Our History_vintage Coffey

Our history

We’ve been breaking new ground since the very beginning.

When David Coffey saw the potential for geotechnical engineering in the 1950s, it was a little understood discipline that was rarely used in Australia. Seeing its value, David travelled to Canada where he lived and worked, honing his craft and building his skills as a geotechnical engineer.

Returning to Australia in 1959, he launched Australia’s first geotechnical engineering firm, and Coffey was born bringing innovation and insight to projects throughout Sydney. It took just four years for Coffey to lead the market, edging out competitors that had arrived from overseas. By the mid-1960s, we were working across Australia and continuing to grow.

In the 1970s, Coffey ventured overseas, creating new opportunities for the company. But it was during the 1980s that Coffey really expanded. New work saw us grow, while strong financial management ensured stability. In 1990, Coffey International Limited was listed on the Australian Stock Exchange. We spent the following decade steadily growing as we transitioned from a private to public company and further developed our reputation for technical excellence. In the early 2000s, we embarked on a range of acquisitions, diversifying the company beyond its traditional origins.

In 2016, we joined Tetra Tech a leading provider of consulting and engineering services with 28,000 associates working across the full project lifecycle. We are now involved in more worldwide industries than ever before. Across Australia and New Zealand, our operations include more than 550 employees located throughout the Pacific. In our region we work alongside Tetra Tech Proteus, Eco Logical Australia, A Tetra Tech Company, Norman Disney & Young, A Tetra Tech Company and RPS, A Tetra Tech Company who bring long-established successes delivering practical and sustainable services for our clients.
