Is Woronora Dam, NSW Climate Safe? 2026 Assessment
Climate Safety Score
5.2/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Woronora Dam faces a moderate risk of flooding due to its proximity to the Woronora River and surrounding waterways. Heavy rainfall events can lead to increased water levels and potential inundation of low-lying areas.
- Bushfire
- Woronora Dam has a high bushfire risk due to its location surrounded by dense bushland. Dry conditions and strong winds can exacerbate the risk of bushfires spreading rapidly.
- Heat
- Woronora Dam experiences moderate heat risk, with increasing average temperatures and more frequent heatwave events projected in the future.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2508
- Highest high-risk exposure
- 15% of land (bushfire)
Climate Safety Analysis
Woronora Dam in New South Wales has an overall climate safety rating of Medium. This multi-hazard assessment combines flood, bushfire, heat, coastal, and storm risk data with climate projections to 2050 from CSIRO and the Bureau of Meteorology.
Key factors affecting Woronora Dam's climate safety include flood, bushfire. Each hazard is assessed independently and combined for an overall picture. Australia has warmed by approximately 1.5 °C since 1910, with flow-on effects to fire weather, extreme rainfall, and heatwave frequency.
Climate safety for property in Woronora Dam is not uniform — it varies by address. Factors such as elevation, distance to waterways, proximity to bushland, and local drainage all influence actual risk at a specific property. Two nearby properties can have materially different risk profiles.
For a complete property-specific climate safety report for Woronora Dam including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
Woronora Dam (postcode 2508) is tracked in ClimateNest's suburb hazard model, which maps the share of the suburb's land exposed to each hazard at high and moderate levels. The suburb's highest high-risk exposures are bushfire (15% of land in high-risk zones), riverine flood (8.4% of land in high-risk zones), surface flood (5.4% of land in high-risk zones). Exposure is not uniform across Woronora Dam — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
