About Wynnum's Climate Risk Profile

Wynnum, located in the Northern Territory, is increasingly vulnerable to the impacts of climate change. The region is expected to experience more frequent and intense heatwaves, posing a significant risk to public health, especially for vulnerable populations such as the elderly and those with pre-existing medical conditions.

Bushfire risk is also a major concern for Wynnum. The combination of hotter, drier conditions and increased fuel loads creates a higher likelihood of bushfires, which can threaten lives, property, and infrastructure. Effective bushfire management strategies and community preparedness are crucial for mitigating this risk.

Flooding is another significant hazard for Wynnum, with heavy rainfall events and potential riverine overflow posing a threat to low-lying areas. Climate change is expected to increase the intensity of rainfall, exacerbating flood risk and potentially leading to damage to homes, businesses, and infrastructure.

Coastal hazards, including sea level rise and storm surges, also pose a threat to Wynnum. These hazards can lead to inundation of coastal areas, erosion of shorelines, and damage to coastal infrastructure. Adaptation measures, such as coastal protection works and land-use planning, are necessary to address these risks.
