Green Hill Fort, Thursday Island

Green Hill Fort is a heritage-listed fortification at Chester Street, Thursday Island in the Torres Strait, Queensland, Australia. The fort is important in Australian military history as a strategic coastal defence installation in the period of transition from British to Australian responsibility for defence. The 1885 confrontation between Britain and Russia, which almost resulted in open conflict, galvanised the Australian colonies to jointly fund construction of the fortifications, and these represent an important and uncommon instance of pre-Federation Colonial cooperation on defence in the "national" interest. The fort was added to the Australian Commonwealth Heritage List on 28 May 2008. ()
