- Flood
- Illaroo faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Climate change is expected to increase rainfall intensity, exacerbating flood risk.
- Bushfire
- The risk of bushfire in Illaroo is moderate, given the surrounding bushland. Drier conditions and higher temperatures are projected to increase bushfire frequency and intensity.
- Heat
- Illaroo is likely to experience more frequent and intense heatwaves. This poses a significant risk to vulnerable populations, especially during summer.
- 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 (bushfire)
Climate Safety Analysis
Illaroo 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 Illaroo'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 Illaroo 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.

Illaroo (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 bushfire (10.9% of land in high-risk zones), surface flood (9.3% of land in high-risk zones), riverine flood (3.7% of land in high-risk zones). Exposure is not uniform across Illaroo — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
