Is South Perth, WA Climate Safe? 2026 Assessment
Climate Safety Score
5.5/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- South Perth faces a moderate risk of flooding, primarily from riverine sources and intense rainfall events. The Swan River poses a constant threat, and localized flooding can occur due to inadequate drainage.
- Bushfire
- Bushfire risk in South Perth is relatively low due to its urbanized environment and distance from large bushland areas. However, parks and reserves can still pose a localized risk.
- Heat
- South Perth experiences a high heat risk, with increasing average temperatures and more frequent heatwave events. Urban heat island effect exacerbates the problem.
- Storm
- Moderate storm risk — winter storms and occasional severe thunderstorms
- Postcode
- 6151
- Highest high-risk exposure
- 12% of land (bushfire)
Climate Safety Analysis
South Perth 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 South Perth's climate safety include heat, flood, coastal. 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 South Perth 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.
