Climate Safety Score
7.2/10Climate risk is high — address assessment recommended
Key Facts
- Climate Safety
- High
- Flood
- Wallanthery faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Intense rainfall events can lead to riverine and flash flooding.
- Bushfire
- The area surrounding Wallanthery is prone to bushfires, particularly during hot and dry conditions. The presence of dry vegetation increases the risk of fire ignition and spread.
- Heat
- Wallanthery experiences high temperatures during summer, leading to heat stress for vulnerable populations. Climate change is expected to exacerbate heatwaves.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2675
- Highest high-risk exposure
- 13.8% of land (bushfire)
Climate Safety Analysis
Wallanthery in New South Wales has an overall climate safety rating of High. 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 Wallanthery's climate safety include heat, 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 Wallanthery 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 Wallanthery including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
Wallanthery (postcode 2675) 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 (13.8% of land in high-risk zones), surface flood (11.1% of land in high-risk zones), extreme wind (6.5% of land in high-risk zones). Exposure is not uniform across Wallanthery — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
