1974–75 Australian bushfire season

The 1974–75 Australian bushfire season is a series of bushfires, also known around the world as wildfires, that burned across Australia. Fires that summer burned up an estimated 117 e6ha. Approximately 15% of Australia's land mass suffered "extensive fire damage" including parts of New South Wales, the Northern Territory, Queensland, South Australia and Western Australia.

Statistics
The fires killed six people, approximately 57,000 farm animals, farmers' crops, and destroyed nearly 10200 km of fencing.

The Australian Bureau of Statistics attributed the extent of the fires to "exceptionally heavy rainfall in the previous two years".

Stephen J. Pyne qualified the fire season as the most destructive event in terms of hectares burned among historical fires in Australia, but added that “the 1974/75 fires had almost no impact and much of the damage was found by satellite after the fact.” Nonetheless, fire historian Danielle Clode notes that these fires remain significant for being the biggest bushfire event by area ever recorded. In 2011, retired Australian government scientist David Packham warned that "we are in for one big season" that could repeat the 1974 summer fires.
