If you want a great view of Sydney go to the Sydney Tower located above Westfield shopping mall in the center of Sydney. The tower stands a little over 1000 feet and you get a 360 degree view of Sydney and the harbor.

The tower opened to the public is 1981 with restaurants, a bar and an observation deck on level 4. You can also purchase a ticket to the Skywalk above the observation deck where you can walk outside attached by a cable for safety.  The Skywalk was closed the day we were there.

My only complaint was that because the restaurants and bar are operated by another company so to access those levels you need to go all the way down and back up another elevator.

However, the views are well worth the price.
