Climate Safety Score
5.5/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Ashby Island is at a high risk of flooding due to its low elevation and proximity to the Clarence River. Climate change is expected to increase the frequency and intensity of heavy rainfall events, exacerbating the risk.
- Bushfire
- The risk of bushfire in Ashby Island is relatively low compared to other areas in NSW, but it's not negligible. The presence of vegetation and dry conditions during summer months can increase the risk.
- Heat
- Ashby Island is expected to experience more frequent and intense heatwaves due to climate change. This can pose a significant risk to vulnerable populations, such as the elderly and those with chronic health conditions.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2463
- Region
- Coastal NSW
- Median property value
- $925,000
- Dominant hazard
- extreme heat (5/10)
