*Observation deck (Eureka Skydeck 88)*
....Eureka Skydeck 88 occupies the entire 88th floor of the Eureka Tower and is the highest public vantage point in a building in the Southern Hemisphere at 285 m (935 ft). It opened to the public on 15 May 2007.
....The Skydeck features thirty viewfinders that help visitors to pinpoint numerous significant landmarks around all parts of Melbourne, along with several free binoculars. There is a small outside area called 'The Terrace' which is closed in high winds.
.... There is also a glass cube called 'The Edge', which extends itself from the building to hang over the edge of the tower and add to the viewing experience.
** 'The Edge' projects 3 m (10 ft) out with visitors inside, suspended almost 300 m (984 ft) above the ground. When you enter, the glass is opaque as the cube moves slowly out. Once fully extended over the edge, the glass becomes clear.
