History
The earliest records of human settlement date back to the early 1800s when Dharug Aborigines inhabited the region. Governor Phillip is said to be the first European to have visited the Hills in 1788. The Hills Shire started developing gradually with its new road systems and farming as more Europeans settled here. The first school started in 1840 followed by a general store and a post office. In 1902, the tram from Parramatta to Baulkham Hills was inaugurated and telephone links were established by 1907. The population rose steadily over the years along with infrastructure development of the Hills Shire.

The second proposed a merger of parts of Parramatta, Auburn, The Hills, Hornsby, and Holroyd to form a new council with an area of and support a population of approximately 215,725.
