We first profiled official war artist Ben Quilty last September as he worked on portraits of Australian soldiers who'd served in Afghanistan. Quilty spoke then of the strong bonds he'd formed with many of his subjects, including some of the elite special operations troops who he says revealed a depth of emotional distress that shocked him to his core. Six months later, Quilty's exhibition is now on tour and attracting much interest. In the intervening time, his own journey from artist to angry advocate has led him to argue for better treatment for returned soldiers who he says continue to suffer from their time in the war zone.
