Explosives Magazine and Detonator Store is a heritage-listed former gunpowder magazine at Magazine Street, Stratford, Cairns, Cairns Region, Queensland, Australia. It was built in 1901 by JC Thomson. It was added to the Queensland Heritage Register on 21 October 1992. History The powder magazine and detonator store at Stratford, near Cairns, were constructed in 1901 for Queensland Government's Marine Department, which was the government authority responsible for storing the large quantity of explosives, both government and privately owned, being shipped into the port of Cairns at the turn of the century. From 1860 to 1963, control of all explosives/gunpowder imported into Queensland was the province of the Harbour Master's Department (1860–62), the Department of Ports & Harbours (1862–93), the Marine Department (1894-1928), and the Department of Harbours and Marine (1929–63). In 1964, responsibility was shifted to the Queensland Department of Health. Under The Navigation Act of 1876, the master of any ship entering a Queensland port with gunpowder to be unloaded, had to ensure that it was placed in a government magazine. The Ports & Harbours Department therefore was responsible for the provision of magazines and for the safe storage of explosives at Queensland ports of entry. The Act further regulated the conveyance and storage of gunpowder in any place in Queensland, not just in the ports. From the late 1860s, government magazines were being erected at the principal ports and goldfields of Queensland. On the goldfields, magazines were administered by the Mines Department; control of magazines other than in ports was not vested in the Marine Department until 1907, under the provisions of the Explosives Act of 1906. These magazines were constructed of stone, brick, timber or iron, largely dependent on the local availability of materials. At some ports, floating magazines were utilised. By 1900, magazines under the control of the Marine Department were situated at Brisbane, Maryborough, Bundaberg, Gladstone, Rockhampton, Bowen, Townsville, Cairns, Cooktown and Normanton. None of these appears to have been of concrete construction. The magazine at Cairns was a barge, , anchored off the east side of Trinity Inlet since October 1884, and was the reason for the naming of Magazine Creek on that shore. In mid-1900, the Cairns magazine was receiving explosives at the rate of 2,716 cases per annum, the amount was increasing rapidly, and traders were clamouring for storage space. Explosives were imported to Cairns by Brisbane-based merchants such as Brabant &
