The trouble is when the wind blows the foliage can send out huge tongues of fire 50 meters well into the 1000 degrees Celsius level.
Sadly these videos don't show the reality

. Been doing bushfires professionally for 20 years and never seen a video that gets it right. I was at Marysville 4 months after and very little survived. Saw fire travel through sheep paddocks 1km width with very little slowing down . Not much you could do in that weather environment
Ok's gone silent , hmmmm whatever can the mater be !!??
I fought a spot fire started from a bushfire up at Barrington tops area in the early seventies when i was a kid, cinders kept landing and it kept reigniting so we had to get out fast. You know you have a NAZI government when all the trails while well kept , roughly have no good directive signs such as OUT THIS WAY but the most is even the small fire truck that got through (they knew we were in there) kept being stuck in thr special creek and deep furrow crossing dips in the road. All they are doing is preventing ordinary cars getting away, this was an early tray top 2 ton. Does OK but only short car like vehicles can actually get through. While the fire and smoke started to rise over the hill we had to push it out of one of those tight jammed dips. They are a murdering prick everywhere so people cannot get away if the cops are chasing them, that's all that's in that in doing the tactics that way. Never bother to think of fire coming at 50 - 100Km wind !
