Earlier this month Australia's most decorated soldier Ben Roberts-Smith lost his defamation case against three newspapers who reported he had murdered civilians in Afghanistan.
While not a criminal trial, the court judged him responsible for the deaths of four Afghans while deployed during 2009-2012.
Investigative journalist Nick McKenzie brought the allegations to the public eye and has spent five years working on the story. Next week he is releasing a book called Crossing the Line.
Roberts-Smith continues to profess his innocence.
