Taronga Zoo is located next to the Parramatta river, at the opposite site from the centre of the city. It lies on Bradleys Head road in the suburb Mosman. It is easily reachable by bus or by car, but definitely the most scenic way to come to the zoo is taking the ferry from Circular Quay in Sydney's city centre. A round trip ticket, including the entrance ticket to the zoo, will cost you 20-35 aussie bucks. Even if you don't like zoos or when you are short of money, you should take the ferry here at least one time (5AU$ one way), cause it offers superb views on the Parramatta river, the Harbour bridge, the Opera House and the CBD of Sydney.
The lower entrance to the zoo is just next to the wharf. A second entrance is foreseen at the upper edge of the zoo (it is built on the slopes of a hill) for people coming by bus or car. The zoo was started during the 1920's, quite old for a zoo. You can see this at the entrance gate, a nice neo-classical building. Just after the lower entrance is a bassin with seals and sea lions, with a seal show twice a day. Next stop is the African part of the zoo, with zebra's, camels and giraffes. A little bit further they do a bird show twice a day, with parrots and birds of prey. They even half a huge eagle flying over the heads of the public. Amazing!
Other very interesting parts of the zoo are the Asian part with Asian elephants and tapirs, the aviary where you can walk between storks, ducks and pelicans, the excellent serpenteria, with boa's, crocodiles, lizzards, toads and frogs, and the exquisite Australian nightlife experience. The latter one is not a pounding techno music bar full of drunk people (which can easily be found in Sydney, especially on Friday and Saturday evenings), but a darkened hall (your eyes need to adapt to the lack of light for a few minutes) packed with interesting Australian night creatures, like flying foxes, bats, possums, and an aquarium with platypuses. We were unable to spot these strange and timid animals, looking like a cross-bred between a duck and a beaver, but the movement in the water made it clear that they were somewhere.
You can spot many other animals in the park including wallabies, kangaroos, emu's, gibbons, gorillas, foxes, tigers, bears, etc. Last but not least, the zoo offers some spectacular views on Sydney Harbour and the city centre.
