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 St Huberts Island
Flood
St Huberts Island is susceptible to flooding due to its low-lying coastal location and proximity to Brisbane Water. Sea level rise and increased rainfall intensity are expected to exacerbate flood risk.
Key drivers:
- ·Sea level rise
- ·Increased rainfall intensity
Bushfire
Bushfire risk is relatively low due to the island's limited vegetation and surrounding waterways, which act as natural firebreaks. However, dry conditions and strong winds can still pose a threat.
Key drivers:
- ·Dry conditions
- ·Strong winds
Heat
St Huberts Island experiences moderate heat risk, with increasing average temperatures and more frequent heatwaves projected. This can impact vulnerable populations and infrastructure.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
As an island, St Huberts Island is highly vulnerable to coastal erosion and sea level rise. This poses a significant threat to properties, infrastructure, and the natural environment.
Key drivers:
- ·Sea level rise
- ·Coastal erosion

Detailed Hazard Analysis
heat Risk
St Huberts Island experiences moderate heat risk, with increasing average temperatures and more frequent heatwaves projected. This can impact vulnerable populations and infrastructure.
Primary Drivers
- ·Rising average temperatures
- ·Increased frequency of heatwaves
- ·Urban heat island effect
flood Risk
St Huberts Island is susceptible to flooding due to its low-lying coastal location and proximity to Brisbane Water. Sea level rise and increased rainfall intensity are expected to exacerbate flood risk.
Primary Drivers
- ·Sea level rise
- ·Increased rainfall intensity
- ·Storm surge
coastal Risk
As an island, St Huberts Island is highly vulnerable to coastal erosion and sea level rise. This poses a significant threat to properties, infrastructure, and the natural environment.
Primary Drivers
- ·Sea level rise
- ·Coastal erosion
- ·Storm surge
bushfire Risk
Bushfire risk is relatively low due to the island's limited vegetation and surrounding waterways, which act as natural firebreaks. However, dry conditions and strong winds can still pose a threat.
Primary Drivers
- ·Dry conditions
- ·Strong winds
- ·Vegetation density
What This Means for Property Owners
Insurance Outlook
Insurance premiums are likely to increase due to the rising risk of flooding and coastal erosion.
Price Impact
Properties vulnerable to flooding and coastal erosion may experience a decrease in value.
Buyer Checklist
- 1.Check flood maps and coastal erosion risk assessments.
- 2.Assess the property's vulnerability to flooding and coastal erosion.
- 3.Obtain insurance quotes and understand policy coverage.
- 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 St Huberts Island's Climate Risk Profile
St Huberts Island, located in Brisbane Water, is particularly vulnerable to the impacts of climate change. The island's low-lying topography makes it susceptible to flooding from increased rainfall and rising sea levels. Coastal erosion is also a significant concern, threatening properties and infrastructure along the shoreline.
Rising temperatures are expected to lead to more frequent and intense heatwaves, posing health risks to vulnerable residents. Changes in rainfall patterns could also affect water availability and the local ecosystem. While bushfire risk is relatively low, it cannot be entirely discounted, especially during prolonged dry periods.
The Central Coast Council is actively working on climate adaptation strategies to mitigate these risks. These strategies include improving drainage infrastructure, implementing coastal protection measures, and promoting community awareness of climate change impacts.
Homeowners should consider taking steps to protect their properties from flooding and coastal erosion. This may include raising homes, installing flood barriers, and reinforcing seawalls. It is also important to have an emergency plan in place and to stay informed about weather warnings and evacuation procedures.
