Climate Safety Score
5.8/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Wallalong faces a notable risk of flooding due to its proximity to the Hunter River and low-lying areas. Climate change is expected to increase the frequency and intensity of heavy rainfall events, exacerbating flood risk.
- Bushfire
- Bushfire risk in Wallalong is moderate. While not immediately surrounded by dense bushland, the area is susceptible to grassfires and ember attacks during dry periods. Climate change is projected to lengthen the fire season and increase fire intensity.

- Wallalong is likely to experience more frequent and intense heatwaves. Higher average temperatures and prolonged periods of extreme heat can pose health risks, particularly for vulnerable populations.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2320
- Highest high-risk exposure
- 11.2% of land (bushfire)
