Is Wallis Lake, NSW Climate Safe? 2026 Assessment
Climate Safety Score
5.8/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Wallis Lake is susceptible to flooding due to its low-lying areas and proximity to Wallis Lake. Increased rainfall intensity could exacerbate flood risks.
- Bushfire
- Bushfire risk is present due to surrounding vegetation. Drier conditions and higher temperatures could increase the likelihood and intensity of bushfires.
- Heat
- Wallis Lake is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations and infrastructure.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2428
- Highest high-risk exposure
- 8.9% of land (surface flood)
Climate Safety Analysis
Wallis Lake 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 Wallis Lake's climate safety include heat, flood, coastal. 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 Wallis Lake 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 Wallis Lake including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
Wallis Lake (postcode 2428) 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 (8.9% of land in high-risk zones), bushfire (8.7% of land in high-risk zones), extreme wind (3.8% of land in high-risk zones). Exposure is not uniform across Wallis Lake — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.

Which climate hazard poses the biggest risk in Wallis Lake?
The dominant hazard for Wallis Lake depends on geography and local environment. Proximity to waterways elevates flood risk, while proximity to bushland increases bushfire risk. ClimateNest's multi-hazard analysis identifies the highest-risk hazards for any specific address.
How does Wallis Lake compare to nearby suburbs for climate safety?
Nearby suburbs may have different climate risk profiles depending on elevation, vegetation cover, drainage patterns, and land use. ClimateNest allows comparison of climate safety scores across New South Wales suburbs.
Should I be concerned about buying property in Wallis Lake?
Climate risk should be one factor in your decision, alongside price, location, and amenity. An informed buyer understands the specific risks at a property address and factors insurance costs and climate projections into their assessment of long-term value.
What climate projections should I know for Wallis Lake?
Key projections for New South Wales from CSIRO include increased average temperatures, more frequent hot days, changes in rainfall seasonality, longer fire seasons, and potential increases in extreme rainfall intensity. These trends inform the long-term outlook for Wallis Lake.
What share of Wallis Lake is exposed to high surface flood risk?
ClimateNest's hazard overlay maps 8.9% of Wallis Lake in high-risk zones for surface flood, with a further 70.3% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
