team at RMIT’s Centre for Risk and Community Safety that
undertook the review of the policy for the Bushfire Cooperative
Research Centre
In the summer of 1909/10, my Great Grandparents faced
the risk of losing everything to a bushfire. Emily and
Charles Handmer lived on a farm 6 kms north of Knowsley near
Bendigo, by the state forest on a road now known as Handmer
Track. All the men were interstate. The five
women and girls used buckets of water to put out ember attacks on
the bark roofs of the farm buildings while Grandfather lay ill
inside. Neighbours came, and with their help – and a
wind change - the buildings and farm equipment were
saved.
They stayed and battled the fire, and never considered
leaving. This was long ago and they did not have the
means to flee rapidly. But it highlights the reality for many
rural people: that the home is closely tied to livelihoods,
and abandoning it can mean a lot more than an insurance claim and
the shock of loss. The welfare of livestock must be
considered. There is also the reality that it may be
impractical and dangerous to evacuate with the risk of trying to
drive through heavy smoke or being caught in the open by the fire
front.
Reports from the Black Friday fires of 1939 also mention
examples of the successful use of buildings and
“dugouts” as life-saving shelters. The threatened
settlements were mostly associated with timber-mills scattered
through the Victorian forests. Many died fleeing, and the survival
of people was considered ‘miraculous’.
However, most stories of survival tell of people sheltering in
structures, and being vigilant in extinguishing embers.
Bushfire scientists also offered advice, drawing on their
experience and research. Typical is the advice in a
1961 publication entitled “Bushfire Prevention Hints for
Country Men and Women”. The author states; “if all
possible preliminary precautions have been taken before the fire
… the house and its environs should be the safest place of
refuge.” He adds: “Until a house actually catches
fire from flying fire-brands (and with the precautions that have
been mentioned we can hope this will not happen) the safest place
for children and invalids should be in the house.” The only
evacuation this author mentions is possible evacuation to a
burnt-out field as a last resort.
Staying and protecting homes, assets and people has a
history in rural Australia long predating the official “Stay
or go early” policy. Australian rural dwellings
have been timber with corrugated iron or tile roofing
surrounded by gardens that often act to help shield buildings from
fires and embers.
This rural experience has formed part of the basis
for the policy we know as “Prepare, stay and defend, or leave
early”. Historical evidence in Australia has shown that
the most dangerous option, and the cause of most fatalities, is
last minute evacuation. The purpose of the approach known as
“Stay or go early” has been to avoid these dangerous
evacuations, by either leaving early before a fire threatens or
staying and defending. It has become a key part of bushfire
community safety across rural and urban Australia.
No approach is risk free
Early on in the life of the Bushfire CRC we reviewed the
evidence for the approach. This evidence is drawn from
scientific studies, coronial inquests, post-fire research
(particularly after Ash Wednesday in 1983), oral histories of rural
people, fatality data, and the experiences of fire fighters.
It indicated that the policy both improved the safety of people and
reduced property loss. No approach is risk free, and successful
implementation of the policy is subject to a number of conditions
concerning knowledge, fire intensity, water supply, the
defendability of the property, and timely warnings for those
planning to leave.
There are three important pieces of evidence:
that houses catch fire from embers, and houses can be made
resistant to ember attack; that well-prepared people can save
houses; and that late evacuations are very dangerous as they may
take people into areas of zero visibility or the fire front.
Our review was published in 2005. We continue to examine the
policy in the light of changes such as new fire experiences, the
expanding urban interface and “tree changers”, changes
in people’s expectations, absentee landlords, changing
building and garden styles, and an apparent increase in fire
weather risk.
Seeking the safest approach
The Saturday 7 February fires occurred in fire weather
conditions that appear to lie well outside our
experiences. In the aftermath of the fires it is
obvious that most aspects of our fire and emergency management, and
all our standard policies and practices should be subject to major
review. “Stay or Go early” is no exception.
Some people are proposing apparently simple solutions, including a
national warning system – important but we need a more
reliable mobile network to carry warnings; new building regulations
– but maybe we should wait until the building forensic work
from the fire is complete; or universal mandatory evacuation.
In an ideal situation, mandatory evacuation might be
effective. However, things are rarely ideal.
Forced evacuations often take place at the last minute as
the fire front arrives, forcing people out into the most intense
part of the fire. In addition, some people refuse to
go, others are simply missed by the evacuation order, while others
will attempt to go back into the fire affected area to collect or
save their pets, children and properties. We know this
because almost all the published material on evacuation concerns
how to get people to leave and what makes them more or less
inclined to do so – rather than asking the question:
what is the safest approach given that all approaches have
flaws?
