Time Out says
First opened to the public in 1981, Sydney Tower provides a panoramic 360-degree view from the Pacific Ocean in the east to the Blue Mountains in the west. And if you manage to get past the five levels of the Westfield Sydney Shopping Centre then the most dangerous part is over. Pass through the metal detector and into one of the three double-decker lifts that ascend above the city skyline. Peer through free through binoculars, have a coffee in the lounge, or simply sit back and absorb the spectacle.
