The Bribie Island Second World War Fortifications are heritage-listed fortifications at Woorim and Bribie Island North on Bribie Island, Queensland, Australia. They were built from 1939 to 1943 and were added to the Queensland Heritage Register on 20 July 1993
The Bribie Island Fortifications were constructed from 1939 to 1943 as part of the systems of defence of southeast Queensland during the Second World War, and to provide artillery training for Australian soldiers for overseas service. Other fortifications were also apparent throughout Moreton Bay during the war, at Caloundra and on Moreton Island at Cowan Cowan Point and Rous, which together with the existing installations at Fort Lytton, provided a coordinated series of defensive batteries for the region
Bribie Island was a popular holiday destination from the early twentieth century. Steamers from Brisbane docked at the jetty on the southwestern side of the island, and a road led across the island to the settlement of Woorim, the surfing beach of the island. The island supported a small community, and the permanent residents of the eastern side were relocated from their homes when the Australian Army began moving in to the island in 1939
Two six inch guns, surplus from the First World War, were transported across Pumicestone Passage from the mainland to form the Battery at the northern end of Bribie Island (26.8540°S 153.1292°E). The guns were originally installed on cruciform mountings, consisting of two steel members forming a cross upon which the gun was sited, which were found to be inadequate, for after firing the guns the pivot tilted quite dramatically
The Bribie Island Second World War Fortifications are located along the eastern shore of Bribie Island and consist of the remains of three groups; Fort Bribie on north Bribie Island, Skirmish Point Battery to the north of Woorim at south Bribie Island, and the Royal Australian Navy Station No.4 at the north end of Woorim.
These groups are located facing the northwest channel, being the entrance to Moreton Bay from the Coral Sea/Pacific Ocean, and within sight of Moreton Island to the southeast and Caloundra to the north.
Bribie Island is relatively flat and the northern end is affected by shifting dune formations and tidal erosion. As a result, some remaining structures do not have the same position in relation to the shoreline as they had when constructed
