Hazard Breakdown
Climate Hazard Breakdown for Hope Island
Flood
Hope Island is susceptible to flooding due to its low-lying coastal location and proximity to waterways. Climate change is expected to increase rainfall intensity and sea levels, exacerbating flood risk.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Bushfire risk in Hope Island is relatively low due to the suburb's developed nature and limited vegetation. However, nearby bushland areas pose a potential threat during dry periods.
Key drivers:
- ·Proximity to bushland
- ·Dry vegetation
Heat
Hope Island experiences high temperatures during summer, with heatwaves becoming more frequent and intense due to climate change. This poses a risk to vulnerable populations.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
As a coastal suburb, Hope Island is vulnerable to sea level rise and coastal erosion. Climate change is expected to worsen these impacts, threatening infrastructure and property.
Key drivers:
- ·Sea level rise
- ·Increased 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 Hope Island's Climate Risk Profile
Hope Island, located on the Gold Coast, is a predominantly residential suburb with a mix of waterfront properties and golf course developments. Its low-lying coastal location makes it particularly vulnerable to the impacts of climate change.
Flooding is a significant concern, with the potential for both riverine and coastal inundation. Increased rainfall intensity and rising sea levels are expected to exacerbate flood risk in the coming decades. Residents should be aware of flood warnings and have a plan in place to protect their property.
Heatwaves are also becoming more frequent and intense, posing a risk to vulnerable populations such as the elderly and those with chronic health conditions. Taking steps to stay cool during hot weather is essential.
Coastal erosion is another threat, with the potential to damage infrastructure and property along the waterfront. Protecting coastal areas through appropriate management strategies is crucial.
Overall, Hope Island faces a range of climate-related challenges that require proactive adaptation measures to ensure the suburb's long-term resilience.
