About Us

Lyon Group is an Australian-based independent partnership established in 2003 by founders David Green, Nicholas O’Day and Vanessa Sullivan. Lyon is the only company of its kind in Australia.

Lyon was established to focus on the investment opportunities at the nexus of the energy, carbon, water and agricultural sectors.

We bring innovative solutions to the opportunities and challenges of a changing climate and economy.

Lyon’s founders have arranged debt and equity financing and structured over $10 billion worth of energy and infrastructure projects. They each have more than 20 years of renewables and energy market experience spanning Japan, other parts of Asia, Australia and Europe.
