Learn moreAbout Nerrina's Climate Risk Profile
Nerrina, located near Ballarat, Victoria, is vulnerable to several climate-related hazards. The suburb's proximity to bushland increases its risk of bushfires, particularly during hot and dry conditions. Climate change projections indicate a higher frequency of extreme heat days and prolonged drought periods, further elevating the bushfire threat.
Flooding is another concern for Nerrina, with heavy rainfall events capable of causing flash flooding in low-lying areas. The increasing intensity of rainfall due to climate change could overwhelm existing drainage infrastructure, leading to more frequent and severe flooding.
Heatwaves are becoming more common and intense in Victoria, posing a significant risk to vulnerable populations in Nerrina. The elderly, young children, and individuals with pre-existing health conditions are particularly susceptible to heat stress during these events.
While Nerrina is not directly exposed to coastal hazards, the broader impacts of climate change, such as disruptions to supply chains and economic activity, could indirectly affect the suburb. Residents and local authorities need to implement adaptation measures to mitigate these risks and build resilience to climate change.
