Hazard Breakdown
Climate Hazard Breakdown for St Lucia
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
Wind
Notable wind risk — tropical cyclone wind fields
Storm
Notable storm risk — cyclones and thunderstorms
Social
Moderate social stability — growth regions
Energy
Elevated energy costs — high cooling demand

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.
