Confidence: Medium
Hazard Breakdown
Climate Hazard Breakdown for Gold Coast
Flood
The Gold Coast faces a notable risk of flooding due to its coastal location and numerous waterways. Intense rainfall events can lead to riverine and flash flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Bushfire risk is present in areas of the Gold Coast that border bushland. Hot, dry conditions and strong winds can exacerbate the risk.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
The Gold Coast 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 average temperatures
- ·Increased frequency of heatwaves
Coastal
Coastal erosion and inundation are significant threats to the Gold Coast due to sea level rise and storm surges. Low-lying areas are particularly vulnerable.
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 Gold Coast's Climate Risk Profile
The Gold Coast, renowned for its beaches and waterways, is increasingly vulnerable to the impacts of climate change. Rising sea levels threaten coastal infrastructure and ecosystems, while more frequent and intense rainfall events increase the risk of flooding.
Heatwaves are becoming more common and severe, posing a risk to public health, especially for vulnerable populations. Bushfire risk is also present in areas bordering bushland, with hot, dry conditions increasing the likelihood of fires.
These climate change impacts have implications for property values, insurance costs, and the overall livability of the Gold Coast. It is crucial for residents, businesses, and local authorities to take proactive measures to mitigate these risks and adapt to a changing climate.
Adaptation strategies include improving drainage infrastructure, implementing coastal protection measures, promoting energy efficiency, and enhancing community resilience. By working together, the Gold Coast can build a more sustainable and climate-resilient future.
