Climate Safety Score
5.2/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Willetton faces a moderate risk of flooding, primarily from heavy rainfall events and potential overflow from nearby waterways. The risk is projected to increase slightly due to climate change.
- Bushfire
- Willetton has a notable bushfire risk due to its proximity to bushland areas. Hot, dry summers and strong winds exacerbate the potential for bushfires. Climate change is expected to further increase the frequency and intensity of bushfire events.
- Heat
- Willetton experiences moderately high temperatures during summer, with the potential for heatwaves. Climate change is projected to increase the frequency and intensity of heatwaves, posing a risk to vulnerable populations.
- Storm
- Moderate storm risk — winter storms and occasional severe thunderstorms
- Postcode
- 6155
- Highest high-risk exposure
- 11.7% of land (bushfire)
Climate Safety Analysis
Willetton in Western Australia has an overall climate safety rating of Medium. This multi-hazard assessment combines flood, bushfire, heat, coastal, and storm risk data with climate projections to 2050 from CSIRO and the Bureau of Meteorology.
Key factors affecting Willetton's climate safety include heat, bushfire. Each hazard is assessed independently and combined for an overall picture. Australia has warmed by approximately 1.5 °C since 1910, with flow-on effects to fire weather, extreme rainfall, and heatwave frequency.
Climate safety for property in Willetton is not uniform — it varies by address. Factors such as elevation, distance to waterways, proximity to bushland, and local drainage all influence actual risk at a specific property. Two nearby properties can have materially different risk profiles.
