Sylvania is a suburb in southern Sydney, New South Wales, Australia, south of the Sydney central business district in the Sutherland Shire. It is well known for its large waterfront properties and restaurants. Sylvania is mostly residential but also contains areas of native bushland and some commercial developments on the Princes Highway and Port Hacking Road. Sylvania Heights is a locality in the western part of the suburb. Sylvania Waters and Kangaroo Point share the same postcode (2224). History The traditional owners of Sylvania are the Dharawal Aboriginal people and their archaeological heritage is evident in a number of registered middens, burial and art sites in rock shelters on the Georges River. After European settlement, this land was acquired by John Connell Laycock as a Crown grant. Thomas Holt (after whom Holt Road is named), a prominent landowner, financier and politician, acquired it a few years later as part of the Holt-Sutherland Estate, some . The name of the suburb relates to its original wooded vegetation. The word "Sylvania" comes from the Latin word sylvan or sylva which means "forest land". The native vegetation of the suburb is now fast disappearing, as a result of increased development. Thomas Holt built Sutherland House on the foreshore of Gwawley Bay in 1818, on the eastern side of Sylvania. He established the Sutherland Estate Company in 1881 and a village grew here, with a post office opening in 1883. The school opened in 1884 but closed in 1891 and was not reopened until 1925. Sylvania Heights Public School opened in 1955. 'Sutherland House' no longer stands (only its gate posts survive), but there are a number of heritage-listed buildings in the suburb. They include the original St Mark's timber church (now a Sylvania Public School class room) timber residence in Evelyn Street associated with the Holt Estate; 'Glenn Robin', built by William Glenn Wade on land he acquired in 1949 and completed in 1954; and 'Green Gables' built by Sidney and Clarisse Bayer between 1946 and 1952 on Kangaroo Point.* In 1913, the area bounded by Florida Street, Harrow Street, Mowbray Street and Illawarra Road (now the Princes Highway) was known as the Swastika Estate. Much of the land of Sylvania Waters was 'reclaimed' from Gwawley Bay, effectively destroying the highly integrated mangrove flora of the bay. Sylvania Waters Estate was developed by L.J.Hooker in the 1960s; land offered had water frontages with
