Engadine is located 33 kilometers from the Sydney central business district and is under the local area government of the Sutherland Shire.
In 1879 the area was reserved as a national park but the following year Charles McAlister was able to purchase land here which became known as McAlister’s Estate. After returning from a holiday in Switzerland the family renamed their estate Engadine after the Engadin Valley. The wildflowers and the valley here reminded them of the valleys and hills in Engadin.
Originally opened for grazing land, the area soon became a popular day trip and camping spot from the inner suburbs. It remained relatively isolated till the railway station was built in 1920. Many ex-soldiers settled here after World War One with many Streets in the area reflecting the military past Anzac, Vilers Brett, and Amiens.The Post Office opened in 1927 followed by the school in 1932. In the 1960′s the land was opened up for private housing.
