Learn moreAbout Mallacoota's Climate Risk Profile
Mallacoota, located in East Gippsland, Victoria, is highly vulnerable to the impacts of climate change. The region's coastal location and surrounding bushland make it susceptible to a range of hazards, including bushfires, flooding, heatwaves, and coastal erosion.
Bushfire risk is a major concern for Mallacoota, as the area has experienced devastating bushfires in the past, including the 2019-2020 Black Summer bushfires. Rising temperatures and drier conditions are expected to increase the frequency and intensity of bushfires in the future.
Flooding is another significant risk, with the potential for both flash flooding from intense rainfall events and riverine flooding from nearby waterways. Sea level rise and storm surges exacerbate the risk of coastal inundation, threatening low-lying areas and infrastructure.
Heatwaves are becoming more frequent and intense, posing a threat to public health, particularly for vulnerable populations such as the elderly and those with chronic health conditions. The increasing average temperatures also contribute to drier conditions, further increasing the risk of bushfires.
Coastal erosion is an ongoing issue, with sea level rise threatening to erode beaches and coastal infrastructure. The combined effects of these climate change impacts pose a significant challenge to the community and the local economy.
