About Thiess

Thiess works with clients in Australia, Asia and the Americas in the dynamic field of open-cut and underground mining. At our core is the pioneering spirit of the legendary Thiess brothers. Their vision defined firsts, unlocked possibilities and found smarter ways to scale what mattered to society. Almost 90 years on, their story is still in our DNA. We’ve always thrived amid change. Today, that includes rising to the challenges of climate risk and the opportunities abounding in the global energy transition. We recognise the world needs mined commodities to achieve the economic, social and environmental transformation it desires. That’s why the world needs mining…reset for the future. Thiess is committed to being at the forefront of sustainable mining, leveraging the power of its people and technology to support clients in their journey to more sustainable enterprises.
