Land surveys

This page has information for surveyors and the general public on how to find land survey and land tenure information for the Northern Territory (NT).

This information can help property owners, planners, developers, local councils and government departments to get a better understanding of issues relating to different pieces of land.

There are also specialised services for professionals and companies needing more technical and detailed information for planning, building and development projects.

These include:

  • survey approvals online
  • survey and land records
  • client services
  • cadastral infrastructure
  • Aboriginal community surveys
  • geodetic and positioning infrastructure.

Online information that requires specific programs to search graphically and textually is available on the Department of Infrastructure, Planning and Logistics website including:

  • global navigation satellite
  • digital cadastral database
  • continuous operating reference station.

A web based inquiry system is currently being redeveloped so you can search graphically and textually for coordinated survey marks in the NT.

Until this system is completed, if you need information on survey marks contact Survey Services.

Phone: 08 8995 5362

If you are a registered user, you can apply online for Survey Data Allocation and lodgement of survey documents.

To access the online system, registered users can go to Survey Approvals Online and log in.

The Survey and Land Records unit has two main areas of responsibility:

  • statutory survey services
  • the management and storage of land records.

Statutory survey services

This area is responsible for making sure survey data for land subdivisions meets the legal and statutory requirements and maintains the integrity of the land title system.

Survey and Land Records carries out the following functions:

  • provide advice to surveyors, the general public, associated professionals and government agencies on surveying, survey requirements and subdivision processes
  • access survey data for compliance with statutory requirements prior to approval by the Surveyor-General. Read the Licensed Surveyors Act 1983.
  • carry out audits on survey data and provide feedback to licensed surveyors
  • allocate parcel numbers and survey data for new land subdivisions.

Survey data that requires approval by the Surveyor-General must be formally submitted to Survey Approvals Online along with the relevant payment for survey lodgement.
