J & G Thomson in Govan, Glasgow built the iron-hulled ship, City of Adelaide for the Australasian Steam Navigation Company. 

She was launched on 22 December 1863 and completed in 1864. Her registered length was 246.0 ft., her beam was 28.3 ft., and her depth was 16.6 ft. Thomson's also built her marine steam engine, which had two cylinders and was rated at 200 horsepower.
Her owners registered City of Adelaide at Sydney. Her United Kingdom official number was 49261 and her code letters were WCHB.
City of Adelaide ran regular passenger services between several destinations including Melbourne, Sydney, Honolulu and San Francisco.
In 1871 the ship was refitted, and her masts were reduced from three to two to increase her passenger accommodation. She served for a further 14 years before being retired in 1885. After the merger of the Australasian Steam Navigation Company with the Queensland Steam Shipping Company, in 1887, City of Adelaide continued in service with the successor company Australasian United Steam Navigation Company.
In 1890 WA Ritchie of Sydney bought her and had her converted to a four-masted jackass barque by removing her boilers and engines and adding two new masts. In 1895 GJ Robertson of Sydney bought her. In 1902 Howard Smith Company of Townsville bought her and turned her into a coal hulk.
In 1912 the ship caught fire and burnt for some days before flames were extinguished. In 1915, by George Butler, the son of the first European resident of Magnetic Island, bought her burnt hulk. He had the hull stripped, and an attempt was made to float the ship to Magnetic Island’s Picnic Bay, where she would be scuttled as a breakwater for a jetty. However, as the ship was being towed from Townsville to Picnic Bay she ran aground off Magnetic Island's Cockle Bay.
In World War II the Royal Australian Air Force (RAAF) used the wreck for target practice for bomber crews from the nearby Garbutt Airfield. On 22 October 1942, six RAAF Bristol Beaufort bombers of 100 Squadron made a coordinated mock torpedo attack on Townsville Harbor, followed by a coordinated practice bombing of the wreck. The mock attack on Townsville Harbor was a success, after which the six bombers climbed to about 1,000 feet (300 m) and flew in a vee formation towards Cockle Bay.
Several of the aircraft dived at the wreck in a bombing run, during which one of the aircraft appeared to strike one of the masts of the sunken ship, before crashing into the shallow sea about 700 metres (770 yd) from the ship. The plane's fuselage disintegrated on impact, instantly killing three RAAF officers and a United States Navy officer aboard the bomber.
The wreck is about 300 metres (330 yd) off the shore of Cockle Bay. On 24 December 1971 Cyclone Althea struck the coast of northern Queensland near Magnetic Island, causing the part of the wreck’s iron hull to collapse. However, the wreck remains an artificial island, hosting a diversity of plant and animal life.
