A 31 year old man has been charged with leaving his campfire unattended
which lead to the Lake Repulse fire.
The Bicheno fire was started by a lightning strike.
The Forcett (Dunalley fire) was started by a smoldering tree stump. Locals thought the fire had been put out days before the big fire but it seems that the was still slow burning in the root system which flared up.
So no intentionally lit fire at all.
