People's homes are wiped out and livelihoods are destroyed. Poverty, population pressures and environmental degradation mean that increasing numbers of people are vulnerable to natural disasters. In Australia, natural disasters such as floods, bush-fires and tropical cyclones occur regularly across the Australian continent. They cause more than $1.14 billion damage each year to homes, businesses and the nation’s facility, along with serious results to communities. Scientists claim that more natural disasters will occur with worse consequences such as severe cyclones, storms and floods, are expected in the future.

They have influenced, shaped and modified human behaviour, changing the way people live with and respond to the nature. In Australia, billions of dollars have been spent in trying to prevent, prepare for, respond to and recover from natural disasters. Moreover, natural disasters have resulted in enormous intangible losses, causing grief through the loss of life and personal possessions. Examples include the probability or frequency of occurrence of a natural disaster, the number of people killed or injured, or the number of buildings damaged and the extent of that damage.
