Bushfires are often started by any of the following:

  • lightning strikes
  • campfires not being put out properly
  • sparks from a car's exhaust if surrounding vegetation is extremely dry
  • arson
  • damaged power lines

Conditions that cause the bushfire to increase in intensity are excessive heat and prolonged heatwave or drought, which has caused the vegetation to become tinder-dry, as well as strong, hot winds.
