Governments of most countries have land administration arrangements in place that provide a legislative framework within which decisions about the land can be made. Governments collect and maintain data that can be used for fiscal purposes, allocation of land, controlling land use, etc. In countries like Australia where there are many levels of government with often significant overlap of function we would expect to see major overlap of the types of data being collected. This paper aims to overview land information systems in Australian context with a particular focus on the systems in New South Wales.
