Cadastral Surveying

Cadastral surveying involves determining existing and creating new property boundaries. Reliable cadastral information is critical for sub-dividing land and determining ownership and rights, restrictions, and responsibilities for a land parcel.

In South Australia, cadastral surveying is regulated by the Survey Act 1992 and only a licensed surveyor can carry out a boundary survey or place a survey mark to define a property boundary.

 The Survey Operations Unit:

  • sets Notices, Directions and Guidelines containing instructions for land surveying  in South Australia
  • ensures the state’s cadastral system’s integrity by monitoring compliance with legislation, standards and guidelines
  • reports surveyors’ levels of compliance to the Surveyors Board of South Australia
  • provides advice to the profession and government agencies on complex boundary matters
  • educates the profession about non-compliance. 



We acknowledge and respect Aboriginal peoples as the state's first peoples and nations, and recognise them as traditional owners and occupants of land and waters in South Australia. Further, we acknowledge that the spiritual, social, cultural and economic practices of Aboriginal peoples come from their traditional lands and waters, that they maintain their cultural and heritage beliefs, languages and laws which are of ongoing importance, and that they have made and continue to make a unique and irreplaceable contribution to the state. We acknowledge that Aboriginal peoples have endured past injustice and dispossession of their traditional lands and waters.
