What is a bushfire?

A bushfire is a wildfire that burns out of control spreading across parts of bushland. In order for a bushfire to be catastrophic, the right weather must be present. Most bushfires happen in times when the temperature is high. Weather must be dry. Bushfires often start when dry winds blow in from the middle of Australia. While the winds bring dry weather. Trees such as eucalypts are especially dangerous to fire because their leaves have a highly-flammable oil. Dry leaves and bark are especially flammable. Bushfire’s are usually in subtropical areas of Australia but in summer they can be anywhere.
