Is Sunderland Bay, VIC Climate Safe? 2026 Assessment
Climate Safety Score
5.5/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Sunderland Bay faces a moderate risk of flooding, primarily from coastal inundation and storm surges due to its proximity to the coast and low-lying areas. While not directly on a major river, drainage systems and overland flow paths can exacerbate flooding during intense rainfall events.
- Bushfire
- The bushfire risk in Sunderland Bay is moderate, with areas of coastal heathland and nearby bushland posing a potential threat. While the suburb itself has limited dense vegetation, prevailing winds can carry embers from surrounding areas.
- Heat
- Sunderland Bay experiences a significant heat risk, with a substantial number of days exceeding 35°C projected to increase. Coastal breezes offer some relief, but prolonged heatwaves can still impact vulnerable populations and infrastructure.
- Storm
- Moderate storm risk — severe thunderstorms with hail and damaging winds
- Postcode
- 3922
- Highest high-risk exposure
- 10.7% of land (bushfire)
Climate Safety Analysis
Sunderland Bay in Victoria 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 Sunderland Bay's climate safety include heat, 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 Sunderland Bay 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.
