The "SS Koopa", often referred to as the "Queen of Moreton Bay", was the best known and most loved ship among the many steamers that plied the waters of Moreton Bay from the 1880s until 1953. The "SS Koopa" also serviced Woody Point and Redcliffe from Brisbane. For thirty-one years Koopa did the Brisbane-Redcliffe-Bribie run carrying thousands of holiday makers. In 1942 Koopa was requisitioned by the Royal Australian Navy and commissioned on 14 September. The Navy made many alterations to the ship which served as a supply ship in New Guinea waters during the remainder of World War II. It was the tender, mother-ship and repair facility for a group of sixteen Fairmile patrol boats. Koopa returned to Brisbane in July 1945 and underwent a major naval refit. After naval service, the ship was returned to the Brisbane Tug and Steamship Company in February 1947. Trips were resumed to Redcliffe and Bribie on Sundays, Tuesdays, Thursdays and Saturday afternoons. In 1952 Koopa was bought by the Moreton Bay Development Company which continued the usual run until her final trip in May 1953. On 3 October 1960 two tugs took Koopa from the Stanley Wharf at South Brisbane to Boggy Creek, Myrtletown. A week later it was moved and placed opposite Bulwer Island where dismantling proceeded.
