Flood
St Lucia is located near the Brisbane River and is susceptible to flooding from heavy rainfall and riverine overflow. The area has a history of flooding, and climate change is expected to increase the frequency and intensity of extreme rainfall events.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
St Lucia has a relatively low bushfire risk due to its urban environment and limited vegetation. However, there are some areas with nearby bushland that could pose a risk during extreme bushfire conditions.
Key drivers:
- ·Proximity to bushland
- ·Dry vegetation
Heat
St Lucia is expected to experience more frequent and intense heatwaves due to climate change. This will increase the risk of heat stress and heatstroke, particularly for vulnerable populations.
Key drivers:
- ·Rising temperatures
- ·Urban heat island effect
Coastal
Located on the Brisbane River, St Lucia faces potential impacts from sea level rise and storm surges. While not directly on the coast, the riverine environment makes it vulnerable to tidal influences and increased flooding during coastal events.
Key drivers:
- ·Sea level rise
- ·Storm surge

Detailed Hazard Analysis
heat Risk
St Lucia is expected to experience more frequent and intense heatwaves due to climate change. This will increase the risk of heat stress and heatstroke, particularly for vulnerable populations.
Primary Drivers
- ·Rising temperatures
- ·Urban heat island effect
- ·Increased humidity
flood Risk
St Lucia is located near the Brisbane River and is susceptible to flooding from heavy rainfall and riverine overflow. The area has a history of flooding, and climate change is expected to increase the frequency and intensity of extreme rainfall events.
Primary Drivers
- ·Increased rainfall intensity
- ·Sea level rise
- ·Urban development
coastal Risk
Located on the Brisbane River, St Lucia faces potential impacts from sea level rise and storm surges. While not directly on the coast, the riverine environment makes it vulnerable to tidal influences and increased flooding during coastal events.
Primary Drivers
- ·Sea level rise
- ·Storm surge
- ·Erosion
bushfire Risk
St Lucia has a relatively low bushfire risk due to its urban environment and limited vegetation. However, there are some areas with nearby bushland that could pose a risk during extreme bushfire conditions.
Primary Drivers
- ·Proximity to bushland
- ·Dry vegetation
- ·High temperatures
What This Means for Property Owners
Insurance Outlook
Increased premiums are likely due to flood risk.
Price Impact
Potential for decreased property values in flood-prone areas.
Buyer Checklist
- 1.Check flood maps and historical flood data.
- 2.Assess property's elevation and drainage.
- 3.Obtain flood insurance.
- 4.Consider heat mitigation measures.
- 5.Evaluate bushfire risk if near bushland.
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 St Lucia's Climate Risk Profile
St Lucia, a suburb of Brisbane, Queensland, is exposed to a range of climate-related risks. Its location near the Brisbane River makes it particularly vulnerable to flooding, both from heavy rainfall and riverine overflow. Climate change is expected to increase the frequency and intensity of extreme rainfall events, further elevating the flood risk.
Heatwaves are another significant concern for St Lucia. As temperatures rise, the suburb is projected to experience more frequent and intense heatwaves, increasing the risk of heat stress and heatstroke, especially for vulnerable populations. The urban environment can exacerbate this effect through the urban heat island phenomenon.
While bushfire risk is relatively lower compared to other areas, St Lucia still faces some threat due to its proximity to bushland. During dry periods and extreme bushfire conditions, these areas could pose a risk to the suburb.
Located on the Brisbane River, St Lucia is also susceptible to the impacts of sea level rise and storm surges. Although not directly on the coast, the riverine environment makes it vulnerable to tidal influences and increased flooding during coastal events. Residents should stay informed about potential risks and take proactive measures to protect their properties and well-being.
