HMAS Psyche (formerly HMS Psyche) was a protected cruiser built for the Royal Navy at the end of the 19th century. Initially operating on the North America and West Indies Station, the cruiser was transferred to the Australian Squadron in 1903, and remained there until the Royal Australian Navy (RAN) took over responsibility in 1913. After a stint in New Zealand waters and involvement in the Occupation of German Samoa, Psyche was paid off in 1915.

At the recommendation of the Australian government, the ship was commissioned into the RAN in 1915, and assigned to patrol the coast of Burma, in response to the threat of a German-instigated uprising. Psyche operated in the Bay of Bengal and around Sumatra until 1916, when she was docked at Hong Kong for refit. During this, personnel from the ship were used to commission and man the river gunboat . After the refit's conclusion, Psyche patrolled in Chinese waters, before returning to the Bay of Bengal. Psyche returned to Sydney and was paid off in October 1917, but recommissioned a month later for patrols in Australia's northern waters. She was decommissioned for the final time in early 1918. The ship was sold for use as a timber lighter in 1922, and sank in 1940 at Salamander Bay, New South Wales following a storm.

Design and construction

Psyche was a third-class protected cruiser of the nine-ship Pelorus- or P-class. She had a displacement of 2,135 tons, was long overall and long between perpendiculars, had a beam of , and a draught of . Psyche was capable of reaching , although she normally operated at the more economical speedo of . The ship's company initially stood at 220, but this was later reduced to 188; 12 officers, and 176 sailors. Commander Edmund Moore C. Cooper-Key replaced Pelly in command in June 1901. She was at Bermuda in March 1902, visited Colón, Panama in early May, and Havana in late May 1902; and was in Nicaragua in July 1902, when the government captured revolutionists from an attempted coup. The following month she left Bermuda homeward bound, returning to Devonport on 20 August, to pay off on 5 September when she was placed in the D division of the dockyard reserve.

In December 1903, she was transferred to the Royal Navy's Australian Squadron, where she served until October 1913, when the Australia Station was handed to the control of the fledgling RAN. In 1914, Psyche formed part of the escort for the New Zealand Force which occupied German Samoa (now Samoa). Psyche also escorted troop ships heading from New Zealand to the Middle East. For Psyche, 10- to 12-day patrols along the Burmese coast were the norm, interspersed with crew training duties. All seven were found guilty of disobeying orders, and were punished with prison sentences between 12 and 14 months, plus dismissal from the RAN. During April, further patrols of the Bay of Bengal were made, before Psyche sailed to Hong Kong for inspection and refit. Psyche was reactivated on 20 November 1917 for service along Australia's north-east coast, but after uneventful patrols, she was decommissioned for the final time on 26 March 1918. The wreck was used by RAN clearance divers for training between 1950 and 1973, and was later broken up during an underwater demolitions exercise.
