<P> 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 . The list includes only habitable buildings, as opposed to structures such as observation towers, radio masts, transmission towers and chimneys . </P> <P> 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 . </P> <Table> <Tr> <Th> Rank </Th> <Th> Name </Th> <Th> Image </Th> <Th> Location </Th> <Th_colspan="2"> Height: m (ft) </Th> <Th> Floors </Th> <Th> Year </Th> <Th> Notes </Th> <Th> Reference </Th> </Tr> <Tr> <Th> </Th> <Th> ES </Th> </Tr> <Tr> <Td> </Td> <Td> Q1 </Td> <Td> </Td> <Td> Gold Coast </Td> <Td> 322.5 (1,058) </Td> <Td> 275 (902) </Td> <Td> 78 </Td> <Td> 2005 </Td> <Td> Tallest building on the Gold Coast and Australia since 2005 .
