This time, I bought the 3-attraction pass, which was a great deal. I visited Healesville Sanctuary (the bird show has two performances, one in the morning and one in the afternoon, with different content, so I recommend seeing both; the platypus is also a must-see), Sovereign Hill (this pass included a mine tour, and you can choose your time slot when exchanging tickets at the entrance; Chinese-language tours are available), and SEA LIFE Melbourne Aquarium (you can see penguins up close, separated only by glass; there are many species and a huge crocodile).
