Great way to spend an afternoon. Half a day should be enough time to get around and see the main things.
Some of the highlights for us were the Gibbons on their island. Be sure not to miss them.
A couple of other things worth seeing are the flying foxes on the way out are also definitely worth a visit ( mainly since you don t see those very often) and also the reptile house (very nicely done with a few different terrariums and very active little guys to see).
