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 Bonnet Bay
Flood
Bonnet Bay is located near the Woronora River and has some areas susceptible to flooding, particularly during heavy rainfall events and king tides. Climate change is expected to increase the frequency and intensity of extreme rainfall, exacerbating flood risk.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Bonnet Bay is adjacent to bushland, making it vulnerable to bushfires, especially during hot, dry, and windy conditions. Climate change is projected to increase the frequency and severity of bushfire weather, leading to a higher risk of bushfires.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Bonnet Bay experiences hot summers, and climate change is expected to increase the frequency and intensity of heatwaves. This can pose a risk to vulnerable populations, such as the elderly and those with chronic health conditions.
Key drivers:
- ·Increased temperatures
- ·More frequent heatwaves
Coastal
Bonnet Bay is located near the coast and Woronora River, making it susceptible to coastal erosion and inundation from sea level rise and storm surges. Climate change is expected to exacerbate these risks.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity

What This Means for Property Owners
Insurance Outlook
Insurance premiums are likely to increase in response to increased climate risks, particularly for properties in flood-prone or bushfire-prone areas.
Price Impact
Properties in high-risk areas may experience a decrease in value as climate risks become more apparent.
Buyer Checklist
- 1.Check flood maps and bushfire-prone area designations.
- 2.Assess the property's vulnerability to heatwaves.
- 3.Review insurance options and potential premium increases.
- 4.Consider the long-term impacts of climate change on property value.
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 Bonnet Bay's Climate Risk Profile
Bonnet Bay, located in the Sutherland Shire, is a suburb that will experience the growing impacts of climate change. The primary risks include increased flooding due to more intense rainfall and rising sea levels, heightened bushfire danger from hotter and drier conditions, more frequent and severe heatwaves, and coastal erosion and inundation.
Flooding is a significant concern for properties near the Woronora River. Climate change is projected to increase rainfall intensity, leading to more frequent and severe flooding events. Sea level rise will further exacerbate this risk, increasing the potential for coastal inundation.
The suburb's proximity to bushland also makes it vulnerable to bushfires. As temperatures rise and conditions become drier, the risk of bushfires will increase. Residents need to be prepared for potential evacuations and property damage.
Heatwaves are expected to become more frequent and intense, posing a health risk to vulnerable populations. It is important to have strategies in place to cope with extreme heat, such as staying hydrated and seeking air-conditioned environments.
Coastal erosion and inundation are also concerns, particularly for properties located close to the Woronora River. Sea level rise and storm surges will increase the risk of damage to coastal infrastructure and properties.
