Who we are and how we came about
Aluminium is increasingly becoming the world’s metal of choice.
Tomago Aluminium Company
Tomago Aluminium is Australia’s largest aluminium smelter and has been operating 24 hours a day since 1983.
The company contributes $2.2 billion annually to the Australian economy, of which $800 million is spent locally. The smelter produces 590,000 tonnes of aluminium every year, which is 37% of Australia’s primary aluminium. 90% of the product made at Tomago is exported to the Asia-Pacific region.
Tomago Aluminium company is an independently managed joint venture. Joint Venture partners are Rio Tinto, CSR and Hydro Aluminium. The owners provide raw materials to Tomago that are converted to aluminium at the Tomago plant. The product is supplied back to the owners who then take it to market.
Tomago employs 1000+ staff (full time equivalent) as well as 200 contractors. Our staff are drawn from a significant geographic area throughout the Hunter Valley and Central Coast travelling from as far as 100km south, 80km north and 50km west of the plant. Ensuring that our people are safe while they are at work is one of the main drivers of our business.
Aluminium is increasingly becoming the world’s metal of choice as it is sustainable for environmentally conscious economies. It is also versatile and is used in the production of cars, planes, homes, sporting equipment, and so much more. It is Australia’s fifth largest export commodity.

How much energy is used by Tomago Aluminium?
Aluminium production relies on electricity to power the process 24 hours a day, 365 days a year. The production chain never stops. Tomago Aluminium uses around 10% of the New South Wales power supply to produce 590,000 tonnes of aluminium per year.
