About Cooranbong's Climate Risk Profile

Cooranbong, located in the Lake Macquarie region of New South Wales, is susceptible to a range of climate-related hazards. The primary concerns are flooding, driven by increased rainfall intensity and proximity to waterways, and bushfires, due to the surrounding bushland and projected hotter, drier conditions.

Flooding events can inundate low-lying areas, disrupting transportation and damaging property. The risk is expected to increase as climate change intensifies rainfall patterns. Bushfires pose a significant threat during the fire season, potentially endangering lives and destroying homes. The increasing frequency and intensity of heatwaves will also impact the health and well-being of residents, particularly vulnerable populations.

While Cooranbong is not directly on the coast, sea level rise could indirectly affect the suburb through impacts on nearby coastal communities and potential disruptions to regional infrastructure. It is crucial for residents and local authorities to implement adaptation strategies to mitigate these risks and build resilience to climate change.

These strategies may include improving drainage infrastructure, implementing stricter building codes in flood-prone areas, managing vegetation to reduce bushfire risk, and developing heatwave response plans. Raising community awareness and promoting individual preparedness are also essential components of a comprehensive adaptation approach.
