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 Cornwallis
Flood
Cornwallis is highly susceptible to flooding due to its location on the Hawkesbury River floodplain. The risk is projected to increase with climate change.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Cornwallis faces a moderate bushfire risk due to surrounding vegetation. Hotter, drier conditions are expected to exacerbate this risk.
Key drivers:
- ·Increased temperatures
- ·Drier vegetation
Heat
Cornwallis is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Cornwallis is not directly exposed to coastal hazards, but sea level rise may indirectly affect the region through increased riverine flooding.
Key drivers:
- ·Sea level rise
- ·Storm surge

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 Cornwallis's Climate Risk Profile
Cornwallis is a suburb in the Hawkesbury region of New South Wales, known for its rich agricultural land and proximity to the Hawkesbury River. This low-lying area is particularly vulnerable to flooding, which is expected to worsen with climate change.
The primary climate risk for Cornwallis is flooding. The Hawkesbury River has a history of major floods, and climate change is projected to increase the frequency and intensity of these events. This poses a threat to homes, businesses, and infrastructure in the area.
Bushfire risk is also a concern, as the surrounding vegetation can become dry and flammable during hot, dry periods. Heatwaves are another growing threat, with rising average temperatures and more frequent extreme heat events expected in the future.
While Cornwallis is not directly on the coast, sea level rise can exacerbate riverine flooding, further increasing the risk to the community. Residents should take steps to prepare for these climate risks and protect their properties.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
