'Superhighways' used by a population of up to 6.5 million Indigenous Australians to navigate the continent tens of thousands of years ago have provided. ....

For the first human inhabitants of Sahul the super-continent that underlies modern Australia and New Guinea camping at the next spring, stream, or rock shelter allowed them to thrive for hundreds of generations. Those who successfully traversed the landmarks made their way across the continent, spreading from their landfall in the Northwest across the continent, making their way to all corners of Australia and New Guinea. By simulating the physiology and decisions of early way-finders, an international team of archaeologists, geographers, ecologists, and computer scientists has mapped the probable superhighways that led to the first peopling of the Australian continent some 50,000-70,000 years ago. Their study, published in ....
The continent’s larger coastal plains could have seen the Indigenous population peak at triple the highest previous estimate according to the groundbreaking study. ....
Low sea levels once linked Australia and New Guinea into a land called Sahul Experts think this was first settled between around 70,000–50,000 years ago Researchers used advanced modelling to predict how humans first settled Sahul Simulations accounted for factors such as landscape features and water sources Many of the migration paths they found matched known Aboriginal trade routes ....

Superhighways used by a population of up to 6.5 million Indigenous Australians to navigate the continent tens of thousands of years ago have been revealed by new research using sophisticated modelling of past people and landscapes. The new insights into how people not only survived, but thrived, in harsh environments provide further evidence of the capacity and resilience of the ancestors of Indigenous people, and help paint a picture of large, well-organised groups navigating tough terrain. The peopling of Sahul the combined mega continent that joined Australia with New Guinea when sea levels were lower than today could have taken as little as 5,000 years as people moved from the far northwest, all the way to Tasmania in the southeast. ....
