Flood
Deagon faces a moderate risk of flooding due to its low-lying areas and proximity to waterways. Climate change is expected to increase rainfall intensity, exacerbating flood risk.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The bushfire risk in Deagon is relatively low due to the suburb's urban development and limited vegetation. However, nearby bushland areas pose a potential threat during dry periods.
Key drivers:
- ·Proximity to bushland
- ·Dry vegetation
Heat
Deagon experiences a moderate risk of heatwaves, particularly during the summer months. Climate change is projected to increase the frequency and intensity of heatwaves, posing a risk to vulnerable populations.
Key drivers:
- ·Rising temperatures
- ·Urban heat island effect
Coastal
Deagon faces a moderate risk from coastal hazards due to its proximity to Moreton Bay. Sea level rise and storm surges could lead to inundation and erosion.
Key drivers:
- ·Sea level rise
- ·Storm surges

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 Deagon's Climate Risk Profile
Deagon, located in Queensland, is a suburb that is exposed to a range of climate-related risks. The most significant of these is flooding, due to the suburb's low-lying areas and proximity to waterways. Climate change is projected to increase rainfall intensity, leading to more frequent and severe flooding events.
Heatwaves also pose a considerable risk to Deagon, particularly during the summer months. As temperatures rise due to climate change, the frequency and intensity of heatwaves are expected to increase, potentially impacting the health of vulnerable residents. The urban heat island effect may further exacerbate this risk.
Coastal hazards, such as sea level rise and storm surges, also present a threat to Deagon. The suburb's proximity to Moreton Bay makes it vulnerable to inundation and erosion, which could damage property and infrastructure.
While the risk of bushfires is relatively low in Deagon, it is still important to be aware of the potential threat, especially during dry periods. Nearby bushland areas could pose a risk if not properly managed.
To mitigate these risks, residents and local authorities should take proactive measures, such as improving drainage infrastructure, implementing heatwave early warning systems, and protecting coastal areas. By working together, it is possible to build a more resilient community in Deagon.
