Learn moreAbout George Town's Climate Risk Profile
George Town, located in northern Tasmania, is vulnerable to a range of climate-related hazards. The town's proximity to the Tamar River increases its susceptibility to flooding, especially during periods of heavy rainfall and high tides. Climate change is projected to increase the intensity of rainfall events, further elevating flood risk.
Bushfire risk is also a concern, with surrounding bushland creating a potential source of ignition during dry and windy conditions. Rising temperatures and prolonged droughts can exacerbate bushfire risk, threatening homes and infrastructure.
Heatwaves are becoming more frequent and intense in George Town, posing a health risk to vulnerable populations, such as the elderly and those with pre-existing medical conditions. The urban environment can amplify the effects of heatwaves, creating urban heat islands.
Coastal hazards, including sea level rise and coastal erosion, pose a long-term threat to George Town's coastal areas. Rising sea levels can inundate low-lying areas, damage infrastructure, and erode beaches and shorelines. These changes can impact property values and recreational opportunities.
