Hazard Breakdown
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
Wind
Moderate wind risk — cold fronts and gusty winds
Storm
Moderate storm risk — severe thunderstorms
Social
Moderate social stability
Energy
Moderate energy costs — heating and cooling needs

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.
