Deal Island has the highest
lighthouse in the
Southern Hemisphere, standing
above sea level and was sometimes visible at night from Wilson's Promontory, away. The lighthouse was built in 1848 and deactivated in 1992. While active, the height caused problems with visibility in
low cloud conditions. Management and conservation is under the control of the
Tasmania Parks and Wildlife Service. On 26 April 1943, during
World War II, a
Royal Australian Air Force A25 Airspeed Oxford aircraft crashed, killing all four crewmen. The aircraft wreck and their graves are about apart at the bottom of the cliff. The bodies have since been disinterred and buried at Springvale, Victoria. Eyewitness accounts say the plane flew low over a ship which was actually a wreck, and then failed to regain enough height before hitting the cliff. ==See also==
