About Gundagai's Climate Risk Profile

Gundagai, located in the Riverina region of New South Wales, is historically vulnerable to flooding due to its proximity to the Murrumbidgee River. Climate change is projected to increase the intensity and frequency of heavy rainfall events, leading to a higher risk of riverine flooding. This poses a significant threat to properties and infrastructure in low-lying areas.

The surrounding bushland also makes Gundagai susceptible to bushfires. Rising temperatures and drier conditions are expected to lengthen the bushfire season and increase the severity of fires. Residents need to be prepared for potential evacuations and property damage.

Heatwaves are another growing concern for Gundagai. As average temperatures rise, the frequency and intensity of heatwaves will increase, posing health risks, especially for the elderly and those with pre-existing conditions.

While coastal risks are minimal due to its inland location, Gundagai must focus on mitigating flood, bushfire, and heatwave risks to protect its community and economy. Adaptation measures and community awareness are crucial for building resilience to climate change impacts.
