Help me out Aussie folk that were around in the 80s.

Help me out Aussie folk that were around in the 80s. I'm trying to identify a dinosaur theme park on the Gold Coast from that time period.

I have memories as a kid of going to this rather dingy park. It didn't have much infrastructure at all, but what it did have were giant animatronic dinosaurs. They moved around, and I have vague memories that they were actually being driven/controlled by someone inside the dino. I also remember there was a giant red back spider that the t-rex battled with...

It wasn't Dinosaur Island at Sea World, ans this predated the seaworld attraction by many years. But other than that, I can't find any record of it.

I wonder if it wasn't a permanent setup, but maybe something that moved around the country like a circus?
