Great family day out, if the kids like animals.
Friendly and professional staff, they are happy to answer questions and point you in the right directions. Animals focus mainly around Tasmanian and Australian species, however there is a surprising array of animals. Enclosures are not world class, however animals look well cared for and keepers are seen tending to the animal needs all day long.
It's easy to catch presentations and feeding times, and I highly recommend buying food to feed the fish and kangaroo/emus, if you and your children are not afraid of animals.
Well worth a visit, and if you tie the trip in with a visit to the caves, it's a great day away.
The cafe has decent food as well.
