Learn moreAbout Hervey Bay's Climate Risk Profile
Hervey Bay, located on the Fraser Coast, is increasingly vulnerable to the impacts of climate change. The region's low-lying coastal geography makes it susceptible to flooding from intense rainfall and rising sea levels. Heatwaves are becoming more frequent and severe, posing health risks to vulnerable populations, especially during the summer months.
Bushfire risk is present, particularly in areas adjacent to bushland, although it is generally lower than in other parts of Queensland. Coastal erosion and inundation are also significant concerns, threatening beaches, infrastructure, and ecosystems. Sea level rise and storm surges exacerbate these risks, potentially leading to property damage and displacement.
Climate projections indicate that these risks will intensify in the coming decades. Increased rainfall intensity will likely lead to more frequent and severe flooding events. Higher temperatures will increase the frequency and duration of heatwaves. Sea level rise will continue to erode coastlines and increase the risk of inundation.
Addressing these challenges requires a combination of mitigation and adaptation strategies. Reducing greenhouse gas emissions is crucial to slowing the pace of climate change. Local adaptation measures, such as improving drainage infrastructure, implementing heatwave early warning systems, and protecting coastal ecosystems, can help to reduce the impacts of climate change on Hervey Bay.
