Climate Safety Score
5.2/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Unley faces a moderate risk of flooding, primarily from heavy rainfall events and potential stormwater runoff. The risk is influenced by local topography and drainage infrastructure.
- Bushfire
- The bushfire risk in Unley is relatively low due to its urban location. However, proximity to parks and reserves can pose a threat during extreme weather conditions.
- Heat
- Unley experiences a high risk of heatwaves, particularly during the summer months. Urban heat island effect exacerbates the impact of rising temperatures.
- Storm
- Moderate storm risk — occasional severe thunderstorms
- Postcode
- 5061
- Highest high-risk exposure
- 13.2% of land (surface flood)
Climate Safety Analysis
Unley in South 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 Unley's climate safety include heat. 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 Unley 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.
For a complete property-specific climate safety report for Unley including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
Unley (postcode 5061) is tracked in ClimateNest's suburb hazard model, which maps the share of the suburb's land exposed to each hazard at high and moderate levels. The suburb's highest high-risk exposures are surface flood (13.2% of land in high-risk zones), bushfire (9% of land in high-risk zones), riverine flood (3.2% of land in high-risk zones). Exposure is not uniform across Unley — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
