The Geographical Names Act, 1966, empowers the Board to assign names to places, to investigate and determine the form, spelling, meaning, pronunciation, origin and history of any geographical name and the application of such name with regard to position, extent or otherwise.
A place is described in the Act as "any geographical or topographical feature or any district, division, locality, region, city, town, village, settlement or railway station or any other place within the territories and waters of the State of New South Wales but does not include any road, any local government area, urban area, county or district under the Local Government Act, electoral district or subdivision, or any school". The Act also specifies the procedures for formalising names.
Dual names
In recent years the GNB has been given the power to allocate dual names on equal status, one european, and the other aboriginal.
