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 Mortlake
Flood
Mortlake faces a moderate risk of flooding due to its proximity to the Parramatta River. Climate change is expected to increase rainfall intensity, potentially worsening flood events.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The risk of bushfire in Mortlake is relatively low due to its urban environment and distance from large bushland areas. However, increased temperatures and drier conditions could elevate the risk.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Mortlake is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations, especially the elderly and those with pre-existing health conditions.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Mortlake is exposed to coastal risks due to its location on the Parramatta River. Sea level rise and increased storm surges could lead to inundation and erosion.
Key drivers:
- ·Sea level rise
- ·Increased storm surge

What This Means for Property Owners
Insurance Outlook
Insurance premiums may increase due to flood and coastal risks.
Price Impact
Properties in flood-prone areas may experience price stagnation or decline.
Buyer Checklist
- 1.Check flood maps and historical flood data.
- 2.Assess property's elevation and drainage.
- 3.Consider the cost of flood insurance.
- 4.Evaluate the property's vulnerability to heatwaves.
- 5.Inquire about council's climate adaptation plans.
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 Mortlake's Climate Risk Profile
Mortlake, a suburb in Sydney's Inner West, is increasingly vulnerable to the impacts of climate change. The suburb's proximity to the Parramatta River makes it susceptible to flooding, which is expected to worsen with increased rainfall intensity and sea level rise.
Heatwaves are also a growing concern for Mortlake. Rising global temperatures and the urban heat island effect are likely to lead to more frequent and intense heatwaves, posing a significant risk to public health, particularly for vulnerable populations.
Coastal inundation is another threat to Mortlake. Sea level rise and increased storm surges could lead to the inundation of low-lying areas, causing damage to property and infrastructure.
While the risk of bushfire is relatively low compared to other parts of NSW, it is expected to increase with drier conditions and higher temperatures. Residents should be aware of the potential for bushfires and take steps to protect their properties.
