The State Risk Project began in 2013 with the assessment of credible worst case and near worst case scenarios for seven sudden onset natural hazards. These were bushfire, cyclone, earthquake, flood, heatwave, storm and tsunami. These seven hazards were re-assessed in 2017 using the 2015 National Emergency Risk Assessment Guidelines (NERAG) and are summarised in the report Western Australia's Natural Hazards Risk Profile 2017.

As of mid-2018, risk assessments for 26 of the 27 identified hazards (terrorism has been excluded in consultation with the WA Police Force) have been completed at the state-level. In addition, the potential hazard of telecommunication disruption was assessed and three actual events (Cyclone Christine, the Parkerville Fire and the Kununurra Floods) were reviewed using the same criteria.

Analysis of the hazards assessed to date reveals no risk statements presenting as extreme risks. However 15.7% presented a high risk, while 29.7% presented a medium risk. The remaining 54.6% of statements were assessed as low risks. Further information on the criteria used to determine risk level can be found in the Western Australian Emergency Risk Management Procedure.
