Hazard Breakdown
Flood, bushfire, heat, coastal and storm exposure are all assessed in this area. The score that matters is the property's own: a ClimateNest report scores the address across eight hazards, with insurance and value projections to 2050.
Climate Hazard Breakdown for Port Stephens
Flood
Port Stephens faces a moderate risk of flooding due to its low-lying coastal areas and proximity to waterways. Increased rainfall intensity and sea level rise are expected to exacerbate this risk.
Key drivers:
- ·Sea level rise
- ·Increased rainfall intensity
Bushfire
The risk of bushfires in Port Stephens is moderate, with areas of bushland surrounding residential zones. Drier conditions and higher temperatures are projected to increase the frequency and intensity of bushfires.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Port Stephens is likely to experience more frequent and intense heatwaves. Higher average temperatures can pose health risks, especially for vulnerable populations.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
As a coastal community, Port Stephens is vulnerable to the impacts of sea level rise and coastal erosion. This can lead to inundation of low-lying areas and damage to infrastructure.
Key drivers:
- ·Sea level rise
- ·Coastal erosion

How the region's climate is projected to change
Regional projections, not a forecast for this street. Figures are from the WA Department of Water and Environmental Regulation's climate projections for the South Western Flatlands region, which draws on CSIRO and Bureau of Meteorology modelling.
Temperature
+0.5 to 1.1°C by 2030
Above the 1986–2005 climate, on all emissions scenarios. By 2090, 1.2 to 2.0°C under intermediate emissions or 2.6 to 4.0°C under high emissions.
Rainfall
Winter rain down up to 15% by 2030
The South West has been drying since 1970, and the decline has been larger than anywhere else in Australia. Heavy rainfall events are projected to become more intense even as totals fall.
Fire weather
Harsher, magnitude uncertain
High confidence that fire weather becomes harsher, low confidence in the size of the change, because it depends heavily on summer rainfall.
Sea level
+0.12 m by 2030
At the Fremantle gauge, range 0.07 to 0.16 m. Very high confidence that sea levels continue to rise through the century.

Learn moreAbout Port Stephens's Climate Risk Profile
Port Stephens, a coastal region in New South Wales, is increasingly vulnerable to the impacts of climate change. Rising sea levels, more intense rainfall, and higher temperatures are expected to exacerbate existing risks and create new challenges for the community.
Flooding is a significant concern, with low-lying areas susceptible to inundation from heavy rainfall and storm surges. The risk is projected to increase as sea levels rise and rainfall patterns become more erratic. Bushfire risk is also elevated due to drier conditions and increased vegetation dryness.
Heatwaves are becoming more frequent and intense, posing a threat to public health, especially for the elderly and those with pre-existing conditions. Coastal erosion and inundation are also major concerns, threatening infrastructure and natural ecosystems.
Addressing these challenges requires a coordinated effort from all levels of government, as well as community involvement. Adaptation measures, such as improved drainage, bushfire mitigation strategies, and coastal protection works, are essential to protect the region's assets and ensure a sustainable future.
