Land administration in Australia is a state or territory responsibility. Consequently there are eight separate systems of land titles registration in Australia and eight separate surveying and mapping systems even though there are many similarities between them. Many of the principles and concepts underlying Australian cadastral systems are based on English
common law (Williamson and Enemark, 1996). In the process the system of land transfer that evolved under English common law has been adapted to the needs of a vast newly developing country.
