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.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
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.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Dunalley is likely to experience an increase in the frequency and intensity of heatwaves. This poses a risk to vulnerable populations and infrastructure.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Dunalley is highly vulnerable to coastal hazards due to its low elevation and direct exposure to the coast. Sea level rise and storm surges pose a significant threat.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity

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 Dunalley's Climate Risk Profile
Dunalley, Tasmania, is a coastal town that is particularly vulnerable to the impacts of climate change. Its low-lying location makes it susceptible to sea level rise, storm surges, and coastal erosion. These hazards pose a significant threat to infrastructure, property, and the local economy.
In addition to coastal hazards, Dunalley is also at risk from flooding due to heavy rainfall events. The town's drainage infrastructure may not be adequate to handle increased rainfall intensity, leading to localised flooding and damage.
The risk of bushfires is also a concern, particularly during the dry summer months. The surrounding bushland provides ample fuel for fires, and changes in temperature and rainfall patterns could exacerbate the risk.
Finally, Dunalley is likely to experience an increase in the frequency and intensity of heatwaves. This poses a risk to vulnerable populations, such as the elderly and those with chronic health conditions. It is important for residents to take steps to protect themselves from the heat, such as staying hydrated and seeking air-conditioned environments.
Addressing these climate risks requires a multi-faceted approach, including investments in infrastructure, community education, and adaptation measures. By taking proactive steps, Dunalley can build resilience and protect itself from the worst impacts of climate change.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.

Frequently Asked Questions
What are the main climate change risks for Dunalley?
Dunalley is primarily at risk from coastal hazards, flooding, bushfires, and heatwaves. Sea level rise and storm surges pose a significant threat to coastal infrastructure and property. Increased rainfall intensity can lead to localised flooding. The risk of bushfires is also a concern, particularly during the dry summer months. Finally, Dunalley is likely to experience an increase in the frequency and intensity of heatwaves.
How will sea level rise affect Dunalley?
Sea level rise will exacerbate coastal erosion and increase the risk of inundation from storm surges. Low-lying areas of Dunalley are particularly vulnerable. This could lead to damage to property, infrastructure, and the local economy.
What can I do to prepare for a bushfire?
Prepare a bushfire survival plan, clear vegetation around your home, and ensure you have adequate insurance coverage. Stay informed about fire danger ratings and warnings. If a fire threatens your property, follow the instructions of emergency services.
How can I protect myself during a heatwave?
Stay hydrated, seek air-conditioned environments, and avoid strenuous activity during the hottest part of the day. Check on vulnerable neighbours and family members. Be aware of the symptoms of heatstroke and seek medical attention if necessary.
What is the council doing to address climate change?
The Tasman Council is developing a climate strategy to reduce greenhouse gas emissions and adapt to the impacts of climate change. This includes investments in renewable energy, energy efficiency, and sustainable transportation. The council is also working to improve drainage infrastructure and protect coastal areas.
Where can I find more information about climate change in Tasmania?
You can find more information about climate change in Tasmania on the Tasmanian Government's Climate Change website (https://www.climatechange.tas.gov.au/) and the CSIRO website (https://www.csiro.au/en/research/environmental-impacts/climate-change).
