Many people embark on a journey to discover their family's past in order to contextualise their present. But what happens when that journey uncovers something unwelcome?

This was the case for the award-winning Australian writer David Marr. His great great grandfather, Reginald, was an officer of the Queensland Native Police — a force whose task it was to hunt and kill Indigenous people. This discovery has informed David's latest book, Killing for Country: A family story, which traces the structures that supported the violence of Australian settlement. Join David in dialogue with anthropologist and geographer, Marcia Langton, whose ancestors were murdered by the Native Police.
