However, we know that ancient humans got to Australia and they did not walk there. Assuming that we can dismiss the possibility that they flew there that really only leaves one possibility.
The distance between Timor and the Northern Coast of Australia was only 150km about 50,000 years ago when it was likely the first Aboriginals arrived.
I personally believe that people managed to get to the Americas before the Clovis by sailing along the coast of what is now Alaska and British Columbia which at times even at the height of the Ice Age would have had ice free refuges.
An earlier arrival of humans in the Americas would account for the "australoid" features in human remains found in Brazil. Such features say 30,000 to 20,000 years ago were part of the North and East Asian populations. However those features have disappeared in those populations since then.
