About Invermay's Climate Risk Profile

Invermay, located near Ballarat, Victoria, is susceptible to several climate-related risks. The suburb's proximity to waterways increases its vulnerability to flooding, particularly during periods of heavy rainfall. Climate change is expected to exacerbate this risk, with projections indicating more intense rainfall events in the future.

Bushfire risk is also a concern for Invermay, given the presence of surrounding grasslands and bushland. Hotter and drier conditions are likely to increase the frequency and severity of bushfires in the region. Residents should be aware of bushfire safety measures and maintain their properties to reduce fuel loads.

Heatwaves pose another significant threat to Invermay, especially for vulnerable populations. As temperatures rise, the risk of heat stress and heatstroke increases. It is important for residents to stay informed about heatwave warnings and take precautions to stay cool and hydrated.

While Invermay is not directly exposed to coastal hazards, the broader impacts of climate change, such as disruptions to supply chains and infrastructure, could still affect the suburb. Adapting to these changes will require a coordinated effort from residents, businesses, and local government.
