Island ecotourism has become a significant branch of tourism as it is concerned with visitors experiencing natural environments without threatening their viability. However, it is vitally important that full and careful evaluation be made of the true impact of tourism in such circumscribed environments to avoid misplaced optimism and support being given to inappropriate development. This paper discusses the impact of tourism in Australia's largest World Heritage listed island ecosystem, but also one of its oldest Island Resorts, Fraser Island Queensland. Tour operators were surveyed in order to shed light on current and future development pressures on the island from an operator's point of view. Tour operators and resort owners have developed ecotourism strategies that have significant implications for the environment of the Island, but feel that these are in danger of compromise from the impact of tourists allowed uncontrolled access by the Government Department nominally responsible for their activities.
