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 Gawler
Flood
Gawler faces a moderate risk of flooding due to its proximity to the Gawler River and other waterways. Heavy rainfall events can lead to riverine flooding, impacting properties and infrastructure.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
The risk of bushfire in Gawler is moderate, with areas of bushland surrounding the town. Hot, dry conditions during summer increase the likelihood of bushfires.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Gawler experiences high temperatures during summer, leading to heatwave conditions. Climate change is expected to increase the frequency and intensity of heatwaves, posing a risk to vulnerable populations.
Key drivers:
- ·Climate change
- ·Urban heat island effect
Coastal
Gawler is located inland and does not face a direct risk from coastal hazards such as sea level rise or coastal erosion.
Key drivers:
- ·Distance from coast

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 Gawler's Climate Risk Profile
Gawler, located in South Australia, is subject to a range of climate-related risks. The most significant of these is flooding, due to the town's proximity to the Gawler River and other waterways. Heavy rainfall events can cause the river to overflow, inundating properties and disrupting infrastructure. Climate change is projected to increase the intensity of rainfall events, further increasing the risk of flooding in the future.
Bushfire risk is also a concern, particularly during the hot, dry summer months. Areas of bushland surrounding Gawler can provide fuel for bushfires, which can spread rapidly under windy conditions. While the risk is moderate, residents should be prepared for the possibility of bushfires.
Heatwaves are another significant hazard, with Gawler experiencing high temperatures during summer. Climate change is expected to increase the frequency and intensity of heatwaves, posing a risk to vulnerable populations such as the elderly and those with chronic health conditions.
Coastal risks are minimal, as Gawler is located inland and is not directly exposed to sea level rise or coastal erosion. However, the town may be indirectly affected by coastal hazards through impacts on regional infrastructure and supply chains.
Addressing these climate risks will require a combination of adaptation and mitigation measures. Adaptation measures include improving flood defenses, managing vegetation to reduce bushfire risk, and implementing heatwave early warning systems. Mitigation measures include reducing greenhouse gas emissions to slow 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.
