Is Twelve Mile Peg, NSW Climate Safe? 2026 Assessment
Climate Safety Score
5.5/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- The area may experience some flooding, particularly during periods of heavy rainfall. Local waterways and drainage systems can be overwhelmed, leading to potential property damage and disruption.
- Bushfire
- The suburb faces a moderate risk of bushfires due to the proximity of bushland. Hot, dry conditions and strong winds can increase the likelihood and intensity of bushfires.
- Heat
- The area is likely to experience heatwaves and high temperatures, particularly during the summer months. This can pose a risk to vulnerable populations and increase energy demand.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2540
- Highest high-risk exposure
- 10.9% of land (riverine flood)
Climate Safety Analysis
Twelve Mile Peg 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 Twelve Mile Peg's climate safety include heat, 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 Twelve Mile Peg 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 Twelve Mile Peg including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
Twelve Mile Peg (postcode 2540) 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 riverine flood (10.9% of land in high-risk zones), bushfire (8.6% of land in high-risk zones), surface flood (8.1% of land in high-risk zones). Exposure is not uniform across Twelve Mile Peg — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
