- Medium
- Flood
- Kurnell faces a moderate risk of flooding due to its low-lying coastal location and proximity to waterways. Increased rainfall intensity and sea level rise are expected to exacerbate this risk.
- Bushfire
- Kurnell has a moderate bushfire risk due to its proximity to the Royal National Park. Hot, dry conditions and strong winds can increase the likelihood of bushfires.
- Heat
- Kurnell is expected to experience more frequent and intense heatwaves in the future. This will increase the risk of heatstroke and other heat-related illnesses, particularly for vulnerable populations.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2231
- Highest high-risk exposure
- 9.2% of land (surface flood)
Climate Safety Analysis
Kurnell 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 Kurnell's climate safety include heat, flood. 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 Kurnell 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 Kurnell including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
Kurnell (postcode 2231) 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 surface flood (9.2% of land in high-risk zones), bushfire (8.7% of land in high-risk zones), riverine flood (5.6% of land in high-risk zones). Exposure is not uniform across Kurnell — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
