I don't know about @jagsfan But Bill and I just did the Pylon Climb. Our bungee jumping and bridge climbing days are behind us. The Pylon climb was awesome, we could look down from the top and watch the bridge climbers, along with fabulous photos of the harbor and skyline. And the whole interior of the pylon is set up as a museum with exhibits and interesting information about the history of the Sydney Bridge, including the former cattery at the top.
Maybe not as adventurous as the bridge climb, but we were quite pleased with the pylon experience. Then we went to bars in The Rocks, A Lowenbrau beer bar that was fun, and then Fortunes of War, advertised as Sydney's oldest pub.
Edit: And I don't think Mimi, jagsfan likes heights...so probably not. π
