About Eighteen Mile's Climate Risk Profile

Eighteen Mile is a suburb in New South Wales that is increasingly vulnerable to the impacts of climate change. The primary risks include more frequent and intense heatwaves, increased flooding due to heavy rainfall, and a moderate risk of bushfires.

The rising temperatures pose a significant threat to the health and well-being of residents, especially the elderly and those with pre-existing conditions. The urban heat island effect can exacerbate these conditions, making the suburb even hotter than surrounding areas.

Flooding is another major concern, with the potential for heavy rainfall events to cause significant damage to property and infrastructure. The proximity to waterways increases the risk of riverine flooding, while poor drainage can lead to flash flooding in urban areas.

Bushfire risk is moderate, with surrounding vegetation providing fuel for potential fires. Drier conditions and higher temperatures can increase the likelihood of bushfires, posing a threat to homes and lives.

Coastal risks, including sea level rise and coastal erosion, are also present, though potentially less immediate than other threats. Residents should stay informed about these risks and take steps to prepare for potential impacts.
