The AS350BA Squirrel helicopters are for aircrew training, utility duties and support of air-capable ships within the RAN Fleet. The Squadron’s primary role is rotary wing training for pilots, observer and aircrew. The Squadron's duties also include limited fleet support in range clearances, and flight deck procedural training, plus some embarked support on major warships. AS 350BAs operated from all helicopter-capable RAN ships during the 1991 Gulf War. They were fitted with updated avionics and a door-mounted machine gun. Their deployment included shipping surveillance, top cover for helicopter boardings, light logistics support and mine searches.

They have also assisted in bushfire control efforts, being tasked with providing logistic support to firefighters on the ground, fire spotting and transport for supervisors.
