A land of rivers and flood plains, paperbark and eucalypt woodlands split by ancient sandstone cliffs - this is the home of Bill Neidjie and the Gagadju people. Part of Kakadu National Park in Australia, the region is an ever-changing vista that rules the lives of the Gagadju people. They divide their year into six seasons which can be heralded by a plant coming into flower, dragon flies swarming, a change in wind direction or grasshoppers singing to welcome a new season.
