English: Sydney Tower is Sydney's tallest structure, it is also the second tallest observation tower in the Southern Hemisphere, after Auckland's Sky Tower, though Sydney Tower Eye's main observation deck is almost 50 m (164 ft) higher than that of Auckland's Sky Tower. The name Sydney Tower has become common in daily usage, however the tower is also known as the Sydney Tower Eye, AMP Tower, Westfield Centrepoint Tower, Centrepoint Tower or just Centrepoint. The Sydney Tower is a member of the World Federation of Great Towers.

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, and sits upon the newly refurbished Westfield Sydney (formerly centrepoint arcade). 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.

While the shopping centre at the base of the tower is run by the Westfield 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 and Oztrek [Wikipedia.org]
