Geoff Mosley has worked for decades to protect wild places in Australia. He helped establish wilderness zones and parks across the south east of the mainland and Tasmania, and has recently released a book on Antarctica. He is active in the field of steady state economics, a keen walker, and widely published activist and thinker.
Perhaps he is best known for his efforts to see a major national park established across the Australian Alps. Much of this vision has now been realised, although he continues to work to see an extension of the Western section of the Alpine National Park and to get World Heritage listing for the forest ecosystems of the south east corner of the country, where Gippsland and NSW meet.
