Acacia Gardens is located 40 kilometres west of the Sydney central business district, in the local government area of the City of Blacktown. Acacia Gardens is part of the Greater Western Sydney region and loosely considered to be part of the southern end of the Hills District.
Acacia Gardens was formerly a part of Quakers Hill. The name was chosen to reflect the rural quality of the suburb, with acacia trees being prevalent in the area. Many of the streets in the suburb are named after flowers. It was formally recognised as a suburb in 1996.
Acacia Gardens, being a relatively small suburb, only has one primary school, Quakers Hill East Primary School in the area. Nearby, there are two other public primary schools Barnier and Hambledon. High schools in nearby suburbs include Quakers Hill High, Wyndham and Glenwood High. There is also nearby Catholic primary schools Mary Immaculate and Blessed John XXIII Primary. Nearby Catholic high schools include Terra Sancta College and St Mark’s Catholic College.
