Drought, flood, storm and fire define life in Australia, the driest inhabited continent on earth. Drought grips the nation regularly with some spells lasting over a decade, and in many areas, arid conditions brought about by low rainfall remain common. A country of great extremes, Australia is locked to the cycles of El Nino and La Nina, which bring alternating dry conditions and wet conditions to the east coast every few years. This compelling four-part series explores the apocalyptic forces that nature visits on this ancient island and looks at how millions of years of evolution have uniquely prepared all Australian life for these dramatic and often devastating challenges.
