Lightning strikes are the most common natural cause of bushfires.
A 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.
