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 Sefton
Flood
Sefton faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Climate change is expected to increase rainfall intensity, exacerbating flood risk.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Bushfire risk in Sefton is relatively low due to the urban environment and limited vegetation. However, increased temperatures and drier conditions could elevate the risk.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Sefton is susceptible to heatwaves, with increasing average temperatures posing a significant risk to vulnerable populations. Climate change is projected to increase the frequency and intensity of heat events.
Key drivers:
- ·Increased average temperatures
- ·Urban heat island effect
Coastal
Sefton is not directly exposed to coastal risks due to its inland location. Sea level rise and coastal erosion are not significant concerns for this suburb.
Key drivers:
- ·Distance from the 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 Sefton's Climate Risk Profile
Sefton, located in New South Wales, is increasingly vulnerable to the impacts of climate change. The primary risks include flooding due to increased rainfall intensity and heatwaves resulting from rising average temperatures.
Flooding is a significant concern, with potential for property damage and disruption to daily life. The risk is exacerbated by urban development and potentially inadequate drainage infrastructure. Residents should stay informed about flood warnings and take necessary precautions.
Heatwaves pose a threat to vulnerable populations, particularly the elderly and those with pre-existing health conditions. The urban heat island effect can further amplify temperatures in built-up areas. Access to cooling centers and adequate hydration are crucial during heat events.
While bushfire risk is relatively low, it is essential to maintain awareness and preparedness. Increased temperatures and drier conditions can elevate the risk, especially in areas with nearby vegetation. Residents should adhere to fire safety guidelines and maintain their properties accordingly.
Overall, Sefton needs to focus on adaptation measures to mitigate the impacts of climate change. This includes improving drainage infrastructure, implementing heatwave management plans, and promoting community awareness of climate risks.
