WA has a history of floods, often causing widespread impact. Floods are a natural phenomenon. After heavy rainfall, rivers, creeks and catchments may be unable to cope with water volumes and overflow causing flash flooding or slower rising riverine flooding, which is the most common cause of floods in Australia.
Industry and communities rely heavily upon natural gas. A gas supply disruption threatened WA in 2008 when an explosion occurred at the Varanus offshore plant that supplies over 30% of the state’s gas needs, including large mining companies.
Marine oil pollution can have severe impacts on the environment and economy, with the response phase lasting months and the recovery phase sometimes lasting for decades. Marine oil pollution events in WA include the 2009 Montara oil spill that lasted for 76 days with about 60 tonnes of oil entering the environment each day.

Marine transport emergencies can threaten lives and have significant consequences for the economy and environment. Marine transport emergencies in Australian waters include the 2007 Pasha Bulker incident which grounded the ship for almost a month.
Sinking, lost and distressed vessels and aircraft, along with marine searches, occur frequently off our coastline. Australia has a search-and-rescue service that covers 52.8 million square kilometres of the Indian, Pacific and Southern oceans. Plans are in place to coordinate efforts where Commonwealth and state responsibilities intersect.
