Flood
Dalyston has a moderate flood risk, primarily associated with localised heavy rainfall events and potential overland flow paths. While not directly on a major river, the topography can channel water.
Key drivers:
- ·Increased intensity of rainfall events
- ·Urbanisation and increased impervious surfaces
Bushfire
Dalyston is situated in a bushfire-prone area, with significant vegetation surrounding the township. The risk is influenced by fuel loads, weather conditions, and proximity to grasslands and forests.
Key drivers:
- ·Increased frequency and intensity of heatwaves
- ·Drier vegetation conditions
Heat
The region experiences hot summers, and Dalyston is susceptible to heatwaves. Factors contributing to heat risk include average maximum temperatures and the potential for prolonged periods of extreme heat.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of extreme heat days
Coastal
Dalyston is located inland and is not directly exposed to coastal erosion or inundation risks from sea-level rise.

Detailed Hazard Analysis
heat Risk
The region experiences hot summers, and Dalyston is susceptible to heatwaves. Factors contributing to heat risk include average maximum temperatures and the potential for prolonged periods of extreme heat.
Primary Drivers
- ·Rising average temperatures
- ·Increased frequency of extreme heat days
- ·Urban heat island effect (though less pronounced in smaller towns)
flood Risk
Dalyston has a moderate flood risk, primarily associated with localised heavy rainfall events and potential overland flow paths. While not directly on a major river, the topography can channel water.
Primary Drivers
- ·Increased intensity of rainfall events
- ·Urbanisation and increased impervious surfaces
- ·Changes in land use upstream
coastal Risk
Dalyston is located inland and is not directly exposed to coastal erosion or inundation risks from sea-level rise.
Data sourcebushfire Risk
Dalyston is situated in a bushfire-prone area, with significant vegetation surrounding the township. The risk is influenced by fuel loads, weather conditions, and proximity to grasslands and forests.
Primary Drivers
- ·Increased frequency and intensity of heatwaves
- ·Drier vegetation conditions
- ·Expansion of urban interface into bushland
What This Means for Property Owners
Insurance Outlook
Increasing premiums and potential for higher excess due to bushfire and flood risks.
Price Impact
Potential for negative impact on property values in high-risk zones, particularly for properties with inadequate mitigation measures.
Buyer Checklist
- 1.Review current and future flood risk maps.
- 2.Assess bushfire attack level (BAL) rating and property defensibility.
- 3.Check proximity to vegetation and potential fuel sources.
- 4.Investigate local emergency services and evacuation plans.
- 5.Understand insurance availability and cost implications.
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 Dalyston's Climate Risk Profile
Dalyston, a small rural township in Victoria's Bass Coast Shire, is situated in a landscape that presents a complex mix of climate-related risks. While not directly on the coast, its proximity to significant bushland areas places it within a high bushfire risk zone. The surrounding topography and potential for intense rainfall events also contribute to a moderate flood risk, primarily from overland flows and localised creek flooding.
The increasing frequency and intensity of heatwaves, a statewide trend, also impact Dalyston. As average temperatures rise and extreme heat days become more common, the community faces heightened risks associated with heat stress, particularly for vulnerable populations and during the summer months. While coastal inundation and erosion are not direct threats due to its inland location, the broader regional climate shifts influence the environmental conditions that exacerbate bushfire and flood risks.
Understanding these risks is crucial for the resilience of Dalyston. The community's preparedness for bushfire events, including effective evacuation plans and property protection measures, is paramount. Similarly, managing localised flood risks requires attention to drainage infrastructure and land use planning to mitigate the impact of heavy rainfall. The long-term trend of rising temperatures necessitates strategies to cope with increased heat exposure.
Climate change projections indicate an intensification of these hazards. Future scenarios suggest more extreme weather events, including more severe bushfires, heavier rainfall leading to increased flood potential, and more frequent and intense heatwaves. These projections underscore the need for proactive adaptation and mitigation strategies to safeguard the community, its infrastructure, and its natural environment.

Frequently Asked Questions
What is the main bushfire risk for Dalyston residents?
The main bushfire risk stems from the surrounding grasslands and bushland. During hot, dry, and windy conditions, fires can spread rapidly towards the township. Residents should have a bushfire survival plan and monitor CFA advice.
Does Dalyston experience significant flooding?
Dalyston is not typically subject to major riverine flooding. However, intense rainfall can cause localised flooding and overland flow issues, particularly in low-lying areas or where drainage is inadequate. Check the Bass Coast Shire flood overlay maps for specific details.
How will climate change affect heatwaves in Dalyston?
Climate change is projected to increase the frequency, intensity, and duration of heatwaves in Dalyston. This means more days above 35°C and a greater risk of heat-related illnesses.
What are the recommended actions for property owners regarding bushfire risk?
Property owners should create and maintain a defendable space around their homes, clear gutters and roofs of debris, and ensure they have appropriate fire-resistant building materials where possible. Regularly review your bushfire survival plan.
Is Dalyston affected by sea-level rise?
No, Dalyston is located sufficiently inland and at an elevation that it is not directly exposed to risks from sea-level rise or coastal erosion.
Where can I find more information about local climate risks?
The Bass Coast Shire Council website provides information on planning schemes, flood maps, and environmental strategies. The Country Fire Authority (CFA) and the Bureau of Meteorology (BOM) are key resources for bushfire and weather information.
