1. NATURAL DISASTERS IN AUSTRALIA

How much can Australia's
economy withstand?
Major natural catastrophes are a heavy
burden even to successful economies like
Australia’s. Data from 2017 indicates that
97% of disaster funding is spent on postdisaster relief and recovery, with only 3% is
invested in mitigating a disaster before it
happens.
Natural disasters in Australia can include
heatwaves, bushfires, droughts, floods, severe
storms and tropical cyclones, earthquakes,
tsunamis and landslides.

Severe convective storms and hail - Icy
cricket balls from above
Losses from severe convective storms, in
particular from hail, represent the most frequent
and (on an annual aggregate basis) the highest
losses for the insurance industry in the entire
Australian natcat business. Seven of the ten most
expensive (inflation-adjusted) insured convective
storm losses in Australia have occurred within the
last 10 years.
Over the last 39 years, the accumulated losses
(all in Australian CPI-adjusted values for 2018)
from severe convective storms total around A$
20.5bn for insured losses and A$ 33.6bn for direct
economic losses. Compared to other perils in
Australia, only losses from flood events reach
similar dimensions. In terms of frequency, losses
from severe convective storms make up about
50% of all loss-producing natural hazard events
that occur in Australia.

FLOODS IN AUSTRALIA
Flood is probably the natural peril Australia
is most aware of. Major floods frequently
isolate towns, create major disruptions to
road and rail links, and can cause death.
Widespread damage to houses and
business premises as well as losses in
agriculture are common. Practically every
year there are flood losses, sometimes with
devastating consequences.
Despite
regular
loss
events,
the
consequences of flooding are still often
underestimated – both in Australia and
around the world.

BUSHFIRES – AUSTRALIA ON FIRE
Bushfires have killed approximately 800 people in Australia since
1851, and billions of animals.

The most destructive fires are usually preceded by
extreme high temperatures, low relative humidity
and strong winds, which combine to create ideal
conditions for the rapid spread of fire. Severe fire
storms are often named according to the day on
which they peaked, including the five most deadly
blazes:
Black Saturday 2009 in Victoria (173 people killed,
2000 homes lost);
Ash Wednesday 1983 in Victoria and South Australia
(75 dead, nearly 1900 homes);
Black Friday 1939 in Victoria (71 dead, 650 houses
destroyed),
Black Tuesday 1967 in Tasmania (62 people and
almost 1300 homes);
Gippsland fires and Black Sunday of 1926 in Victoria
(60 people killed over a two-month period).
In January 2020, it was estimated that over
1.25 billion animals have died in the 2019-2020
Australian bushfire season.

Bushfires in Australia
• In
southeast
Australia
in
recent
decades, bushfire has been the second
biggest cause of insured property loss from
natural hazards after severe thunderstorms.
Victoria is the most exposed state, but the risk
is also high in other regions like the suburbs of
Sydney in New South Wales.
• Bushfires are an intrinsic part of the natural
ecology of the Australian landscape. The
eucalyptus – the archetypal Australian plant –
is particularly fire prone on account of its high
oil content. In the southern part of the country,
the dry months in summer are the most
dangerous time, especially after rain has
increased vegetation growth in the preceding
winter. Unfortunately, the region most prone to
major bushfires, southeast Australia, also has
the highest concentration of people and
insured values.

Earthquakes in Australia
Earthquakes in Australia are infrequent and
mostly moderate in size. At first glance, this
appears to be a much more comfortable
situation than in New Zealand, Japan or the
United States. However, on closer examination
the picture looks different: earthquakes in
Australia could cause insured losses in the same
order of magnitude as in the highest-exposed
regions worldwide.
Australia is not known to be an earthquake
hotspot – but neither was Christchurch in New
Zealand. As it turned out, in Christchurch in
2010/2011 an unexpected series of severe
earthquakes with a magnitude of up to 7.1
surprised even the experts and destroyed large
parts of the city – it was one of the most
expensive insured natural catastrophes in history.

Recognising that governments acting alone
cannot address the challenge of natural disaster
management, the Australian Business Roundtable
aims to support the development of a more
sustainable, coordinated national approach to
making communities more resilient and the
Australian people safer. Munich Re is among the
founding members.
The Australian Business Roundtable for Disaster
Resilience & Safer Communities (ABR) was
formed in December 2012 by the Chief Executive
Officers of the Australian Red Cross, Insurance
Australia Group, Investa Property Group, Munich
Re, Optus and Westpac Group. The CEOs
created the Roundtable because they all
consider having resilient communities that can
adapt to extreme weather events to be of
national importance. This is the first time such a
broad spectrum of organisations has come
together to champion this issue.
