Is Bunbury, WA Climate Safe? 2026 Assessment
Climate Safety Score
5.8/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Bunbury faces a moderate risk of flooding due to its low-lying coastal location and proximity to the Preston River and Leschenault Estuary. Increased rainfall intensity and sea level rise are expected to exacerbate these risks.
- Bushfire
- Bunbury has a moderate bushfire risk due to the presence of nearby bushland and dry vegetation during the summer months. Changes in temperature and rainfall patterns could increase the frequency and intensity of bushfires.
- Heat
- Bunbury is projected to experience more frequent and intense heatwaves, particularly during the summer months. This poses a risk to vulnerable populations, such as the elderly and those with chronic health conditions.
- Storm
- Moderate storm risk — winter storms and occasional severe thunderstorms
- Postcode
- 6230
- Highest high-risk exposure
- 20.4% of land (bushfire)
