Welcome to Qld. There is another small wildlife park on the coast and it is run by the government. It has been quite a few years since we have been there though, anyway click the link and check it out. David Fleay Wildlife Park - EPA
They do have a website: Welcome to Currumbin Wildlife Sanctuary
Not cheap to get in, but I know when I have been there they do have discount for motoring
organisations (like RAA here in SA).
