Co-Founder
Nigel Sharp
Nigel Sharp is an Australian biodiversity impact investor, conservationist, and environmental business innovator. He has dedicated his career to building and investing in nature-first enterprises - profitable businesses that deliver measurable benefits for both people and the planet.
Nigel’s passion for conservation began early, spending summers on his family farm in South West Victoria planting trees alongside his father for Soil Conservation Authority projects. These formative experiences inspired his lifelong commitment to protecting ecosystems and creating purposeful, nature-positive solutions.
Before turning fully to biodiversity recovery, Nigel built a successful career in property and funds management. Starting as a rural land valuer, he advanced to Associate Director at Knight Frank and later founded Australia Asia Investment Management (AAIM). As CEO, he led the ASX listing of Flinders Industrial Property Trust, growing it into a $300 million portfolio before its acquisition by Stockland. Until 2018, he also served as Chair of Kilter Rural, a farmland and ecosystem investment manager.
In 2001, Nigel and his wife Rosemary purchased land on French Island to regenerate remnant vegetation and protect native wildlife. Two years later, they acquired Mt Rothwell, transforming it into Victoria’s largest feral predator-free ecosystem (473 ha). Mt Rothwell became home to vital captive breeding programs and 80% of the mainland Eastern Barred Bandicoot population. Alongside ecological success, it demonstrated how conservation could create strong partnerships and a viable business model.
From these experiences, Nigel developed the 7Cs Impact Framework, an approach that balances commercial outcomes—Cashflow and Capital—with nature-positive outcomes for Creatures, Climate, Corridors, Community, and Culture. This framework now underpins the strategy of the organisations he leads.
Today, Nigel directs the growth of multiple nature-first organisations, proving that profitability and biodiversity are not mutually exclusive. His vision is clear: a future where all businesses embed nature at their core, driving financial success while actively regenerating ecosystems.
