Climate Safety Score
5.8Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Dunalley faces a moderate risk of flooding due to its low-lying coastal location and proximity to waterways. Heavy rainfall events can lead to localised flooding.
- Bushfire
- The risk of bushfire in Dunalley is moderate, given the surrounding bushland and dry conditions during summer months. Changes in temperature and rainfall patterns could exacerbate this risk.
- Heat
- Dunalley is likely to experience an increase in the frequency and intensity of heatwaves. This poses a risk to vulnerable populations and infrastructure.
- Storm
- Moderate storm risk — westerly wind storms and occasional severe weather

Climate Safety Analysis
Dunalley in Tasmania has an overall climate safety rating of Medium. This multi-hazard assessment combines flood, bushfire, heat, coastal, and storm risk data with climate projections to 2050 from CSIRO and the Bureau of Meteorology.
Key factors affecting Dunalley's climate safety include heat, flood, coastal. Each hazard is assessed independently and combined for an overall picture. Australia has warmed by approximately 1.5 °C since 1910, with flow-on effects to fire weather, extreme rainfall, and heatwave frequency.
Climate safety for property in Dunalley is not uniform — it varies by address. Factors such as elevation, distance to waterways, proximity to bushland, and local drainage all influence actual risk at a specific property. Two nearby properties can have materially different risk profiles.
For a complete property-specific climate safety report for Dunalley including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
ClimateNest assesses hazards at the address rather than the suburb, because exposure varies street by street within Dunalley. An address-level check is what tells you about a specific property before you buy, sell or insure it.

Which climate hazard poses the biggest risk in Dunalley?
The dominant hazard for Dunalley depends on geography and local environment. Proximity to waterways elevates flood risk, while proximity to bushland increases bushfire risk. ClimateNest's multi-hazard analysis identifies the highest-risk hazards for any specific address.
How does Dunalley compare to nearby suburbs for climate safety?
Nearby suburbs may have different climate risk profiles depending on elevation, vegetation cover, drainage patterns, and land use. ClimateNest allows comparison of climate safety scores across Tasmania suburbs.
Should I be concerned about buying property in Dunalley?
Climate risk should be one factor in your decision, alongside price, location, and amenity. An informed buyer understands the specific risks at a property address and factors insurance costs and climate projections into their assessment of long-term value.
