Operational history
On completion, Melbourne sailed from Portsmouth for Australia, arriving in Fremantle on 10 March 1913. Until August 1914, the cruiser was primarily involved in training cruises and port visits around Australia. During August and September, the cruiser operated with other Australian warships in the Pacific as a counter to the German East Asia Squadron, and was involved in the capture of several German colonies. Melbourne returned to Sydney on 20 September, and on 1 November joined the escort of the convoy transporting the Australian and New Zealand Army Corps to Egypt. The cruiser left the convoy while in the Indian Ocean, and headed for Gibraltar, where she was then instructed to head for the Azores in search of the German cruiser SMS Karlsruhe. By the time she reached the Azores on 12 December, Melbourne had been reassigned to Bermuda as part of the North America and West Indies Station. While on the Station, the cruiser patrolled the western Atlantic from Canada to Brazil. In August 1916, she sailed for Devonport in England, where she spent a month before joining the 2nd Light Cruiser Squadron of the British Grand Fleet, stationed at Scapa Flow. From January until June 1917, Melbourne was docked at Birkenhead for major repairs to her propulsion system. The cruiser was fitted with an aeroplane platform in November 1917. On 1 June 1918, Melbourne launched her aircraft after sighting German aircraft over Heligoland Bight, but the pilot lost his target in the clouds. At the surrender of the German High Seas Fleet, Melbourne was assigned to escort. The cruiser remained with the Grand Fleet until 30 November 1918: during the entire war, Melbourne was not involved in any sea battles. Initially, the cruiser was not awarded any battle honours, but a reorganisation of the RAN honours system published in 2010 retroactively awarded the honours "Rabaul 1914" and "North Sea 1916–18" to the ship. in 1918. Melbourne was the only ship of the RAN to be painted in dazzle camouflage during World War I. Melbourne stayed in Portsmouth until 7 March 1919, then sailed for Sydney via Suez, Singapore, and Darwin. The ship was paid off into reserve on 5 August 1919 until 14 April 1920, when she was recommissioned. In 1922, the ship rescued personnel from the sailing vessel Helen B. Sterling, which had been disabled in the Tasman Sea by a gale. Also in 1922, the ship was assigned as Flagship of the Australian Squadron. She was returned to reserve on 29 September 1924; most of the four years in service had been spent in Australian waters, with cruises to New Zealand and the Pacific Islands. The cruiser was recommissioned on 8 October 1925, and left Sydney for England on 23 November. During 1926, the ship was assigned to the Mediterranean Fleet on exchange, with the British cruiser sent to operate with the RAN. Melbourne returned in August 1926, and resumed duties as Flagship.
Fate
On 9 February 1928, Melbourne commenced her last voyage to England, where she arrived on 12 April. Melbourne was decommissioned for the final time on 23 April, with her ship's company assigned to the new heavy cruiser. The ship was sold to the Alloa Shipbreaking Company on 8 December for 25,000 pounds. The cruiser was transported to Birkenhead, and was broken up over the course of 1929.
