Chester Hill is mostly in the City of Canterbury-Bankstown, with a minor part in the northeast in the Cumberland Council local government area.

Part of Western Sydney, Chester Hill shares the postcode of 2162 with the neighbouring suburb of Sefton, to the east.

[citation needed] A local resident, Miss H. A. McMillan first suggested that the new railway station should be called Hillcrest (after an estate near Regent's Park), but many objections were raised and the name was discarded.

[3][4] A significant tract of land between Priam and Hector Streets had been occupied by the Royal Australian Air Force (RAAF) from the 1960s.

[citation needed] This area was used for accommodation and mess facilities for the nearby 2 Stores Depot (Regents Park) and the Ground Equipment Maintenance Squadron (Villawood).

[1] Chester Hill is officially the gun capital of Sydney, with one registered firearm for every 3.8 residents according to 2015 police data.
