Koorana Crocodile Farm is a working crocodile farm east of Rockhampton, set up around guided tours rather than a zoo-style wander. The visit gives a close look at saltwater crocodiles at different ages, from hatchlings to large adults, and explains the farming, conservation, and safety issues that surround the species in northern Australia.
It is a practical half-day outing if you have a car and want a wildlife stop that is specific to central Queensland. The farm setting is plain, but the guides make the difference: feeding demonstrations and handling explanations are the reason to go. Check tour times before driving out, since access is usually by scheduled guided visit.
