Is Number One, NSW Climate Safe? 2026 Assessment
Climate Safety Score
5.5/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Number One faces a moderate risk of flooding, primarily from heavy rainfall events and potential riverine flooding. Climate change is expected to increase the intensity of rainfall, exacerbating this risk.
- Bushfire
- The risk of bushfire in Number One is moderate due to the presence of surrounding bushland. Hotter, drier conditions driven by climate change are projected to increase the frequency and intensity of bushfires.
- Heat
- Number One is likely to experience more frequent and intense heatwaves. This poses a significant risk to vulnerable populations, such as the elderly and those with pre-existing health conditions.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2424
- Highest high-risk exposure
- 8.8% of land (bushfire)
Climate Safety Analysis
Number One 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 Number One'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 Number One 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 Number One including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
Number One (postcode 2424) 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 (8.8% of land in high-risk zones), surface flood (8.1% of land in high-risk zones), riverine flood (4.8% of land in high-risk zones). Exposure is not uniform across Number One — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.

Frequently Asked Questions
Is Number One safe from climate change?
No location in Australia is entirely immune to climate change impacts. Number One has an overall Medium climate risk rating. Understanding the specific hazards at your property address — not just the suburb average — provides the most reliable risk picture.
Which climate hazard poses the biggest risk in Number One?
The dominant hazard for Number One 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 Number One 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 Number One?
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 Number One?
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 Number One.
What share of Number One is exposed to high bushfire risk?
ClimateNest's hazard overlay maps 8.8% of Number One in high-risk zones for bushfire, with a further 85.2% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
