The Torres Strait, located in Queensland, Australia, is home to several historical forts that showcase the region's strategic significance in British and Australian colonial trade and defense. One notable example is Green Hill Fort on Thursday Island, built between 1891 and 1893 as part of Australia's defense system to protect against sea invasions during the 1855 war and World War II. The fort features five rooms with 600-millimeter-thick concrete walls for ammunition storage, alongside a guardhouse, cooling plant machine room, and powder room added in 1912, with well-preserved gun emplacements and underground bunkers for visitors to explore.
The Torres Strait Museum and Historical Society Association maintains and displays various themed exhibits within the fort's rooms, including the Wanetta Collection, a compilation of gifts, souvenirs, and collectables. The site also features a defense display in the Powder Magazine, the Lighthouse Room showcasing a second-order lens from Booby Island Lighthouse, and a pearl-shelling and shipping collection in the Shell Store. Visitors have the opportunity to delve into the region's cultural and military history by exploring these well-preserved fortifications and engaging with the themed exhibits.
