Climate Safety Score
5.5/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Wirrimbi faces a moderate risk of flooding. This risk is primarily due to heavy rainfall events and the potential for flash flooding in low-lying areas.
- Bushfire
- Wirrimbi has a high bushfire risk due to its proximity to bushland and prevailing dry conditions. The risk is exacerbated by increasing temperatures and prolonged droughts.
- Heat
- Wirrimbi is likely to experience more frequent and intense heatwaves. This poses a significant risk to vulnerable populations, including 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
- 2447
- Highest high-risk exposure
- 15.7% of land (bushfire)
Climate Safety Analysis
Wirrimbi 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 Wirrimbi'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 Wirrimbi 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 Wirrimbi including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
Wirrimbi (postcode 2447) 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 (15.7% of land in high-risk zones), surface flood (13.8% of land in high-risk zones), extreme wind (5.4% of land in high-risk zones). Exposure is not uniform across Wirrimbi — 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 Wirrimbi?
The dominant hazard for Wirrimbi 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 Wirrimbi 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 Wirrimbi?
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 Wirrimbi?
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 Wirrimbi.
What share of Wirrimbi is exposed to high bushfire risk?
ClimateNest's hazard overlay maps 15.7% of Wirrimbi in high-risk zones for bushfire, with a further 57.6% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
