Is Dangar Island, NSW Climate Safe? 2026 Assessment
Climate Safety Score
5.8/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Dangar Island is susceptible to flooding due to its low-lying topography and proximity to the Hawkesbury River. Riverine flooding can inundate properties and disrupt transportation.
- Bushfire
- While Dangar Island is surrounded by water, bushfire risk exists due to vegetation on the island and potential for embers to travel from the mainland. Dry conditions and strong winds can exacerbate the risk.
- Heat
- Dangar Island experiences high temperatures during summer, with potential for heatwaves. The island's location can lead to increased humidity, exacerbating heat stress.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2083
- Region
- Greater Sydney
- Median property value
- $1.6 million
- Dominant hazard
- extreme heat (5/10)
- Highest high-risk exposure
- 12.8% of land (bushfire)
