I've been there. But without the girls!

I would HIGHLY reccommend it. Make a day of it though cause it does take a while to get around it.

We were going to go down for Christmas last year but DP's family decided to come up to us. A visit to Dubbo Zoo was definately on the agenda. We will get down there soon!

But yes, I think it would be great for your little man! Esp if he is a real animal kid.
