Overall Risk Score
Hazard Breakdown
Flood, bushfire, heat, coastal and storm exposure are all assessed in this area. The score that matters is the property's own: a ClimateNest report scores the address across eight hazards, with insurance and value projections to 2050.
Climate Hazard Breakdown for Unley
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.
Key drivers:
- ·Increased rainfall intensity
- ·Urbanisation
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.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Unley experiences a high risk of heatwaves, particularly during the summer months. Urban heat island effect exacerbates the impact of rising temperatures.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Unley is located inland and does not face a direct risk from coastal hazards such as sea level rise or coastal erosion.
Key drivers:
- ·Distance from coast

How the region's climate is projected to change
Regional projections, not a forecast for this street. Figures are from the WA Department of Water and Environmental Regulation's climate projections for the South Western Flatlands region, which draws on CSIRO and Bureau of Meteorology modelling.
Temperature
+0.5 to 1.1°C by 2030
Above the 1986–2005 climate, on all emissions scenarios. By 2090, 1.2 to 2.0°C under intermediate emissions or 2.6 to 4.0°C under high emissions.
Rainfall
Winter rain down up to 15% by 2030
The South West has been drying since 1970, and the decline has been larger than anywhere else in Australia. Heavy rainfall events are projected to become more intense even as totals fall.
Fire weather
Harsher, magnitude uncertain
High confidence that fire weather becomes harsher, low confidence in the size of the change, because it depends heavily on summer rainfall.
Sea level
+0.12 m by 2030
At the Fremantle gauge, range 0.07 to 0.16 m. Very high confidence that sea levels continue to rise through the century.

Learn moreAbout Unley's Climate Risk Profile
Unley, South Australia, is primarily threatened by increasing heatwave intensity and potential flooding. The urban environment exacerbates the impact of rising temperatures, creating a significant risk for vulnerable populations. Changes in rainfall patterns could lead to more frequent and intense flooding events, impacting infrastructure and property.
While the risk of bushfire is relatively low due to the suburb's urban location, it is not entirely absent. Parks and reserves in and around Unley could pose a risk during extreme weather conditions. Coastal risks are minimal due to Unley's inland location.
Climate change projections indicate a worsening of these risks in the coming decades. Heatwaves are expected to become more frequent and intense, while rainfall patterns may become more erratic, increasing the likelihood of flooding. Adaptation measures are crucial to mitigate these impacts and protect the community.
Addressing these climate risks requires a multi-faceted approach, including urban greening initiatives to reduce the urban heat island effect, upgrades to stormwater infrastructure to manage increased rainfall, and community awareness programs to prepare residents for extreme weather events. Collaboration between local government, residents, and other stakeholders is essential to build a climate-resilient Unley.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
