How do bushfires start in Australia?

Hot, windy and dry weather certainly influences and increases the risk of bushfires. But what are the most common causes of a fire actually starting?

They’re mainly from human-related incidents, according to data from the Australian Institute of Criminology (the Institute)1.

It reports that the majority of bushfires are started either intentionally or unintentionally, by people.

The Institute found the top attribution was “suspicious” followed by “accidental”.2: Suspicious 37%

  • Accidental 35%
  • Deliberate 13%
  • Natural 6%
  • Reignition/spot 5%
  • Other 4%

Here are some of the most common causes for bushfires in Australia, according to fire investigators3:

  • Smoking or a discarded cigarette butt
  • Burning off/debris
  • Arson

The Institute says while figures vary, around half of all bushfires in Australia are either known to be deliberately lit or are considered suspicious.

  • Railway cause

Albeit surprising, trains can be a cause a bushfire, the ABC says. Burning carbon embers from train engine exhausts or brake failure can throw sparks which can ignite dry vegetation near the tracks. Other causes include:

  • Campfires
  • Equipment use including chainsaws, mowers and angle grinders
  • Lightning
  • Miscellaneous including power lines, glass refraction, electric fences and more
