There's nothing quite like a raging bushfire. You can have ample warning and still it can overrun you.
When driven by a strong westerly wind that skips trees and lights gaseous fireballs created by oil evapourating from the eucalypts, it is a frightening thing to behold.
Everything is scorched, native fauna the most pitiful sight as koalas and kangaroos are burnt, unable to escape the fury.
As for the flora, pics 2 and 5 clearly illustrate what's left after this fire through the Central Coast, just north of Sydney though its pall cast a shadow over Sydney's northern suburbs.
The moral is, don't throw cigarettes out of the car window, as I have seen some thoughtless people do on occasions, or even contemplate lighting anything, even a seemingly protected back yard barbecue. As evidenced here, the price is too high to pay.
The bushfire season obviously goes through summer, November through February, and the worst time is usually Christmas/New Year. In drought conditions, which is a regular occurence, the danger period is much longer.
This is a time of extreme danger, and not only in the bush. The Blue Mountains are often hit and, because Sydney has many natural bush parks - and the oil in our ubiquitous eucalypt trees is highly flammable - raging fires can come right into the suburbs. Obey the warning signs, do not drop cigarette ends, do not light fires if a fire ban has been declared.
