Hazard Breakdown
Climate Hazard Breakdown for Brisbane
Flood
Brisbane faces a notable risk of flooding due to its location on the Brisbane River and low-lying areas. Heavy rainfall events can lead to riverine and flash flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
While Brisbane city itself has a lower bushfire risk compared to outer suburbs, areas with nearby bushland are still susceptible, especially during dry periods.
Key drivers:
- ·Drier conditions
- ·Increased fuel load
Heat
Brisbane experiences high temperatures and humidity during summer, leading to heat stress, particularly for vulnerable populations. Climate change is expected to exacerbate these conditions.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
As a coastal city, Brisbane is vulnerable to sea level rise and storm surges. Low-lying areas near the Brisbane River and Moreton Bay are at the highest risk.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity
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 Brisbane's Climate Risk Profile
Brisbane is a vibrant city located in Southeast Queensland, known for its subtropical climate and proximity to the coast. However, this desirable location also brings significant climate-related challenges.
Flooding is a major concern for Brisbane, with the Brisbane River prone to overflowing during periods of heavy rainfall. Past flood events have caused widespread damage and disruption, and climate change is expected to increase the frequency and intensity of these events. Low-lying areas along the river and near Moreton Bay are particularly vulnerable.
Heatwaves are another growing threat, with Brisbane experiencing increasingly high temperatures and humidity during summer. This can lead to heat stress, especially for vulnerable populations such as the elderly and those with chronic health conditions. The urban heat island effect further exacerbates this issue in densely built-up areas.
As a coastal city, Brisbane is also vulnerable to sea level rise and storm surges. These hazards can cause coastal erosion, inundation of low-lying areas, and damage to infrastructure. The impacts of climate change on coastal processes are a significant concern for the city's long-term sustainability.
Addressing these climate risks requires a comprehensive and coordinated approach, involving government, businesses, and the community. Adaptation measures such as improved flood defenses, urban greening, and coastal protection are essential to building resilience and protecting Brisbane's future.
