Hazard Breakdown
Climate Hazard Breakdown for Edgeworth
Flood
Edgeworth faces a moderate risk of flooding due to its proximity to local waterways and low-lying areas. Climate change is expected to increase rainfall intensity, exacerbating flood risk.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Edgeworth has a moderate bushfire risk due to the presence of surrounding bushland. Hotter, drier conditions are expected to increase the frequency and intensity of bushfires.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Edgeworth is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations, such as the elderly and those with chronic health conditions.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Edgeworth is not directly exposed to coastal hazards. Sea level rise and coastal erosion are not significant concerns for this suburb.
Key drivers:
- ·Distance from the coast
Wind
Moderate wind risk — East Coast Lows and gust fronts
Storm
Moderate storm risk — severe thunderstorms and hail
Social
Moderate social stability — mixed urban density
Energy
Moderate energy costs — climate-driven cooling demand

Historical Climate Events
Major flooding occurred in the Hunter region, impacting Edgeworth and surrounding areas. Several homes were inundated, and roads were closed.
SourceBushfires burned in the Lake Macquarie area, threatening homes in Edgeworth and other suburbs. Firefighters worked to contain the blazes and protect properties.
SourceA severe storm caused widespread damage in the Hunter region, including Edgeworth. Heavy rain, strong winds, and flash flooding were reported.
SourceEdgeworth experienced a prolonged heatwave with temperatures exceeding 40 degrees Celsius for several days. This put strain on the electricity grid and caused health concerns for vulnerable residents.

Learn moreAbout 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.
