Sky high

Sydney boasts a tower as do most notable cities of the world. The Sydney Centrepoint Tower is a Mecca for tourists and locals alike and a visit to the city would not be considered complete unless the tower was included.
If you look carefully you will see an outside viewing deck on the left hand side of the photo. The tower has the standard 360 degree surround platform and of course the usual restaurant and for an extra fee the outside deck can be accessed.

Not for the fainthearted I can assure you.
