A wildfire, wildland fire or rural fire is an uncontrolled fire in an area of combustible vegetation occurring in rural areas. .Bushfires are frequent events during the warmer months of the year, due to Australia's mostly hot, dry climate. Each year, such fires impact extensive areas. ... For thousands of years, Indigenous Australians have used fire to foster grasslands for hunting and to clear tracks through dense vegetation. .The 2019–20 Australian bushfire season has burned an estimated 6.3 million hectares, destroyed over 2,500 buildings and killed 25 people as of 5 January 2020, with a further six missing in the state of Victoria. The bushfires are regarded by some as one of the worst bushfire seasons in memory.
