Establishing coordinated cadastres: Australian experiences

This is a preprint of a paper from the International Conference on Cadastral Reform, Korea, 16-17 July, 1996.Australian cadastral systems have been strongly influenced by the historical settlement of the Australian states and territories. An important consequence is that no cadastral office was ever established and as a result a coordinated cadastre never developed. Departments of Lands or Surveyors General departments administered the ever decreasing Crown lands as a result of rapid alienation, as well as the jurisdictions' surveying and mapping infrastructure. As a result Australia lacked a European style cadastral office providing a complete cadastral record which could be used for land administration purposes. Land Titles Offices historically had the responsibility for all freehold or private lands, which now comprise the vast majority of land parcels in the states. These Offices have been responsible for examining all cadastral surveys and ensuring appropriate regulations for such surveys, however they have only ever been concerned with individual transactions in support of an efficient land market. The maintenance of the cadastral map for each jurisdiction however has usually remained under the control of the Surveyor General or in recent years a geographic information coordination agency. Increasingly the title register in each jurisdiction is including all Crown and government lands and is assuming the role of a European cadastre, albeit the cadastral index has legal significance since it is based on actual land titles. Due to computerisation of the titles register and the establishment of digital cadastral data bases (DCDB), the trend in Australia is for the textual and spatial components of the cadastre to come together technically and administratively. This has allowed Australian jurisdictions for the first time to have a complete cadastral record to support land administration. The resulting model has permitted Australia to move from a land administration structure that was conceptually well behind that of most developed and many developing countries to a position at the forefront of developments due to innovation and computerisation. The development of coordinated cadastres formed by upgrading the now complete DCDBs in Australia is the key in the future improvement of Australia's cadastral systems. This paper reviews this development and shows how the Australian systems differ from their European counterparts. It concludes by attempting to describe a future conceptual model for an Australian state wide geographic information system based on a legal cadastre. Australian states and territories are well advanced to achieving this vision.16-17 July, 199
