Make your own way to the Irukandji Shark and Ray Aquarium at the time of your choice and join your guide for your tour.
Choose to don either the wader pants — which keep you completely dry — or a wetsuit with booties (the pools are heated to a comfortable 76°F or 24.5°C). Start by visiting the smaller fish, including juvenile Port Jackson sharks, tropical fish, seahorses, and eels, all located in the Bamboo Shallows exhibit.
Move on to Fiddler Flats to see the fiddler rays, who get excited when you offer them food. Ray Lagoon is home to larger species including eagle rays, zebra sharks and the leopard whip rays. Your guide gives you a close look at a stingray mouth and the rest of the rays often come over to see what's happening.
Finally, meet the big fish when you stop by the tawny nurse shark tank. Sometimes referred to as the koalas of the ocean, these sharks can measure about 10 feet (3 m) long and spend a lot of time sleeping.
When your tour ends, you can remain on your own for another look at your favorite creatures.
