Lessons learned from Australia's wildfires


The bushfires in Australia, of which I've written in the past couple of days, continue to burn, and the death toll continues to rise. As I write these words, it stands at 181, and police have warned that it may rise steeply as they enter areas that they've been unable to reach until now. A final total of 300 or more is apparently feared.

There are also important lessons being learned. People died through doing exactly what they had been told to do - horrifying evidence that even the authorities hadn't read the situation rightly.

The head of the New South Wales fire brigades has commented on this.

MILLIONS of people living near bushland can no longer expect emergency workers to save them in the face of ferocious megafires, the head of the NSW Fire Brigades has said.

"We can't be the safety net all the time. Our resources are stretched and we won't be there," said its Commissioner, Greg Mullins, yesterday.

He said lessons would be learnt from Victoria's experience and added to the strategies he and other other international fire chiefs discussed after firestorms in California and Canberra, and the Sydney 2001 bushfires.

"If this is the way of the future - savage winds, high temperatures and low humidity - it is clear it is going to get worse and it is going to take all levels of the community and government and agencies to work together," he said.

Firefighters' two biggest enemies are complacency and a lack of knowledge in the community but, as fires become bigger and more destructive through the effects of climate change, people must become more self-sufficient, he said.

"You must prepare. You must cut the bush back from your home. It's not good [enough] to think if there is a fire down the road: 'I think I'll go now.' It's emerging a lot in Victoria died leaving in cars and on foot."

In an early lesson from Victoria, Mr Mullins said NSW fire services were considering using SMS warnings - for which the technology is already available - and asking TV and radio stations to play an emergency warning siren weekly so that people become familiar with it and will respond quickly when there is a fire.

"In Queensland, radio stations play it regularly as a test cyclone warning. We haven't done it for fire mainly because we don't want people to panic and evacuate. We are now thinking we might need to get people used to it," he said.

Mr Mullins did not think anyone could have prepared for the scale of the Victorian situation, but said that he hoped it would be a "huge wake-up call" to people who were complacent about their own preparations for possible fires, especially in metropolitan bushland areas.

"I'm concerned as the commissioner of the urban fire service in the state that we see over and over that people are gobsmacked at the speed of bushfire and have made no preparations. You ask: 'Did you get the messages?' and they say yes, but they didn't think it would happen to them in suburbia."

New tankers with special spray systems to protect tyres and fuel tanks plus reflective foil curtains which pull over glass areas, introduced by Australian brigades after extensive research, performed well in the Victorian fires.

Flames had passed over two or three tankers and no one had been hurt, he said.

. . .

[The NSW Rural Fire Service commissioner] Shane Fitzsimmons ... said it would be "improper and insensitive" to draw too many conclusions so early after the fires, but the best scientific research and experience available indicated that the home was the safest place of refuge during fire, and fleeing at the last minute was the most dangerous choice.

However, many of the 1.4 million homes on the "bushland interface" in NSW would not be able to be built today if the state's bushfire planning regulations, toughened five years ago, were applied today, he said.


Important words, for us to heed in other parts of the world as well. God forbid we should ever be in such a disaster: but if we are, we can at least learn from the tragedy presently engulfing Victoria.

  1. To be fair, people didn't die so much as a result of doing what they were told; the problem is that this bushfire is so much worse than anything previously encountered in Australia, through a combination of weather conditions and poor forest management over the past decade or so. Local residents have been saying for a long time that the bushland in the area has been a tinderbox waiting to go up. This was just the worst possible time for that tinderbox to light.

    In most other situations, staying in your home is the right decision. And in any case, the ferocity of this fire was such that you had an option of evacuating while the fire was still a hundred kilometres away, or not at all. With the speed of the spread, by the time you knew the flames were approaching, it was too late to move.

  2. Wonder if window film might prevent the blowing out of windows due to heat? That, combined with a metalized reflective surface on the glass might buy a bit of time.
    The heat level must have been incredible, the house remains seem to be nothing but white ash and incombustible like metal roofing. And among it all, a lot of tree tops apparently unburnt. Strange.

  3. I live in SE Colorado , we dont have brush . With that being said we do have a lot of grass, crop residue , ect.. , even in a grass fire the survivable is to evacuate structures ahead of the fire . The closest thing i can imagine in the USA would be in southern California where we take resoruses to tell folks to get the hell out well ahead of the fire . I cannot imagine a time or place where by " shelter in place " is a good strategy for fire. Folks say we need laws to keep folks from building in fire prone areas , and i disagree . What we need are clearly maintained firelines at a defensible point , and no fire service will tresspass beyond that . If they want to build where no one can save them let them , and let them pay insurance if they can get it , and the price if they choose to stay . Ill say the same for folk who live in " hurricane zones " and expect insurance or taxpayers to rebuild for them ( no offense peter i know you paid your bill yourself ) . Folks feel free to live in " danger zones " but dammit research and know that you are , then foot your own bills .

  4. With some of the fires moving at about 40Km in around 5 minutes, people either made the choice to go very early, stayed and defended their homes or tried to leave too late.

  5. just read this very interesting article from a bush-fire survivor (of the canberra fires in 2003). Some very useful info in it -
