Hazard Breakdown
Climate Hazard Breakdown for Broadbeach
Flood
Broadbeach faces a moderate risk of flooding due to its low-lying coastal location and proximity to waterways. Intense rainfall events can lead to stormwater inundation and riverine flooding.
Key drivers:
- ·Sea level rise
- ·Increased rainfall intensity
Bushfire
The risk of bushfire in Broadbeach is relatively low due to its urban development and limited vegetation. However, dry conditions and strong winds can increase the risk.
Key drivers:
- ·Dry conditions
- ·Strong winds
Heat
Broadbeach experiences high temperatures and humidity during summer, leading to heat stress. Climate change is expected to increase the frequency and intensity of heatwaves.
Key drivers:
- ·Rising temperatures
- ·Urban heat island effect
Coastal
Broadbeach is highly vulnerable to coastal hazards such as sea level rise, storm surge, and coastal erosion. These hazards can damage infrastructure, property, and ecosystems.
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 Broadbeach's Climate Risk Profile
Broadbeach, located on the Gold Coast, is a popular tourist destination known for its beaches, shopping, and entertainment. However, the suburb is increasingly vulnerable to the impacts of climate change.
Flooding is a significant concern due to the suburb's low-lying coastal location and proximity to waterways. Intense rainfall events can overwhelm stormwater drainage systems and cause widespread inundation. Sea level rise is exacerbating the risk of coastal flooding and erosion.
Heatwaves are becoming more frequent and intense, posing a threat to public health, especially for vulnerable populations. The urban heat island effect further amplifies temperatures in built-up areas.
Coastal hazards such as storm surge and coastal erosion are also major threats. Sea level rise is increasing the vulnerability of coastal infrastructure and property to damage from these events.
Addressing these climate risks requires a combination of adaptation and mitigation measures. Adaptation strategies include improving stormwater drainage, building seawalls, and implementing heatwave early warning systems. Mitigation efforts focus on reducing greenhouse gas emissions to slow the pace of climate change.
