Condell Park was named after Ousley Condell, an engineer who arrived on 8 May 1829 on the barque Swiftsure with 13 other settlers. He applied for a position in the public service and was granted four 50-acre (200,000 m²) adjoining lots in 1830 that he called Condell Park.

Black Charlie's Hill, located in Simmat Avenue Condell Park, was named after a local identity whose nickname was 'Black Charlie'. His real name is said to have been Charles Luzon or Charlie Lopez, a man of Aboriginal ancestry. He lived near Edgar Street, South Yagoona and like others in the area, during the early 1900s, grew vegetables that he carried off to the market by horse and cart. His home was constructed of corrugated iron. Black Charlie was said to fire a single shot each evening promptly at 9pm but the reason was never disclosed. Some suggested he was hunting rabbits, others to warn of the approach of aircraft.

The Bankstown Bunker was an exact replica of the underground Ops rooms of wartime England, which directed Britain's air defence fighter plane attacks on the invading German Luftwaffe. It had all the attenuated fixtures necessary to run a top secret operational defence base. The bunker was equipped with its own code room, plotting rooms, two escape tunnels and a radio transmitter room. In the centre of the bunker was a large room of about two-stories in height. This was the main Ops room and control centre for all RAAF Missions in the Pacific area. The room also had a large map of the South West Pacific theater of World War II.
