About Mount Gambier's Climate Risk Profile

Mount Gambier, located in South Australia, is subject to a range of climate-related risks. Flooding is a concern due to heavy rainfall and stormwater runoff, particularly in low-lying areas. Bushfires pose a threat due to the surrounding bushland, especially during dry seasons.

Heatwaves are becoming more frequent and intense, impacting vulnerable populations and infrastructure. While Mount Gambier is not directly exposed to coastal risks, the broader region may experience indirect effects from sea level rise and coastal erosion.

Climate change projections indicate an increase in the frequency and intensity of extreme weather events. This includes more severe heatwaves, heavier rainfall, and prolonged dry periods, potentially exacerbating bushfire risks.

Adaptation measures are crucial to mitigate these risks. These include improving stormwater drainage, implementing bushfire management strategies, and developing heatwave response plans. Community awareness and preparedness are also essential to building resilience.
