Migration routes of ancient Australians

Scientists have traced the paths that ancient Indigenous Australians probably took as they moved through the mega continent of Sahul some 60,000 years ago. Their models suggest that the first visitors arrived on the shores of western Australia and, within 6,000 years, settled across the entire continent — from the tropical north, now Papua New Guinea, to as far south as Tasmania. Many of the ancient migration routes they modelled seem to match up closely with nineteenth century stock routes and Aboriginal trade lines.
