Is Lost River, NSW Climate Safe? 2026 Assessment
Climate Safety Score
7.2/10Climate risk is high — address assessment recommended
Key Facts
- Climate Safety
- High
- Flood
- Lost River faces a moderate risk of flooding due to its proximity to waterways and historical rainfall patterns. Climate change is expected to increase the intensity of rainfall events, potentially leading to more frequent and severe flooding.
- Bushfire
- The area surrounding Lost River is susceptible to bushfires, particularly during dry periods. Higher temperatures and prolonged droughts, exacerbated by climate change, are increasing the risk of bushfires in the region.
- Heat
- Lost River is likely to experience more frequent and intense heatwaves as a result of climate change. This poses a risk to vulnerable populations, such as the elderly and those with pre-existing health conditions.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2583
- Highest high-risk exposure
- 12% of land (riverine flood)
Climate Safety Analysis
Lost River in New South Wales has an overall climate safety rating of High. 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 Lost River's climate safety include heat, flood, bushfire. 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 Lost River 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.
