Each year an event called the "Tower Run Up" has runners scale the 1312 steps (1504 total) to the top. They start at the podium level (30m up) and run 94 flights of stairs with 13 steps each. Record is 6 minutes, 52 seconds set in 1998.

The Sydney Tower Skywalk platform at 268 metres above ground level has an open-air viewing platform only accessible as part of planned and booked tours.

There are two revolving restaurants, one à la carte and one buffet.

Because it is visible from many parts of the city, Sydney Tower has been used to highlight city events, particularly the 2000 Sydney Olympics, when wire figures of Olympic athletes were installed on it.
