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 Dumaresq Island
Flood
Dumaresq Island is susceptible to flooding due to its low-lying geography and proximity to the Manning River. Increased rainfall intensity and rising sea levels are expected to exacerbate flood risk.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Bushfire risk is relatively low due to the island's location and limited vegetation. However, changing climate conditions could increase the potential for bushfires.
Key drivers:
- ·Vegetation dryness
- ·Wind patterns
Heat
Dumaresq Island is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations and infrastructure.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
As an island, Dumaresq Island is highly vulnerable to coastal erosion and sea level rise. These factors threaten infrastructure and ecosystems.
Key drivers:
- ·Sea level rise
- ·Storm surges

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 Dumaresq Island's Climate Risk Profile
Dumaresq Island, located in New South Wales, is particularly vulnerable to the impacts of climate change. Its low-lying geography makes it susceptible to flooding from the Manning River, a risk that is expected to worsen with increased rainfall intensity and rising sea levels. The island also faces threats from coastal erosion and storm surges, which could damage infrastructure and displace communities.
Heatwaves are another significant concern for Dumaresq Island. Rising average temperatures and more frequent heatwaves pose a risk to vulnerable populations, such as the elderly and those with chronic health conditions. The increased heat can also strain energy infrastructure and impact local ecosystems.
While bushfire risk is relatively lower compared to other parts of NSW, changing climate conditions could increase the potential for bushfires on the island. Drier vegetation and stronger winds could create conditions conducive to fire.
Addressing these climate risks requires a coordinated effort from local government, residents, and other stakeholders. Implementing adaptation measures, such as improving drainage infrastructure, protecting coastal areas, and developing heatwave response plans, is crucial to building resilience and protecting the community.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
