Towering above the city of Sydney since 1981, when it became the tallest structure in the city, the Sydney Tower reaches a total height of 305 m — great views are available from the 250-m-high viewing level. The tower is Australia's tallest free-standing structure and the second highest observation tower in the Southern Hemisphere after the Sky Tower in Auckland). The trip up to the observation deck includes a short "4D" movie (3D with effects such as smoke and water) before travelling up in the lift. If looking at the city through windows isn't enough, take the Skywalk tour on the top of the tower.

Sydney Tower, also known as the Sydney Tower Eye, Westfield Tower and formerly albeit still commonly as Centrepoint Tower, is an observation and telecommunications tower that is the tallest structure in Sydney, New South Wales, Australia, as well as the second-tallest observation tower in the Southern Hemisphere. Sydney Tower has also previously been known as the AMP Tower.

The tower stands 309 m (1,014 ft) above the Sydney central business district (CBD), located on Market Street, between Pitt and Castlereagh Streets. It is accessible from the Pitt Street Mall, Market Street or Castlereagh Street and sits above the Westfield Sydney (formerly Centrepoint) shopping centre. The tower is open to the public, and is one of the most prominent tourist attractions in the city, being visible from a number of vantage points throughout town and from adjoining suburbs. Auckland's Sky Tower is taller but Sydney Tower's main observation deck is almost 30 m (98 ft) higher than the observation deck on Auckland's Sky Tower.

While the shopping centre at the base of the tower is run by the Scentre Group, the tower itself is occupied by Trippas White Group, which owns and operates Sydney Tower Dining, and Merlin Entertainments, which owns and operates the Sydney Tower Eye observation deck and outside adventure experience known as the SKYWALK.
