About Cammeray's Climate Risk Profile

Cammeray, located on the Lower North Shore of Sydney, faces a range of climate change impacts. The suburb's proximity to Sydney Harbour makes it vulnerable to sea level rise and storm surges, increasing the risk of coastal inundation and erosion. More intense rainfall events could also lead to more frequent and severe flooding, particularly in low-lying areas.

Rising temperatures and more frequent heatwaves pose a significant threat to the health and well-being of Cammeray residents, especially the elderly and those with pre-existing health conditions. The urban heat island effect, caused by the concentration of buildings and paved surfaces, can further amplify temperatures in the suburb.

While the risk of bushfire is relatively low compared to other parts of NSW, increased temperatures and drier conditions could elevate the risk, particularly in areas bordering bushland. Residents should be aware of the potential for bushfires and take steps to prepare their properties.

Addressing these climate change risks requires a coordinated effort from local government, residents, and businesses. Implementing adaptation measures, such as improving drainage infrastructure, increasing green spaces, and promoting energy efficiency, can help to reduce the suburb's vulnerability to climate change impacts. Residents should also stay informed about the latest climate projections and take steps to prepare for extreme weather events.
