Green Hill Fort

Green Hill Fort is a heritage-listed late 19th-century coastal defence fort on Green Hill, the highest point of Thursday Island in the Torres Strait, Queensland. Built between 1891 and 1893 to defend the Torres Strait and northern Australia, it retains gun emplacements, underground tunnels and magazines. Now home to the Torres Strait Historical Museum, it offers panoramic views and insight into the region's military and maritime history.

Visitors can explore the well-preserved fort complex on top of Green Hill, including original 6-inch breech-loading gun emplacements, underground tunnels, magazines and defensive walls. The site houses the Torres Strait Historical Museum with displays on military history, pearling and Island culture. The hilltop provides 360-degree views over Thursday Island, Horn Island and the Torres Strait. Access is via a steep sealed road and walking paths with interpretive signage.

Constructed 1891-1893 as part of Australia's coastal defence system following concerns over security of the Torres Strait shipping route. Built to house three 6-inch breech-loading guns to protect the strategic waterway. Garrisoned until 1920s and later used during World War II. Listed on the Queensland Heritage Register as an important example of 19th-century military fortification in northern Australia.

Represents the strategic importance of Torres Strait to Australia and preserves military and maritime heritage of the region. The Torres Strait Historical Museum within the fort showcases Torres Strait Islander culture, pearling industry and local community history.
