HMAS Encounter was a Challenger-class second-class protected cruiser built by HM Dockyard Devonport, completed at the end of 1905. The vessel measured approximately 376 feet 1.75 inches (114.65 meters) overall in length, with a beam of 56 feet 2.125 inches (17.12 meters) and a draught of 21.25 feet (6.48 meters). Displacing around 5,880 tons, Encounter was powered by a Keyham 4-cylinder triple expansion steam engine, delivering 12,500 horsepower to two propeller shafts, enabling her to reach speeds just over 21 knots (39 km/h). Her cruising range was 5,436 nautical miles (10,067 km) at 10 knots, powered by 1,314 tons of coal. She was among the first Royal Navy ships equipped with water-tube Dürr boilers. Her armament initially included eleven BL 6-inch Mk VII naval guns, nine QF 12-pounder 12 cwt guns, six 3-pounder guns, three machine guns, and two 18-inch torpedo tubes. By the 1920s, her armament was reduced, with modifications including the addition of a 12-pounder field gun and replacement of smaller guns with Maxim and Lewis guns. Launched on 18 June 1902 and commissioned into the Royal Navy on 21 November 1905, Encounter served initially with the RN Australia Squadron until 1912, after which she was transferred to the Royal Australian Navy. During her service in World War I, she became notable as the first RAN ship to fire in anger, bombarding Toma Ridge during the occupation of German New Guinea in 1914. She also participated in operations in the New Guinea, Fiji-Samoa, and Malaya regions, capturing vessels and supporting landings, including the landing at Madang. Encounter underwent repairs and refits during her wartime service, including a significant refit in Sydney in 1917-1918. She was involved in convoy duties, rescue operations, and patrols, earning the battle honour "Rabaul 1914." She was also temporarily renamed HMAS Penguin and served as a depot ship before being decommissioned in 1929. Ultimately, she was scuttled off Bondi Beach in 1932 at a depth of approximately 74 meters, where she remains a popular dive site. Her service marked a significant chapter in Australia's naval history during the early 20th century.
