About Cathcart's Climate Risk Profile

Cathcart, NSW, is exposed to a range of climate-related risks, including flooding, bushfires, and heatwaves. The suburb's location near waterways increases its vulnerability to flooding during periods of heavy rainfall. Climate change is expected to exacerbate these risks, leading to more frequent and intense extreme weather events.

The bushfire risk in Cathcart is significant due to the proximity of bushland areas. Drier conditions and higher temperatures, driven by climate change, will likely increase the frequency and intensity of bushfires in the region. Residents should take precautions to protect their properties and be prepared to evacuate if necessary.

Heatwaves are also a growing concern for Cathcart. As average temperatures rise, the suburb is expected to experience more frequent and prolonged periods of extreme heat. This poses a particular risk to vulnerable populations, such as the elderly and those with chronic health conditions.

While Cathcart is not directly exposed to coastal risks, the broader impacts of climate change, such as disruptions to supply chains and increased insurance costs, could still affect the suburb. It is important for residents and businesses to take steps to adapt to these changes and build resilience to climate-related risks.
