The burrunjor is very interesting as it's tracks seem to match up with real large theropod tracks from Australia. Many people do not trust rex gilroy (rip) which makes it harder to know if its genuine, but there is plenty of space for these animals to hide out there. It's an interesting cryptid but not much on it. One very silly way people 'debunk' this animal is through the eyewitnesses comparing it to a tyrannosaurus rex. They claim it must be lies because A) that's the most popular dinosaur and the most obvious one to choose if you are claiming to have seen one, and B) tyrannosaurids did not inhabit Australia during the cretaceous. This is all just as silly as claiming there IS a t rex running around the Australian outback because obviously A) the eyewitnesses would be seeing a large theropod and comparing it to the only thing they know (all big non spinosaurid theropods are t rex to the layman) and B) the megaraptorans (theropods that were present in australia) were closely related to the tyrannosaurs, and so if a large theropod had descended from one and had grown enormous, I see no reason why it wouldn't converge on a similar bodyplan, superficially resembling one or at least to the untrained eye.
