About Tewantin's Climate Risk Profile

Tewantin, located on the Noosa River, is a suburb that faces a range of climate-related risks. The primary concerns are flooding, bushfires, heatwaves, and coastal hazards such as sea level rise and storm surge.

Flooding is a significant risk due to the suburb's proximity to the river and low-lying areas. Increased rainfall intensity, driven by climate change, could lead to more frequent and severe flood events. This can damage property, disrupt infrastructure, and pose risks to human safety.

Bushfire risk is also a concern, particularly in areas bordering bushland. Drier conditions and higher temperatures can increase the likelihood of bushfires, threatening homes and ecosystems. Residents need to be aware of bushfire safety measures and maintain their properties accordingly.

Heatwaves are expected to become more frequent and intense, posing health risks to vulnerable populations, such as the elderly and those with chronic illnesses. The urban heat island effect can exacerbate these risks in built-up areas.

Coastal hazards, including sea level rise and storm surge, pose a threat to low-lying areas near the Noosa River. These hazards can cause erosion, inundation, and damage to infrastructure. Planning for coastal adaptation is essential to protect the community and its assets.
