Chester Hill, a suburb of the Canterbury- Bankstown local government area, is located 25 kilometres west of the Sydney central business district.   Chester Hill shares the postcode of 2162 with the neighbouring suburb of  Sefton.

Originally part of John Thomas Campbell's estate, known as Campbell Hill, it covered 1,000 acres (4.0 km2). Land was used for market gardens and orchards until the opening of the railway line in 1924 when the area developed into residential and light industrial.

A significant tract of land between Priam and Hector Streets had been occupied by the Royal Australian Air Force (RAAF) from the 1960s. This area was used for accommodation and mess facilities for the nearby 2 Stores Depot (Regents Park) and the Ground Equipment Maintenance Squadron (Villawood). These properties were disposed of and subsequently acquired first by the Southern Cross Bible College and then by Salamah (Muslim) College.
