Cambridge Gardens is a Sydney suburb located 54 kilometers west of the CBD. It is a fairly recent suburb. It was officially opened in 1981 and was formerly part of the suburb of Cambridge Park.
Prior to white settlement, what is now known as Cambridge Gardens was historical home to the Mulgoa people. The first land given in this locale was in 1831. The lucky recipient was Phillip Parker King, son of the Governor Phillip Gidley King. The land was adjoined to the Werrington estate that belonged to his sister Mary Lethbridge. The estate was run as a large farm until the 1880s, at that time it was subdivided into smaller farms. This area was ten renamed Cambridge Park.
