The SS Loongana was a notable Bass Strait passenger vessel launched by William Denny & Brothers in Dumbarton on June 2, 1904. Built for the Union Steamship Company of New Zealand, she was constructed at a cost of £87,794 and served primarily on the Melbourne-Launceston route, replacing the earlier Pateena. The ship's design and engineering marked a significant milestone in maritime technology, as she was the first ship registered in the Southern Hemisphere equipped with steam turbine propulsion. Her propulsion system consisted of three 500-horsepower Parsons Marine Steam Turbines, manufactured by the Newcastle-based Parsons Marine Steam Turbine Company. These turbines drove three screws and enabled her to reach a service speed of 18 knots, with a recorded trial speed of 19.75 knots. The vessel's dimensions included a passenger capacity of 246 in first class and 136 in second class, along with a cargo capacity of 661 cubic metres. Crew accommodations numbered around 98 personnel. Her engineering and speed capabilities led to her being considered one of the first ocean-going turbine steamers globally, with her maiden voyage to Melbourne commencing on August 31, 1904 — just days after the RMS Victorian, which also claimed the title. Throughout her service, SS Loongana demonstrated her reliability and speed, notably during the 1912 North Mount Lyell Disaster, where she crossed the strait in 12 hours and 46 minutes at 22 knots, carrying rescue gear from Victorian mines. She continued her operations until March 1935 when she was replaced by the SS Taroona. Subsequently, she was laid up and eventually sold for scrap to Tanaka Kabusiki Kaisya in Osaka. She was towed there by the vessel Kanna in September 1936, with her scrapping finalized by November of that year. The name "Loongana" is derived from an Aboriginal word meaning "to be swift" or "to fly," reflecting her technological advancements and swift service record.
