In July 1920, Dumaresq, now Rear Admiral Commanding HM Australian Fleet, organised the loan of two Avro 504L seaplanes from the Australian Flying Corps to the RAN [REF].
From 1935, naval aviation was focused on the RAN's cruiser force: two County-class heavy cruisers and three Town-class light cruisers, each operating a single Supermarine Walrus amphibious aircraft from a deck-mounted catapult [REF].
