Union action meant that no tugs arrived to pull HMAS Sydney out of Fremantle harbour on her departure. In response, the ship initiated an action known as Operation PINWHEEL. The Sea furies of 805 and 808 Squadrons simply started the engines of the aircraft sitting on Sydney’s flightdeck to pull herself clear. Sydney had arrived in Fremantle on 22/2/1952 on her return from Korea in the middle of industrial unrest on the waterfront.
