Boyne Island Aluminium Smelter, commonly known as Boyne Smelters Limited, is one of Australia largest aluminum smelting facilities, located in Queensland. Although recorded here under the United Kingdom, the smelter operates in Boyne Island near Gladstone and plays a critical role in global aluminum production. The facility produces primary aluminum used in transportation, construction, packaging, and industrial manufacturing. Operated as a joint venture with Rio Tinto as the majority stakeholder, the smelter integrates large scale electrolytic reduction technology powered by dedicated energy infrastructure. Boyne Island Aluminium Smelter is recognized as one of the Southern Hemisphere most significant aluminum production assets. Its operations support export driven metal supply chains and contribute substantially to regional industrial employment and infrastructure development.

Boyne Island Aluminium Smelter was commissioned in 1982 in Queensland, Australia, as part of a strategic expansion of aluminum production capacity. The facility was developed to leverage regional energy availability and port access.

Expansion phases during the 1990s significantly increased production capacity, establishing the smelter as a major aluminum supplier in the Asia Pacific region. Infrastructure modernization initiatives strengthened operational efficiency during this period.

Throughout the 2000s and 2010s, the smelter underwent technological upgrades focused on energy optimization and emissions reduction, reinforcing its long term industrial viability.
