Is Mulgrave, NSW Climate Safe? 2026 Assessment
Climate Safety Score
7.2/10Climate risk is high — address assessment recommended
Key Facts
- Climate Safety
- High
- Flood
- Mulgrave is at high risk of flooding due to its location on the Hawkesbury River floodplain. Climate change is expected to increase the frequency and intensity of heavy rainfall events, exacerbating flood risk.
- Bushfire
- Mulgrave faces a moderate bushfire risk due to surrounding bushland. Hotter, drier conditions caused by climate change are projected to increase bushfire frequency and intensity.
- Heat
- Mulgrave is likely to experience more frequent and intense heatwaves due to climate change. This poses a 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
- 2756
- Highest high-risk exposure
- 11.6% of land (bushfire)
Climate Safety Analysis
Mulgrave 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 Mulgrave'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 Mulgrave 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.
