Australias Great Flood (DVD), National Geographic, Documentary

2011 has been a year of unprecedented natural disasters; from the killer tsunami in Japan to earthquakes in Christchurch and Thailand. But it all began in Australia, when weeks of torrential rain and cyclones battered much of the country. After a decade of crippling droughts, said to be the worst in a century, Australia's climate switched. From September 2010, much of eastern Australia experienced it's wettest spring on record. Crops were soaked and water catchments were full for the first time in years.
