4 Squadron Australian Flying Corps began it's operational service with the Sopwith Camel. The Sopwith Camels were in the standard factory finish of PC10 upper surfaces and CDL lower surfaces. The plywood area were covered clear and the cowl area was either polished aluminium or painted in Battleship Grey depending on the manufacturer of the aircraft. The squadron insignia matched 2 Sqn AFC's insignia with the white boomerang being aft of the roundal on the fuselage. Unlike the 2 Sqn SE5.a's though the boomerang marking on the Sopwith Camels was mimiced on the upper surface of the turtledeck.
The Sopwith Camel depicted above was a Sopwith Camel which was ferried into squadron service by Lieutenant George Jones on the 25th of February 1918. The aircraft was to survive three months in the squadron with C Flight. The New Zealander Lieutenant Herbert G. Watson was to score two victories with the aircraft, sending an Albatros DV out of control on the 19th of April 1918, and downing a Pfalz DIII on the 11th of May 1918. .
