Pumped: Who's benefitting from the billions spent on the Murray-Darling? In Australia's most important river system, the water is so precious, it could be liquid gold. Stretching from Queensland to South Australia, billions of dollars in tax payers' money has been poured into rescuing the rivers and streams of the Murray-Darling Basin to save it from environmental collapse. But nearly five years on from a landmark agreement to restore the river, something is wrong. Along the river system many are saying despite all the promises, water is disappearing from the river. Four Corners will reveal how the plan to rescue the Murray-Darling Basin river system is being undermined. Reporter Linton Besser investigates where the money, and the water is going. He finds communities divided. With many wondering how they will survive. And questions whether the billions in tax payers' money has been well spent.

Four Corners is Australia's premier television current affairs program. It has been part of the Australian story since August 1961, exposing scandals, triggering inquiries, firing debate, confronting taboos and interpreting fads, trends and sub-cultures. Its consistently high standards of journalism and film-making have earned international recognition and an array of Walkleys, Logies and other national awards.
