Property boundaries represent the extent of ownership of an address in line with NSW Valuer General for the purposes of address verification and rating. The spatial layer is derived from land parcel boundaries (cadastre) originally supplied by NSW Spatial Services who remain the source of cadastral information. See SIX maps   This spatial layer has been significantly changed and maintained by City of Sydney Spatial Services.    This layer is not survey accurate.  Geoservice API disabled, but geojson and download permitted.
