About Mandalong's Climate Risk Profile

Mandalong, located in the Lake Macquarie region of New South Wales, is susceptible to a range of climate-related hazards. The suburb's proximity to Lake Macquarie and local waterways increases its vulnerability to flooding, especially during periods of heavy rainfall. Climate change is projected to increase rainfall intensity, further elevating the risk of flooding in the area.

Bushfire risk is also a concern for Mandalong, particularly in areas bordering bushland. Hot, dry summers create conditions conducive to bushfires, posing a threat to properties and residents. While the overall bushfire risk is moderate, it is important to maintain vigilance and preparedness.

Heatwaves are becoming more frequent and intense due to climate change, posing a significant health risk to the community. Higher average temperatures can lead to heat stress and other heat-related illnesses, especially among vulnerable populations such as the elderly and those with pre-existing health conditions.

While Mandalong is not directly exposed to coastal hazards, the suburb may experience indirect impacts from sea level rise and storm surges affecting Lake Macquarie. It is important to monitor these changes and implement appropriate adaptation measures to protect the community and infrastructure.
