HMAS Tasmania (H25) was an Admiralty S class destroyer of the Royal Australian Navy (RAN).

Built for the Royal Navy during World War I, the ship was not completed until 1919, and spent a year commissioned but not operational in British service before being transferred to the RAN at the start of 1920.

[2] The destroyer's economical speed of 13 knots (24 km/h; 15 mph) gave her a range of 2,589 nautical miles (4,795 km; 2,979 mi).

[2] These were supplemented by a 2-pounder pom-pom, two 9.5-inch howitzer bomb throwers, five .303 inch machine guns (a mix of Lewis and Maxim guns), two twin 21-inch torpedo tube sets, two depth charge throwers, and two depth charge chutes.

[3] Tasmania and three of her sister ships sailed for Australia on 20 February, visiting ports in the Mediterranean, India, Singapore, and the Netherlands East Indies before reaching Sydney on 29 April.
