Over 25 years, he has discovered several new orchid species and published more than 45 scientific papers relating to native orchids and other plants of conservation significance. Like most orchid enthusiasts, he loves nothing more than getting out into the bush and finding and photographing native orchids in their natural habitat.

He has travelled to most of the major centres for orchid diversity around the world and has photographed over 5000 species of orchids in the wild. Gary is author or co-author of three books on native orchids of Victoria and a book on Caladenia orchids of Australia.
