Formerly, the tallest structure in Australia was the Omega Navigational Mast Woodside in Woodside, Victoria. The Omega Tower was demolished by Liberty Industrial on behalf of the Department of Defence on 22 April 2015 following the death of a young base jumper in 2014 after his parachute failed to open.
This is a list of the tallest structures in Australia. This list contains guyed masts, towers, skyscrapers and chimneys with a height of 200 metres or more.
