This extensive report describes activities of the PEACESAT AUSTRALIA Project (the Kangaroo Network) which parallels, on the Australian continent, the endeavors of PEACESAT (Pacific Educational and Communication Experiment by SATellite), and other Pacific Basin ATS-1 networks. An executive summary reviews the development of the project and its philosophy and objectives, which include using a network of low-cost ground terminals to give small users an opportunity to discover effective satellite applications. Also described are the network and subnetworks, network coordination, access procedure, scheduling, access to other ATS-1 networks, application and technical experiments, the experimenters, technical matters, evaluation, and plans for 1984. Additional chapters provide details on sites, their institutions, and their status; geographical location; project membership, institutions, and personnel; and project subnetworks. Also included are a Kangaroo Network weekly schedule and priority times; ATS-1 weekly schedule; sample list of experiments and experimenters; list of ground station equipment; four institutional proposals for 1984; list of 31 publications; and miscellaneous items relating to current activities. An annex, "ATS-1 in Perspective," discusses the ATS-1 satellite, current usage of ATS-1 in Australia, the advantages and disadvantages of ATS-1, prospects for use of two Australian domestic satellites scheduled for launch in 1985 (AUSSAT), and conclusions. A 10-item reference list is provided. (LMM)
