Is St Huberts Island, NSW Climate Safe? 2026 Assessment
Climate Safety Score
5.2/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- St Huberts Island is susceptible to flooding due to its low-lying coastal location and proximity to Brisbane Water. Sea level rise and increased rainfall intensity are expected to exacerbate flood risk.
- Bushfire
- Bushfire risk is relatively low due to the island's limited vegetation and surrounding waterways, which act as natural firebreaks. However, dry conditions and strong winds can still pose a threat.
- Heat
- St Huberts Island experiences moderate heat risk, with increasing average temperatures and more frequent heatwaves projected. This can impact vulnerable populations and infrastructure.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2257
- Highest high-risk exposure
- 14% of land (bushfire)
Climate Safety Analysis
St Huberts Island 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 St Huberts Island's climate safety include heat, flood, coastal. 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 St Huberts Island 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.
