the outstanding Aquarium of Western Australia in Perth

Definitely! That's not just another water tank stuffed with fish. It's actually an outstanding aquarium, that takes you on a 98m underwater walk with around 2500 examples of 200 marine species. And if you're feeling courageous, you can snorkel or dive with the sharks in the giant aquarium (for around A$120 including the equipment). So, it's worth the effort of dragging yourself away from the beach and getting out there, at Hillarys, approximately 15km northwest of the city.
