Marineland Crocodile Park

Aquarium in Green Island

While this family-owned, tropical-themed aquarium has plenty of fish, turtles and beautiful artefacts on display, it's Cassius, the world's largest croc in captivity, that is the star attraction; he's believed to be over 110 years old and is 5.5m long. Cassius and pals are fed daily at 10.30am and 1.30pm, which is when you'll see the most activity. Your ticket entitles you to re-entry throughout the day.
