Shire Christian School is an independent non-denominational Christian co-educational early learning, primary and secondary day school, located in Barden Ridge, a suburb in the Sutherland Shire area of Sydney, New South Wales, Australia. The school was founded as Sutherland Shire Christian School in 1977 by a group of local parents who felt a calling to provide their children with an environment in which to gain an education taught from a Christian perspective.
