Permanent survey marks
Permanent survey marks are important reference marks, so please don't disturb, destroy or remove them. Find out more below.
All permanent survey marks in Queensland are registered in the Survey Control Database (SCDB), which includes coordinates, height, access notes and other administrative information.
This information is generated mainly by the surveying industry, which supports the development, maintenance and dissemination of Queensland's surveying and mapping infrastructure.

Interference with survey marks
Permanent survey marks are important reference marks that should never be disturbed. They are used by surveyors to support the surveying of property boundaries, road building, construction activity, mapping and other land surveys.
Disturbing or destroying survey marks affects construction projects that depend on accurate positioning and height information. This can lead to increased project costs to landholders, for example, if they ever need to get their boundaries resurveyed.
Survey marks are commonly disturbed by:
- construction or development work
- footpath and driveway upgrades
- utilities and services work
- restoration of kerb and channel
- vegetation clearing
- road construction.
If you are conducting this type of work, please take care not to interfere with survey marks.
Before starting construction works, consider using a registered cadastral surveyor to carry out a cadastral search of the construction area. This will show whether there's the potential to interfere with survey marks.
If your project is likely to interfere with a survey mark, please contact us.
Accessing survey control information
Under the Queensland Government's open data initiative, we have published survey control information through the Location category globe in the Queensland Globe. Survey control reports of marks are free and include the permanent survey mark plan. Read the information about the survey control functions when you are in the globe.
Alternatively if you know the number of a permanent mark, it is possible to access the Survey Control Report (with sketch) directly from any standard web browser, including on mobile devices. The Survey Control Report URL needs to contain the six digit permanent mark number, including any leading zeros. For example, for PM number 1234 the URL is: http://qspatial.information.qld.gov.au/SurveyReport/SCR001234.pdf (PDF, 71KB)
The Survey Control Register file on QSpatial contains all data from current records of the SCDB, as well as ellipsoidal heights and positional uncertainties where available. This data is available for free bulk download.
SCDB can be accessed from most of our business centres. A range of reports are available. Contact us for more information.
Copies of original survey field records can be obtained from the SCDB manager. Email CadastralAdminDataHelp@dnrme.qld.gov.au.
Submitting survey mark information
New permanent mark forms
Details of new permanent marks must be provided to the Department of Natural Resources, Mines and Energy on 1 of the following forms:
- Form 6 v.5 - New permanent marks (DOC, 66KB)
- Form 6 v.5 - New permanent marks (PDF, 1.1MB)
- Form 6 v.5 - New permanent marks (drawing file) (DWG, 37KB).

Maintenance of permanent survey marks
Email CadastralAdminDataHelp@dnrme.qld.gov.au with any updates to existing permanent marks or information about any irregularities observed in the field. Please submit information using:
Submitting Global Navigation Satellite System (GNSS) data
Control surveys must comply with the Intergovernmental Committee on Surveying and Mapping (ICSM) standards and practices for control surveys.
For a permanent survey mark to be recognised as a horizontal datum mark in the SCDB, it must be included in the Queensland State Adjustment (known as ANJ). ANJ is an amalgamation of measurements/adjustments from the hierarchy of datum.
