PILBARA, WESTERN AUSTRALIA—Stone artifacts, animal bones and charcoal at the Ganga Maya Cave suggest that the site was used by humans more than 45,000 years ago, and may have been visited repeatedly up until 1,700 years ago. Is this Australia’s earliest habitation site? “We have some old the dates and I would prefer to get other dates before I make those kind of claims. It is certainly a very old site,” archaeologist Kate Morse from Big Island Research told The Sydney Morning Herald. “I think it is an area that people have traveled into to start exploring Australia. They have come from Southeast Asia across the water and arrived in northern Australia and opportunistically made their way around the coast and inland following river systems inland,” she added.
