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 Penneshaw
Flood
Penneshaw faces a moderate risk of flooding, primarily from heavy rainfall events and potential coastal inundation. The risk is influenced by its coastal location and low-lying areas.
Key drivers:
- ·Sea level rise
- ·Increased rainfall intensity
Bushfire
The area around Penneshaw has a notable bushfire risk due to the presence of surrounding scrubland and forests. Hot, dry summers increase the likelihood of bushfires.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Penneshaw experiences moderate heat risk, with increasing average temperatures and more frequent heatwave events projected. This poses challenges for vulnerable populations and infrastructure.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect (minimal in Penneshaw, but relevant)
Coastal
Penneshaw faces a high coastal risk due to its location on the coast. Sea level rise and increased storm intensity threaten coastal erosion and inundation of low-lying areas.
Key drivers:
- ·Sea level rise
- ·Increased storm surge

What This Means for Property Owners
Insurance Outlook
Insurance premiums are likely to increase due to climate risks.
Price Impact
Properties in high-risk areas may experience price reductions.
Buyer Checklist
- 1.Check flood maps and bushfire prone area designations.
- 2.Assess the property's vulnerability to coastal erosion.
- 3.Inquire about insurance costs and coverage.
- 4.Consider the long-term climate risks when making a purchase decision.
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 Penneshaw's Climate Risk Profile
Penneshaw, located on Kangaroo Island, is increasingly vulnerable to the impacts of climate change. The primary risks include coastal inundation due to sea level rise, increased bushfire frequency and intensity, and more frequent heatwave events.
The coastal risk is particularly pronounced, with projections indicating significant sea level rise by 2050. This will likely lead to increased erosion and inundation of low-lying coastal areas, impacting infrastructure and property.
Bushfire risk is also a major concern, as hotter and drier conditions create a more conducive environment for fires to start and spread rapidly. The surrounding scrubland and forests contribute to this risk.
Heatwaves are expected to become more frequent and intense, posing health risks to vulnerable populations, especially the elderly and those with pre-existing conditions. Infrastructure may also be strained during extreme heat events.
Addressing these climate risks requires a combination of mitigation and adaptation strategies, including reducing greenhouse gas emissions, implementing coastal protection measures, improving bushfire preparedness, and enhancing community resilience to heatwaves.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
