John Olsen, Australia's greatest living painter talks to the ABC 7.30 report about his latest body of work Lake Eyre – The Desert Sea, Ruminations on a Empty Landscape. This latest collection of watercolours, a very personal reflection of an ever-changing landscape that Olsen has visited since the 1970's, depicts the results of the recent flooding to the area and the new life that follows. This episode features interviews John Olsen, his gallerist-son Tim Olsen, grandson James and two young artists Luke Sciberras and Guy Maestri fly across the Lake as well as an interview by Edmund Capon, Director of the Art Gallery of New South Wales.
