What This Means for Property Owners
Insurance Outlook
Insurance premiums are likely to increase due to the increasing risk of flooding, coastal erosion, and other climate-related hazards.
Price Impact
Properties in high-risk areas may experience a decrease in value as climate risks become more apparent.
Buyer Checklist
- 1.Check flood maps and bushfire prone land maps.
- 2.Assess the property's vulnerability to coastal erosion.
- 3.Consider the potential impact of heatwaves on the property.
- 4.Inquire about insurance costs and coverage.
- 5.Review the council's climate adaptation plans.
Local Climate Evidence
Flood Evidence
- Nearest Waterway
- Hunter River
- Elevation Range
- 0-150m
- Flood Zone
- Various zones depending on proximity to the Hunter River and coastal areas.
The City of Newcastle has implemented flood mitigation strategies, but ongoing monitoring and adaptation are crucial.

- Distance to Bushland
- Varies, with some suburbs bordering bushland areas.
- Planning Overlay
- Refer to NSW RFS bushfire prone land maps.
- Bushfire Prone Area
- Yes
Residents in bushfire-prone areas should maintain their properties and have a bushfire survival plan.
Heat Evidence
- Avg January Max Temp
- 26.5°C
- Heat Stress Days/Year
- 3 days
Urban areas experience higher temperatures due to the urban heat island effect. Vulnerable populations are at higher risk during heatwaves.
Coastal Evidence
- Distance to Coast
- 0.5 km
- Sea Level Rise Exposure
- Significant exposure in low-lying coastal areas.
- Erosion Risk
- Moderate to high erosion risk along some coastal stretches.
Historical Climate Events
The June 2007 floods caused widespread damage in Newcastle and the Hunter region, with significant inundation of homes and businesses.
SourceBushfires in the Hunter region caused property damage and evacuations, highlighting the risk of bushfires in the area.

Projections based on CSIRO and BOM climate modelling. Scenario: RCP4.5
| Hazard | Today | 2030 | 2050 |
|---|---|---|---|
| flood | 7.5 | 7.8(+0.3) | 8.3(+0.8) |
| bushfire | 4.0 | 4.1(+0.1) | 4.3(+0.3) |
| heat | 7.0 | 7.6(+0.6) | 8.0(+1.0) |
| coastal | 6.5 | 6.9(+0.4) | 7.4(+0.9) |
Under a moderate emissions scenario, Newcastle will experience a slight increase in overall climate risk by 2030. Heatwaves and coastal flooding are projected to become more frequent and intense.

Learn moreAbout Newcastle's Climate Risk Profile
Newcastle, a coastal city in New South Wales, is increasingly vulnerable to the impacts of climate change. The city's location makes it susceptible to a range of hazards, including flooding, bushfires, heatwaves, and coastal erosion.
Flooding is a significant concern due to the Hunter River and its tributaries, as well as the potential for coastal inundation from storm surges. Climate change is expected to increase the intensity of rainfall events, leading to more frequent and severe flooding. Sea level rise will also exacerbate coastal flooding risks.
Bushfire risk is present due to the surrounding bushland areas. While not as high as some other regions, dry conditions and high temperatures can increase the risk of bushfires. Residents should be aware of bushfire safety measures and have a plan in place.
Heatwaves are becoming more frequent and intense in Newcastle, posing a risk to public health, particularly for vulnerable populations. The urban heat island effect can further exacerbate heat stress in built-up areas.
Coastal erosion is another significant concern, with sea level rise threatening coastal infrastructure and properties. Storm surges can also cause significant damage to coastal areas. Adaptation measures are needed to protect coastal communities and ecosystems.
