As the Twin Comanche aircraft approached a heading consistent with a crosswind leg of the traffic pattern the pilot in command and two of the passengers sighted the Cessna aircraft very close on their starboard side. The pilot in command took immediate action in an attempt to avoid the Cessna but, before this action became effective, the starboard propeller of the Twin Comanche passed through the elevator, tailcone, rudder and lower rear fuselage of that aircraft. The Twin Comanche passed beneath the Cessna, crossing from left to right. At 1326:50 hours EST the pilot in command of the Twin Comanche notified Bankstown Tower that his aircraft had collided with another aircraft.
