The Black Saturday bushfires were a series of bushfires that either ignited or were already burning across the Australian state of Victoria on and around Saturday, 7 February 2009, and were among Australia's all-time worst bushfire disasters. The fires occurred during extreme bushfire weather conditions and resulted in Australia's highest-ever loss of human life from a bushfire, with 173 fatalities. Many people were left homeless as a result. As many as 400 individual fires were recorded on Saturday 7 February; the day has become widely referred to in Australia as Black Saturday.
