The Darling River wends its way through 1500 kilometres of Australian Outback. To the Barkindji people of far western New South Wales, the river channel marks the course of the Naatji -- the rainbow serpent. It has sustained cultures and communities for thousands of years. But the River is in danger, and the people along its course face an uncertain future. In a four part series Voice of Real Australia takes you up the Darling River, the Forgotten River, and introduces you to the people who are fighting for its life.
