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 Alexandra Hills
Flood
Alexandra Hills faces a moderate risk of flooding, primarily from heavy rainfall events and overflowing of local waterways. The risk is exacerbated by increasing urban density and limited stormwater infrastructure.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Bushfire risk in Alexandra Hills is moderate due to the presence of bushland areas and dry vegetation. Hot, dry conditions during the bushfire season increase the likelihood of fire ignition and spread.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Alexandra Hills experiences a high risk from heatwaves and extreme temperatures. Urban areas retain heat, leading to higher nighttime temperatures and increased heat stress for residents.
Key drivers:
- ·Rising average temperatures
- ·Urban heat island effect
Coastal
Alexandra Hills faces a moderate risk from coastal hazards, including sea level rise and storm surge. Low-lying areas are particularly vulnerable to inundation and erosion.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity

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 Alexandra Hills's Climate Risk Profile
Alexandra Hills, located in the Redland City Council area, is increasingly vulnerable to the impacts of climate change. The suburb's proximity to waterways and bushland elevates its risk profile, particularly concerning flooding and bushfires.
Rising temperatures and more frequent heatwaves pose a significant threat to public health, especially for vulnerable populations. The urban environment exacerbates the heat island effect, leading to higher nighttime temperatures and increased energy demand for cooling.
Coastal risks, including sea level rise and storm surge, also present a challenge for Alexandra Hills. Low-lying areas are susceptible to inundation, potentially impacting property values and infrastructure.
Addressing these climate risks requires a multi-faceted approach, including investments in stormwater infrastructure, bushfire mitigation strategies, and community awareness programs. Residents should take proactive steps to protect their homes and prepare for extreme weather events.
