinto and produced 12.5 million tonnes of bauxite in 2018. The Boddington mine near Boddington in Western Australia is owned by South32 and produces approximately 16.7 million tonnes of bauxite per year.
Australian Bauxite Limited has its first bauxite mine in Tasmania and produces high-grade metallurgical, cement-grade and fertiliser-grade bauxite. Queensland Alumina Limited’s bauxite is mined in Weipa, far north Queensland, and shipped over 2,000 kilometres south to Gladstone. Another small-scale mine at Weipa, Urquhart Bauxite, is expected to begin production soon.

Alumina refineries in Australia
Australia is one of the few countries in the world with a bauxite mining, alumina refining, aluminium smelting and aluminium extrusion industry. In 2019, Australia was the second-largest producer of alumina and the world's largest exporter. The country's alumina production that year was 20.5 million tonnes.
There are six alumina refineries in Australia, mostly producing smelter-grade alumina for domestic use and export. Queensland Alumina Limited (QAL) is one of the largest alumina refineries in Australia by production capacity. It is located in Parsons Point, Gladstone, Queensland, and its alumina is exported to Asia, the Middle East and the Pacific region. The Yarwun refinery in Gladstone, Queensland, produces over three million tonnes of alumina per year, which is also exported to Asia, the Middle East and the Pacific region.
Alcoa's Wagerup Alumina Refinery is one of the world's most environmentally and technologically advanced alumina refineries, producing approximately 2.8 million tonnes of alumina each year. The refinery is located in Western Australia's Peel and South-West regions, and bauxite ore is transported via an overland conveyor from Alcoa's Willowdale Bauxite Mine, located east of Waroona. Alcoa's Kwinana Alumina Refinery in Western Australia, commissioned in 1963, was the first of Alcoa's three WA alumina refineries. It produces 2.2 million tonnes of non-metallurgical alumina (15%) and smelter-grade alumina (85%) annually. The Pinjarra alumina refinery, owned by Alcoa, is located within the Shire of Murray in the Peel region, south of Perth, Western Australia. It receives bauxite from the Huntly Bauxite Mine.
South32 refines bauxite at its Worsley Alumina refinery in Australia. The bauxite is mined near Boddington in the South West of Australia and transported via an overland conveyor belt to a refinery, where it is turned into white alumina powder for export to smelters worldwide.

Aluminium smelters in Australia
Australia is one of the world's largest producers and exporters of bauxite, alumina, and aluminium. The country is equipped with bauxite mining, alumina refining, aluminium smelting, and aluminium extrusion industries. Aluminium is a crucial metal for Australia's renewable energy generation, storage, and lightweighting. It is also used in the production of cars, planes, homes, and sporting equipment.
There are currently four aluminium smelters operating in Australia, which produced 1.58 million tonnes of aluminium in 2024, with 1.50 Mt exported. The smelters are located in areas with reliable and historically low-cost electricity sources, as electricity is a key input in aluminium smelting.
Tomago Aluminium, located in the Hunter Region, is Australia's largest aluminium smelter and has been operating for 40 years. The company contributes $2.2 billion annually to the Australian economy, with $800 million spent locally. Tomago Aluminium has a diverse team with a strong focus on safety and environmental compliance.
The second-largest smelter is Boyne Smelters Limited, which has been operating since 1982. The Bell Bay smelter in Tasmania holds a unique place in Australian history as the first aluminium smelter in the Southern Hemisphere, operating since 1955. Additionally, NZAS stands out for its use of renewable hydroelectricity, resulting in a low-carbon footprint.
The Australian aluminium industry is committed to sustainability and transparency. The Aluminium Stewardship Initiative (ASI) aims to create sustainable practices across the aluminium supply chain, and the Sustainable Bauxite Mining Guidelines offer expertise in sustainable mining to the global industry.

Australia's bauxite production
Australia has been mining bauxite since the early 1960s and is a major economic player in worldwide bauxite mining. It is the largest producer of bauxite in the world, producing 31% of global production in 2016. This figure is expected to increase to 33% in 2016-17, with an estimated production of 82.7 million tonnes of bauxite. In 2018-19, Australia produced approximately 102 million tonnes of bauxite, generating $3.26 billion AUD in revenue and $1.2 billion AUD from bauxite ore exports. In 2024, Australian bauxite production was 100.20 million tonnes.
There are currently six bauxite mines in Australia, providing feedstock for the five alumina refineries and the export market. These alumina refineries, in turn, supply alumina to the four Australian aluminium smelters. The country's bauxite export volume is projected to increase at an annual rate of 3.4% from 2017-18 to 29 million tonnes in 2021-22. China dominates Australia's bauxite ore exports, taking more than 95% of total production. The Chinese economy plays an important role in the demand for aluminium, and during periods of economic growth for China, there is a high demand for aluminium, leading to increased demand for bauxite and alumina exports from Australia.
