Just because an animal has more than one species, subspecies or variety alone says nothing about its existence. There are two gorillas; mountain and lowland, there are two orangs subspecies; Bornean and Sumatran, there are chimps and bonobos, and apparently a "giant" chimp (?). If bigfoot exists, and I have my doubts, then it could also have subspecies if separated by mountains, oceans, etc. But when I hear about a bigfoot like creature in Australia that really strains credulity. Aside from man and the dogs man brought with him (dingos) the only placental mammals that made it down under were bats, which can fly, and a few rats and mice which hitched a ride on flotsam. Only when Europeans arrived was there a flood of placental mammal species. Bigfoot did not canoe over to Australia.
But surely creatures existed there before the sand banks to the north were walkable. To me it sounds like your ignoring the fact that we have platypus', emus, cassowaries, kangaroos, wombats, wallaby's, quoka's and quolls, and others. Doesn't rule out the fact that a giant ape could have existed here before aborigine's arrived. All along the coasts (barring the north) is a chain of forrests, over west here we have the Darling Range, which when it reaches Pemberton, becomes a forrest of ridiculously huge trees and is very damp. Then over east you have the mangroves and rainforrests, which could have supported an ape in prehistory.
