Indigenous Meaning

The original inhabitants of the NSROC Region were the Birrabirragal, Boregal, Cammeraygal, Darkingung, Dharug, Gonualgal, Kuringgai and Wallumedegal Aboriginal people.


European settlement dates from 1792 when the first land grants were made. Land was used mainly for farming and timber-getting. Some growth took place in the 1820s and 1830s, due to improved access. Growth took place in the 1880s and 1890s, spurred by the opening of railway lines, with villages growing up around the railway stations and many market gardens and orchards established. Expansion took place in the 1920s and 1930s, aided by the opening of the Sydney Harbour Bridge. The most significant development occurred during the post-war years, with rapid growth during the 1950s and 1960s. The population of the Region increased gradually from the 1990s, rising from about 466,000 in 1991 to about 594,000 in 2016. Most of the growth from the 1990s has been in Hornsby Shire, the City of Ryde, Willoughby City and the North Sydney Council area, with considerable growth from 2006 in the Ku-ring-gai Council area. Much of the recent growth has been from urban consolidation, particularly high and medium density housing development in mixed use areas, with some redevelopment of former industrial sites.
