This district risk assessment report summarises the results of the State Risk Project risk assessment workshops in the Great Southern Emergency Management (EM) district. It covers six priority hazards, as identified by the Great Southern District Emergency Management Committee (DEMC). The workshop series was conducted between May and July 2015.
The results for the six hazards assessed reveal that:
- 1% of the risks were assessed as extreme;- 18% of the risks were assessed as high;- 5% of the risks could cause catastrophic consequences.
- 1% of the risks were assessed as extreme;
- 18% of the risks were assessed as high;
- 5% of the risks could cause catastrophic consequences.
Damage to private and commercial buildings and contents from bushfire would be expected to lead to economic losses of more than $244 million (extreme risks). The marine transport emergency scenario of a cruise ship grounding and leaking oil into the King George Sound has the largest number of high risks (36%). In addition to the oil spill polluting the marine environment, managing the welfare of ~ 5000 foreign passengers and an oil spill in peak tourist season would be a significant issue.
The animal or plant pests or diseases scenario produced a significant number of high (22%) and medium (31%) risks. Mostly, these relate to significant economic loss, particularly in the agriculture and pastoral sectors. An event of this type would have national and international implications and the impacts would affect a broad spectrum of the agriculture industry for many years.
Natural hazards (bushfire, storm, flood) impact buildings and infrastructure primarily. In particular, damage to bridges, road and rail infrastructure and the disruption to major freight routes from flooding were highlighted as high risks. Extensive building damage may result in people moving away from the district permanently.
Each of the hazard scenarios chosen in the Great Southern were assessed as posing a risk to human life. Earthquake and marine transport emergency scenarios, in particular, could potentially cause more than eight deaths.
