A bushfire is a wildfire that burns out of control spreading across vegetated regions of bushland. In order for a bushfire to be catastrophic, the right conditions must be present. Most bushfires happen in times when temperatures are high. In addition, conditions must be dry. Areas with dense undergrowth, as can be found in south-eastern Australia, are the most vulnerable to bushfire. Bushfires often start when dry winds blow inland from central Australia. While the winds bring dry weather, they also provide ventilation for the flames.
Bushfire incidents in Australia can be caused in many different ways. The causes of ignition can be split into two groups, ‘natural’ and ‘human influence’. Lightning strikes are the main way bushfires are started naturally. There are, on average, more bushfires initiated due to lightning strikes than any other individual cause, accounting for approximately 26 percent of all bushfires.
The vast majority of bushfires, however, are generated by the actions or influences of humans. On occasions, a campfire can develop into a bushfire, if the campfire is left unattended or not properly extinguished. Some farmers burn vegetation on their properties to rid the land of crop debris, control weeds and remove rubbish. These fires are referred to as agricultural burns and can lead to bushfires when they are not administered carefully. Agricultural burns are responsible for about 15 percent of all bushfires. Machinery or equipment that generates heat or sparks can potentially act as a catalyst for bushfires. Some machines notorious for triggering bushfires include chainsaws, grinders and slashers. The exhaust from vehicles may also cause fires. Cigarettes which have been discarded irresponsibly have the capacity to ignite bushland, although only seven percent of all fires begin in this manner.
