The Geological Survey of NSW (GSNSW) was founded in 1875 and is the state’s oldest continually operating
government agency. GSNSW collects and manages geological, geophysical and geospatial data to inform the government, resource industry and the community about the state's geology, and renewable, mineral, coal and petroleum resources. It 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.
