Unfortunately you can't get to the site of the original cache at the moment as Fort Denison is closed indefinitely for maintenance. Instead, you can log the cache with a photo of you and your GPS for the Fort in the background.
Yes, this cache is in a National Park, but you won't find much wildlife here. You can have a very pleasant time at this spot which gives you one of the best views of Sydney Harbour. Something special happens here at the same time every day and there is a plaque nearby. To log this cache message me the last line on the plaque, and log a photo of you on the spot. Extra clever people can tell me where this cache gets its name.
(We went there for brunch and it was a great start to the day)
Thanks to AlternateRoute for letting me adopt this virtual cache.
