• St Clair is a suburb of Sydney, in the state of New South Wales, Australia. It is 39 kilometres west of the Sydney central businessdistrict, in the local government area of the City of Penrith and ispart of the Greater Western Sydneyregion. St Clair is within view of the Blue Mountains. History St Clair takes its name from a residential housing development established in 1970. The current StClair Post Office opened on 17 March 1981   The area was formerly part of a larger area named South Creek. It was later, unofficially, known as South St Marys, with the southern section being named Erskine Park. The original site of St Clair was once part of Chatsworth Nursery, a branch of Darling Nursery, which had beenestablished in 1827 during the reign of King George IV. The owner Thomas Shepherd developed an irrigation system utilizing waterfrom Eastern Creek and a large portion of the area was covered withCamelia orchards. The nursery, known for its camellias, was moved to Colyton and existed until the end of the 19th century. The area remained largely rural until a new housing development in the 1970s. The name "St Clair" has no historical links with the area. It was the name given to a residential housing development established in 1970 by the Latex Finance Company, a subsidiary of the Cambridge Finance Company which went bankrupt in the year 1976. The Land Commission of New South Wales acquired the land after a bankruptcy declaration and extended the area to create a large suburb. TheGeographical Names Board of New South Wales eventually made the decision in late 1981 to divide the area into two separate suburbs named St Clair and Erskine Park, rather than call the whole area Erskine Park as many people had desired. Itspopulation has soared since 1981 and is now a well established suburb with modern facilities with close access to the M4 Motorway and shopping centre. Location The suburb is bordered by Erskine Park Road to the east, the M4 Motorway on the north and MamreRoad along its western boundary. The suburb to the south and east of St Clair is Erskine Park. Considerable parklands provide open space for recreational activities and St Clair is renowned for having a family oriented atmosphere. Next to St Clair is Erskine Park but once called Fox Dale, which is located on the eastern and southern sidesof Erskine Park Road. Fox Dale is not as big as St Clair in housingand population, but a massive new industrial area to the south encompassing developments on Lenore Lane and James Erskine
    Drive is partially developed and bringing new opportunities to the area. The new development is expected to bridge Old Wallgrove Rd with Lenore Lane and Archibold Road in the future. This will create a freight corridor connecting the area's three main industrial areas at Minchinbury, Erskine Park and Wonderland, along with the two mines in the area, encouraging heavy vehicles down non-suburban back roads, freeing up the existing roads for car traffic, and substantially reducing travel time from the current 45 minutes in heavy traffic to 10 minutes Schools The suburb has one public high school which is located on Endeavour Avenue, named St Clair High School. Some St Clair residents are zoned to go to the nearby Erskine Park High School. Private high schools near St Clair include Emmaus Catholic College and Mamre Anglican School. Primary schools in St Clair include St Clair Public School, Banks Drive Public School, Blackwell Public School, Clairgate Public School, Trinity and Holy Spirit Catholic School. A fire occurred at St Clair High School in the early morning hours of 29 June 2014.[4] Fire and Rescue NSW reported later that morning that the fire was extinguished by 0545, but that 80% of a two-storey building was destroyed. No injuries were reported.
