The Geological Survey of NSW (GSNSW) was founded in 1875 and is the state’s oldest continually operating government agency. It collects, manages and delivers geoscientific data to support responsible development of NSW resources, including attracting resource industry investment into regional areas, as well as providing advice for land use planning, and natural resource and environmental management.

GSNSW is the authoritative source of up to date knowledge about the geology, geological evolution and mineral and energy resources of NSW, and collaborates with state, national and international government agencies and scientific bodies to share skills and data and promote coherent information exchange.

GSNSW is based at Maitland and has an office at Orange. The W B Clarke Geoscience Centre is located at Londonderry in Western Sydney.

  • Geological mapping

    Teams of field geologists, geophysicists, mineral geoscientists, palaeontologists and geospatial specialists produce a range of maps for various uses, including exploration for mineral, coal, petroleum, water and construction material resources.

  • Mineral systems studies

    We collate data on the distribution and type of mineral occurrences across NSW. Geologists specialising in mineral systems studies use this data to investigate the way mineralisation occurs to help locate future mineral deposits.

  • Geophysical surveys

    We conduct geophysical surveys and archives the data. Open file geophysical survey data from exploration companies are also archived for public access following title relinquishment.

  • Information and online systems

    We manage the storage, quality assurance and accessibility of the department's geoscience information. This includes developing and managing the databases and online systems that deliver the information to the community.

  • Mineral exploration assessment

    We are responsible for monitoring mineral exploration in the state. Exploration reports are assessed to monitor performance against work program licence conditions, and are reported in a form suitable to be included in the DIGS® system.

  • Land use assessment

    We conduct resource assessments to provide advice on geology and mineral resources in NSW to assist government agencies and local government in land use planning and decision making.
