The cruiser HMAS SYDNEY, (CAPT J. S. Dumaresq, RAN), in company with HMS DUBLIN and four destroyers, was attacked by the German zeppelin L43 in the North Sea. CAPT Dumaresq reported in the ship’s Proceedings: ‘The gunnery officers of SYDNEY and DUBLIN made very good shooting with the HA guns, keeping the airship at such a height as to make her bomb dropping inaccurate’. SYDNEY was the first ship of the RAN to be subjected to an air attack.
