Question: Where is the tallest building in Australia?

List of tallest buildings in Australia



These are lists of the tallest buildings in Australia.
Australia has more skyscrapers per person than any other country in the world with a population greater than five million,[1] and was one of the first countries in the world to play host to the skyscraper boom along with the United States and Canada. Australia's first skyscraper as then defined was Melbourne's now demolished APA Building, completed in 1889, which was among the tallest buildings in the world at the time. The nation's first skyscraper as defined today by the Council on Tall Buildings and Urban Habitat as buildings exceeding 150 metres was the Australia Square Tower in Sydney, completed in 1967.
The vast majority of Australia's buildings which exceed 150 metres in height are located in the eastern states of New South Wales, Queensland and Victoria, with a smaller number in Western Australia. While Australia's other states and territories contain no skyscrapers as defined, they all play host to numerous high-rise buildings.
Tallest buildings

This list includes the tallest completed and topped out buildings in Australia that reach a height of at least 200 metres (656.2 feet), ranked by their official heights as defined by the Council on Tall Buildings and Urban Habitat (CTBUH). An equal sign (=) following a rank indicates the same height between two or more buildings (in such cases, the building with the highest number of floors is listed first). The "Year" column indicates the year of completion.[2] The list includes only habitable buildings, as opposed to structures such as observation towers, radio masts, transmission towers and chimneys.
Official heights (denoted by 'O') are also known as 'architectural heights', as they include spires but exclude communications masts and antennae. This is because spires form an integral part of a building's design while masts and antennae do not, being purely functional. Also included are heights 'excluding spires' (denoted by 'ES'), which as used here include the entire architectural structure save for architectural spires. Whilst this is not a measure used by CTBUH, the concept is nonetheless frequently referred to by skyscraper aficionados.
