HMAS Tasmania following its transfer to the Royal Australian Navy.
It recommissioned into the RAN as HMAS Tasmania at Devonport, England on 27 January 1920 under the command of Lieutenant Commander H O Joyce RN. It sailed for Australia on 20 February in company with Success, Swordsman and Tattoo, and arrived in Sydney on 29 April via Gibraltar, Malta, Port Said, Suez, Aden, Mumbai, Colombo, Singapore, Surabaya and Thursday Island.
Postwar cuts to defence spending saw several RAN vessels decommissioned and Tasmania was one of those affected. It decommissioned at Sydney on 6 October 1921 and was placed in reserve. It recommissioned in September 1922 and, except for a visit to New Guinea in June-July 1924, served the remainder of its seagoing career in eastern and southern Australian waters. It decommissioned again on 9 January 1928 and was placed in reserve. Tasmania was eventually sold for breaking up on 4 June 1937.
