About Edgeworth's Climate Risk Profile

Edgeworth, located in the Lake Macquarie region of New South Wales, is subject to a range of climate-related risks. The primary concerns are flooding, heatwaves, and bushfires. The suburb's proximity to local waterways makes it vulnerable to flooding, especially during periods of heavy rainfall. Climate change projections indicate an increase in rainfall intensity, which could lead to more frequent and severe flood events.

Heatwaves are another significant risk for Edgeworth. As global temperatures continue to rise, the suburb is expected to experience more frequent and intense heatwaves. This poses a particular threat to vulnerable populations, such as the elderly, children, and those with pre-existing health conditions. The urban heat island effect may also exacerbate the impact of heatwaves in certain areas of the suburb.

Bushfire risk is also a consideration for Edgeworth, given the presence of surrounding bushland. Hotter, drier conditions are expected to increase the frequency and intensity of bushfires, potentially impacting properties located near the urban-bushland interface.

While Edgeworth is not directly exposed to coastal hazards, the broader Lake Macquarie region may experience some indirect impacts from sea level rise and coastal erosion. However, these risks are not considered to be significant for Edgeworth itself.
