Permanent Survey Marks (PSMs) are valuable State geodetic infrastructure that underpin the surveying of property boundaries, development and construction activities, mapping and environmental monitoring. PSMs hold accurate coordinate and height information and provide the geodetic reference frame for surveying activities. PSMs enable surveyors to readily identify property boundaries and comply with legislation and project requirements, which improves the efficiency of surveying activities, reducing costs for industry and the community.

• is responsible for establishing and maintaining a network of PSMs, providing reliable reference points for surveyors to determine property boundaries and establish positioning for construction, mining and mapping
• maintains an enquiry system for survey mark information (South Australian Property and Planning Atlas - SAPPA).

Under the Survey Act 1992, a PSM must not be disturbed without prior approval of the Surveyor- General. There is provision under the Act for fines of up to $2000 per PSM disturbed, damaged, removed or destroyed.
