Appendix II of this paper contains the three questionnaires which were used experimentally as a part of three surveys to assess the economics of conserving Australia’s tropical wildlife species. The body of this paper outlines the procedures used for the surveys, discusses response rates and the representativeness of the samples, and outlines the general coverage of the surveys/questionnaires. The surveys provided data about participants’ knowledge of each of the focal species, their support for the survival of each, their willingness to pay for the conservation of each and their attitudes to the commercial harvesting of each. The survey procedures enabled particular attention to be given to the influence on these variables of variations in the knowledge of survey participants about the species being evaluated. In addition, information was gathered about the attitudes of survey participants towards the use of wildlife species by Indigenous Australians (Australian Aborigines and Torres Strait Islanders).
