Hamm told the ABC that "nature called and Cliff [Coulthard] walked up this creek bed into this gorge and found this amazing spring surrounded by rock art." "A man getting out of the car to go to the toilet led to the discovery of one of the most important sites in Australian pre-history." He explained that while looking at the spring, they saw a rock shelter with a blackened roof."Immediately when we saw that we thought, 'Wow, that's people lighting fires inside that rock shelter, that's human activity,'" he said, admitting he had no idea it would be so old.
Lead author Giles Hamm, a researcher from La Trobe University, collaborated with Duncan Johnston of the Adnyamathanha Traditional Lands Association and Traditional Owner and elder Cliff Coulthard, who was told about Warratyi by his elders as a teen.Wilsons Promontory National Park has an early history of Aboriginal occupation with archaeological records dating back at least 6500 years.The Prom had (and still has) spiritual significance for different Aboriginal groups, who knew the area as Yiruk or Wamoon.The oldest known proof of Aboriginal settlement in ancient Australia was stumbled upon accidentally after a car full of researchers pulled over for a toilet break.Known as Warratyi by the Adnyamathanha people of the Flinders Ranges in South Australia, a rock shelter was found to contain artifacts and the remains of megafauna, dating human settlement in the area back at least 49,000 years.The official records that document this control are of vital significance, particularly for those people who were removed from their families and settled elsewhere in the State.
