Bushfires occur through a number of factors:
- arsonists
- lit cigarettes tossed away
- prolonged heat and/or dry weather which causes vegetation to ignite easily
- strong, gusting winds
- a sudden change in wind direction
- lack of controlled burns prior to bushfire season
- faulty power lines
- lightning strikes

∙ 11y agoA bushfire primarily requires fuel and some method of igniting it. The method of ignition could be by man, either purposefully (vandalism) or accidentally, e.g. campfire left burning, a tossed cigarette, a glass bottle which focuses the sun's rays on the dry fuel.
Fuel may be created through prolonged drought or dry conditions, which causes vegetation to dry out. This is why Australia is so prone to bushfires - drought is a common problem. Strong winds can fan the flames into a raging inferno, or a wind change can take a narrow fire front and turn the flank around into a wide front which is even more destructive and harder to control.
Lightning strikes are a natural cause of bushfires, and one of the major causes.
Another man-made cause is faulty power lines, when lines may start to arc, causing flying embers which quickly light dry vegetation.

The campfire will most likely send sparks out near the grounds near it. If there is flammable material nearby it has a chance of catching fire. The fire will ignite and spread to more material nearby and you get a brushfire.

∙ 10y agoThere are numerous factors that cause bushfires to start.
- Statistics indicate that most bushfires are caused by lightning strikes.
- Bushfires are, unfortunately, also commonly caused by man's activities, whether arson or unintentionally lighting the fires such as by tossing cigarettes out of car windows, or not extinguishing campfires properly.
- The intensity of bushfires is increased by dry vegetation, often after a period of heatwave, together with strong, gusting winds, and absence of precipitation
- Faulty power lines are also often a cause. Sparking and arcing from these powerlines easily ignites into bushfires.

How common are wildfires in Australia?
Bushfires, as they are properly called in Australia, are very common, particularly during the summer months. Parts of southern Australia, where the summers can be very hot and dry for extended periods of time, are particularly bushfire-prone. Bushfires occur throughout Australia, wherever the vegetation becomes dried out and easily ignited during heatwaves or drought. A common cause of bushfires is when tinder-dry vegetation is struck by lightning.There have been several significant bushfires that have caused great devastation and loss of life in Australia since European settlement. The Black Friday bushfires (1939), Ash Wednesday bushfires (1983), Canberra bushfires (2003) and Black Saturday bushfires (2009) have been among Australia's worst natural disasters.
