About Bilgola Plateau's Climate Risk Profile

Bilgola Plateau, located in New South Wales, is susceptible to several climate change impacts. The suburb's proximity to bushland elevates the risk of bushfires, particularly during dry and windy conditions. Climate change is expected to increase the frequency and intensity of these events, posing a significant threat to property and life.

The suburb also faces coastal risks due to its location near the ocean. Sea level rise and increased storm surges can lead to coastal erosion and inundation, impacting infrastructure and property values. These risks are projected to worsen as global temperatures continue to rise.

Furthermore, Bilgola Plateau is vulnerable to flooding from heavy rainfall events. Climate change is expected to increase rainfall intensity, potentially leading to more frequent and severe flooding. This can disrupt transportation, damage property, and pose risks to public health.

Rising temperatures and more frequent heatwaves also pose a threat to Bilgola Plateau. Vulnerable populations, such as the elderly and those with chronic health conditions, are particularly at risk. The urban heat island effect can exacerbate these impacts, especially in densely populated areas. Adaptation measures are crucial to mitigate these risks and protect the community.
