During our trip to Sydney in September 2010, we spent time in two different wildlife exhibitions. We spent an entire afternoon in the Taronga Zoo, which provides stunning views of the entire city.
In addition, we spent time at the Sydney Wildlife World, which is located in Darling Harbour. During our visit, my wife actually had the opportunity to pet a kangaroo.
I've combined my photos into an Animals group on Flickr, and included some more examples below the break.
