Ivan Milat murdered seven young backpackers in the Belanglo State Forest. But were those his only victims?

Investigative journalist Camille Bianchi joins Adam Shand to discuss her gripping new podcast, Back to the Wall, which explores disturbing allegations linking Australia's most notorious serial killer to the dark underworld of Sydney's Kings Cross. In the 1980s and 1990s, vulnerable streetkids gathered at a place known simply as the Wall. Some disappeared. Others survived with stories of predators, powerful men and secrets that have remained buried for decades.

As a New South Wales inquiry examines allegations about Milat's activities before his arrest, Bianchi tracks down witnesses whose accounts challenge the accepted history. Were opportunities to investigate serious crimes missed?

Who knew what was happening? And how much of the truth can still be uncovered?

A confronting conversation about missing children, institutional failures and the survivors who are finally finding their voices.
