Behind the Walls is a ground-breaking six-part podcast series that for the first time takes listeners on a journey into NSW prisons and parole offices. Podcast host Michael Duffy, a crime author and former journalist, spent six months recording the interviews at 11 correctional centres and four Community Corrections offices, where staff manage offenders on community orders. Thirty correctional officers from prisons including Bathurst, Lithgow, Cessnock, Cooma and Long Bay share their stories of what really happens when people are sentenced to prison.
