The remains of the first known Australian, Mungo Man, have returned to the Willandra area of New South Wales, where they were discovered in 1974.

They were accompanied by the remains of around 100 other Aboriginal people who lived in the Willandra landscape during the last ice age.

But negotiations between Indigenous ancestors and Academics over what happens to the body next are continuing.

Sam and Nick spoke with Dr Michael Westaway, Senior Research Fellow, Research Centre for Human Evolution, Griffith University.
