The document summarizes major flooding that occurred in Queensland, Australia from December 2010 to January 2011. Heavy rains caused four phases of flooding in different regions, with the Fitzroy and Brisbane rivers overflowing their banks. Over 200,000 people were displaced, 20 lives were lost, and damages exceeded $5 billion Australian dollars, affecting many towns and Australia's economy. The flooding was caused by a La Niña climate pattern bringing heavy rainfall and a flash flood in Toowoomba was particularly devastating.
