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 Mitchells Island
Flood
Mitchells Island is at moderate risk of flooding due to its low-lying coastal location and proximity to waterways. Increased rainfall intensity and sea level rise are expected to exacerbate this risk.
Key drivers:
- ·Sea level rise
- ·Increased rainfall intensity
Bushfire
The risk of bushfire in Mitchells Island is relatively low due to the cleared land and coastal environment. However, surrounding bushland areas pose a potential threat, especially during dry periods.
Key drivers:
- ·Proximity to bushland
- ·Dry conditions
Heat
Mitchells Island experiences high temperatures during summer, with the risk of heatwaves increasing due to climate change. This poses a significant threat to vulnerable populations.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Mitchells Island is vulnerable to coastal erosion and inundation due to sea level rise. This poses a threat to infrastructure and property located near the coastline.
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 Mitchells Island's Climate Risk Profile
Mitchells Island, located in New South Wales, is susceptible to a range of climate-related hazards. Its coastal location makes it particularly vulnerable to sea level rise and storm surges, which can lead to coastal erosion and inundation of low-lying areas.
Increased rainfall intensity is also a concern, as it can exacerbate flooding risks. The combination of rising sea levels and more frequent heavy rainfall events poses a significant threat to infrastructure and property in the area.
Heatwaves are another growing concern, with average temperatures expected to rise in the coming decades. This can lead to heat stress and other health problems, particularly for vulnerable populations such as the elderly and those with chronic illnesses.
While bushfire risk is relatively low compared to other parts of NSW, it is still a factor to consider, especially during dry periods. Residents should be aware of the potential for bushfires and take steps to protect their homes and properties.
