Climate Safety Score
5.8/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Newcastle East faces a moderate risk of flooding due to its proximity to the Hunter River and coastal location. Heavy rainfall events can lead to riverine and flash flooding.
- Bushfire
- The bushfire risk in Newcastle East is relatively low due to its urban environment and limited vegetation. However, ember attacks from distant fires are still a potential concern.
- Heat
- Newcastle East is susceptible to heatwaves, with increasing average temperatures posing a risk to vulnerable populations. Urban heat island effect can exacerbate the impact.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2300
- Highest high-risk exposure
- 15.1% of land (surface flood)
Climate Safety Analysis
Newcastle East 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 Newcastle East'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 Newcastle East 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.
