Leed has turned 25, and we’re reflecting on the projects, people and growth that have shaped our business. It’s also a chance to share the long-term outcomes our work has created for communities around Australia.
The Leed story started in 2001 with directors Andrew Millar, Graeme Lawler and Mark Jones, general superintendent Leigh Sutherland, and a small office in Adelaide.
Twenty-five years later, the company has grown into a national infrastructure business delivering water, civil and environmental infrastructure across metropolitan, regional and remote Australia.
The Leed Group now has almost 400 people, with offices in Adelaide, Melbourne, Bendigo and Cooma. Our core capabilities have also expanded through concrete remediation specialists Ecospec joining the group, as well as our strong partnership with Aboriginal-owned Birubi Australia. In 2026, Leed entered a new chapter by joining JN Bentley, part of the global Mott MacDonald Group.
A lasting infrastructure legacy
Over 25 years, Leed teams have delivered infrastructure that supports communities long after construction is complete.
Notable examples include:
- the Glenelg to Adelaide Parklands Recycled Water Project, which supports irrigation across more than 163 hectares of Adelaide parklands
- the new 36.2ML Shepparton Clear Water Storage Tank, a water security win for the Shepparton region
- the multi-award-winning Lake Hawdon North Regulator and Fishway project, helping create up to 1,763 hectares of endangered shorebird habitat
- the launch pad for Tunnel Boring Machine Monica at Marica in the NSW Snowy Mountains, delivered for Future Generation Joint Venture and Snowy Hydro as part of Snowy 2.0.
- the Urunga Sewage Treatment Plant upgrade, which has doubled the capacity of the previous plant.
Growing our people and capability
Leed’s growth is also reflected in our people. Thirty-one current employees have spent 15 years or more with Leed, while several have celebrated 20 years with the company during our anniversary year. Many staff have climbed the career later, including nine former Leed graduates who are now project managers and area managers.
Leed has also grown from a handful of vehicles and construction machines to an owned and operated fleet of almost 300, strengthening our ability to self-perform work across Australia.
