I think each CFS Region has an incendiary gun, as well as few DEH brigades....
Load the gun with a thing that looks like a ping pong ball (but filled with pot permanganate, I think) once loaded, the ball is injected with glycol (or was it the other way round, glycol in the ball..injected with pot permanganate..?) anyway, once the two chemicals start to mix, the gun is fired...appears it can go 30-40 metres...the reaction progresses, gives out heat, and (hopefully) you get a fire.....
It is easier than trying to get through the blackberrys & broome with a fire lighter in hand....
