Standing at 305m (1001ft) high, Sydney Tower is the tallest building in Sydney. Located in the Central Business District in the heart of the city, visitors can experience amazing views across Sydney Harbour from the Observation Deck. The tower, which was completed in 1981, also has a revolving restaurant which slowly rotates through 360° views. Visitors can also experience the OzTrek attraction, a simulated journey showcasing Austalia's culture, history and geography. There are three main sections of the tower open to public access. One is the observation deck at 250 metres above ground level with a fully-enclosed viewing platform featuring 360 degree views of the city and surrounds. This floor also features a small gift shop, a readout displaying data on the conditions of the tower (wind speed, direction and sway amplitude). The Skywalk platform at 260 metres above ground level has an open-air viewing platform only accessible as part of planned and booked tours. Finally, there are two revolving restaurants, one à la carte and one buffet.
