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 Wantirna
Flood
Wantirna faces a moderate risk of flooding, primarily from heavy rainfall events and local creek overflows. Development and urbanization have increased runoff, exacerbating the risk.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
The bushfire risk in Wantirna is moderate due to its proximity to bushland areas. Hot, dry summers and strong winds can increase the likelihood of bushfires.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Wantirna is experiencing an increase in the frequency and intensity of heatwaves. This poses a significant risk to vulnerable populations, such as the elderly and those with chronic health conditions.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Wantirna is located inland and has a very low risk of coastal hazards such as sea level rise and 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 Wantirna's Climate Risk Profile
Wantirna, located in Melbourne's eastern suburbs, is increasingly vulnerable to the impacts of climate change. The primary risks include more frequent and intense heatwaves, increased flooding due to heavy rainfall, and a moderate bushfire risk due to proximity to bushland.
The increasing frequency and intensity of heatwaves pose a significant threat to the health and well-being of Wantirna residents, particularly the elderly and those with pre-existing health conditions. Urban development and the urban heat island effect exacerbate this risk.
Flooding is another concern, with heavy rainfall events leading to local creek overflows and stormwater drainage issues. Development has increased the amount of impervious surfaces, leading to increased runoff and a higher risk of flooding.
While the coastal risk is low, the suburb needs to focus on mitigating heat and flood risks. Residents should stay informed about emergency warnings and take steps to prepare their homes and families for extreme weather events.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
