Overall Risk Score
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 Allawah
Flood
Allawah has a moderate risk of flooding due to its proximity to the Georges River and low-lying areas. Climate change is expected to increase rainfall intensity, exacerbating flood risk.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Allawah has a relatively low risk of bushfire due to its urban environment and distance from large bushland areas. However, increased temperatures and drier conditions could slightly increase the risk.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Allawah is expected to experience more frequent and intense heatwaves due to climate change. This poses a significant risk to vulnerable populations, such as the elderly and those with chronic health conditions.
Key drivers:
- ·Increased greenhouse gas emissions
- ·Urban heat island effect
Coastal
Allawah faces a moderate risk from coastal hazards due to its proximity to the Georges River estuary. Sea level rise and increased storm surge could lead to inundation and erosion.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity

What This Means for Property Owners
Insurance Outlook
Insurance premiums are likely to increase in the future due to the increasing risk of flooding and other climate-related hazards.
Price Impact
Properties in flood-prone areas may experience a decrease in value due to the increasing risk of damage.
Buyer Checklist
- 1.Check flood maps and historical flood data.
- 2.Assess the property's vulnerability to heatwaves.
- 3.Consider the potential impacts of sea level rise.
- 4.Obtain adequate insurance coverage.
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 Allawah's Climate Risk Profile
Allawah, a suburb in southern Sydney, is increasingly vulnerable to the impacts of climate change. The primary risks include flooding from the Georges River, more intense and frequent heatwaves, and coastal inundation due to sea level rise.
The suburb's proximity to the Georges River makes it susceptible to flooding, particularly during periods of heavy rainfall. Climate change is projected to increase rainfall intensity, leading to more frequent and severe flood events. This can cause damage to properties, disrupt transportation, and pose risks to human safety.
Heatwaves are also a growing concern for Allawah. As temperatures rise, the suburb is expected to experience more days of extreme heat, which can lead to heat stress, dehydration, and other health problems, especially for vulnerable populations. The urban environment of Allawah can exacerbate the heat island effect, making the suburb even hotter than surrounding areas.
Sea level rise poses a long-term threat to Allawah, particularly to properties located near the Georges River estuary. Increased sea levels can lead to coastal inundation, erosion, and saltwater intrusion, which can damage infrastructure and ecosystems.
Addressing these climate risks requires a combination of adaptation and mitigation measures. Adaptation strategies include improving flood defenses, implementing heatwave early warning systems, and planning for sea level rise. Mitigation efforts focus on reducing greenhouse gas emissions to slow down the pace of climate change.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
