The 2010–2011 Queensland floods were a series of floods hit Australia, beginning in December 2010, primarily in the state of Queensland including its capital city, Brisbane. The floods forced the evacuation of thousands of people from towns and cities. At least 70 towns and over 200,000 people were affected. Damage initially was estimated at around A$1 billion. The estimated reduction in Australia's GDP is about A$30 billion.
Three-quarters of the state of Queensland was declared a disaster zone. The 2010–2011 floods killed 35 people in Queensland. As of 26 January, an additional nine persons are missing. The Queensland floods were followed by the 2011 Victorian floods which saw more than 50 communities in western and central Victoria also grapple with significant flooding.
