Risk ​Ass​essment Report​


​This district risk assessment report summarises the results of the State Risk Project risk assessment workshops in the South West Emergency Management (EM) district. It co​​vers five priority hazards, as identified by the South West District Emergency Management Committee (DEMC). The workshop series was conducted between September 2015 and November 2016.​

District Risk Profile​​

​​

​​​​​​Re​​​port highlights​​​​:

  • The results for the five hazards assessed reveal that:​

- ​No extreme risks​​;

​​- 25% of the risks were assessed as high​​;

- 5% of the​ risks could cause catastrophic consequences​.​​​

  • ​​​​Flood ​has the greatest number of high (31%) and medium (38%) risks. The flooding scenario was expected to cause damage to roads and bridges and disruption to major freight routes. Disruption to travel on the South Western and Forrest Highways were of particular concern due to the number of bridges that could be damaged with expected financial losses of more than $62 million.


  • All ​​assessed hazards in the South West pose a risk to human life with the majority (60%) of the risk statements being high risks. As the Dunsborough bushfire scenario occurs in the holiday period a significant number of visitors would be in the area that m​ay not be familiar with bushfire conditions or local roads and confusion could lead to individuals being trapped.


  • A ​foot and mouth disease outbreak in the South West would cause catastrophic impacts to the economy. Farm revenues, meat exports and the meat processing industry would all be impacted, leading to business failure and significant costs associated with animal destruction. A potential foot and mouth disease outbreak would have national and international implications and could take years to recover.


  • Electric​​​ity supply is impacted by multiple hazard scenarios (bushfire, flood, storm and electricity supply disruption). One of the fires in the bushfire scenario has the potential to significantly damage the Muja Power Station and enter the coal mine which supplies the power station, disrupting generation. This would require recovery activities resulting in considerable costs (>$625 million). Wind damage from the storm and damaged electricity ​assets from the flood would result in high costs and cause supply disruptions.
