Singer-songwriter Stan Walker opens up for the first time about the horrific abuse and neglect he suffered as a child and young person, in the hope of helping other victims. His music career was launched when in 2009, at 19 years old, he won Australian Idol. Since then, he's released five albums and won numerous music awards. The truth about his childhood in Tauranga and Australia has never been told - until now. His memoir Impossible will be in shops next week and he's touring with Mike King next month.
