The Melbourne Documentary Film Festival kicks off this year on July 9 and runs through til July 16. Part of the lineup of great films on display is Belinda Mason's Constance on the Edge. This is a powerful documentary about mother of six, Constance, learning to adjust to life in Australia after moving here as a refugee from Sudan. In the lead up to the festival, Andrew spoke to director Belinda Mason about what went in to making the film and what documentaries like this mean for Australia's understanding of refugees.
