More than 700 suspicious fires have been lit in Western Australia this bushfire season, prompting authorities to urge people to dob in an arsonist for a potential $50,000 reward.
Twelve people - 10 of them juveniles - have been charged with deliberately lighting fires in WA since a task force was launched in mid-December.
With the cost of fighting bushfires in the state estimated at $1.6 billion a year, two state ministers are pleading for people to consider the potential damage of starting fires.
"Lighting a bushfire is one of the lowest acts you can do," Emergency Services Minister Joe Francis said.
"The fear, panic and stress of seeing a bushfire bearing down on your house, and having to flee for your life, is truly horrifying."
