With 134 skyscrapers over 90m, Sydney has the largest skyline in Australia.
Height restrictions were lifted in the 1950s and the AMP Building at Circular Quay became Australia's tallest building several years later. The late 1980s and early to mid-1990s saw a skyscraper boom in Sydney, but height restrictions limited future buildings to the height of 235 metres, in part due to the close proximity of Sydney Airport.
