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 Wallan
Flood
Wallan faces a moderate risk of flooding due to its proximity to waterways and historical flood events. Climate change is expected to increase rainfall intensity, potentially exacerbating flood risk.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Wallan is located in a bushfire-prone area, with significant bushland surrounding the suburb. Hot, dry conditions and strong winds can increase the risk of bushfires.
Key drivers:
- ·Increased frequency of heatwaves
- ·Drier vegetation
Heat
Wallan experiences hot summers, with the potential for heatwaves. Climate change is expected to increase the frequency and intensity of heatwaves, posing a risk to vulnerable populations.
Key drivers:
- ·Increased greenhouse gas emissions
- ·Urban heat island effect
Coastal
Wallan is located inland and does not face a direct risk from coastal hazards such as sea level rise or coastal erosion.
Key drivers:
- ·Distance from the coast

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 Wallan's Climate Risk Profile
Wallan, located in Victoria, is increasingly vulnerable to the impacts of climate change. The primary risks include flooding due to increased rainfall intensity, bushfires exacerbated by hotter and drier conditions, and heatwaves that pose a threat to public health.
Flooding is a concern due to the suburb's proximity to local waterways. Climate change projections indicate an increase in extreme rainfall events, which could overwhelm existing drainage infrastructure and lead to property damage. Residents should be aware of flood risks and take appropriate precautions.
The risk of bushfires is also significant, given the surrounding bushland. Hotter and drier conditions, coupled with strong winds, create an environment conducive to bushfires. Homeowners should maintain their properties and be prepared to evacuate if necessary.
Heatwaves are another growing concern, particularly for vulnerable populations such as the elderly and those with chronic health conditions. Increased frequency and intensity of heatwaves could strain healthcare services and lead to heat-related illnesses. It is important to stay hydrated and seek shelter in cool environments during heatwaves.
While Wallan is not directly exposed to coastal hazards, the broader impacts of climate change, such as disruptions to supply chains and increased demand for resources, could indirectly affect the suburb.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
