Cadastral (boundary) surveying relates to land ownership, measurement and definition of property boundaries.

Cadastral surveys are performed for the re-establishment of existing property boundaries or for the creation of new property boundaries for land divisions. In South Australia, only licensed surveyors may undertake a boundary survey or place a survey mark that defines a properties’ boundary.

The Surveyor-General is the statutory authority for land surveying and cadastral boundaries in South Australia, and is responsible for issuing survey instructions in the form of Regulations, notices, directions, and guidelines for licensed surveyors. The Surveyor-General monitors licensed surveyor's compliance with survey instructions to ensure integrity of the State's property boundaries.

Cadastral surveying in South Australia is regulated by a four-tiered structure, the components being:

Plan Presentation Guidelines detail the Registrar-General's plan requirements.

The Surveyor-General's Survey Operations Unit maintains the State's Survey Mark Database (SDB). The SDB can be accessed on the South Australian Property and Planning Atlas (SAPPA) and the South Australian Integrated Land Information System (SAILIS).
