Learn moreAbout Broadbeach's Climate Risk Profile
Broadbeach, located on the Gold Coast, is a vibrant suburb known for its beaches, dining, and entertainment. However, its coastal location makes it particularly vulnerable to the impacts of climate change.
Rising sea levels pose a significant threat to Broadbeach, increasing the risk of coastal inundation and erosion. Storm surges associated with cyclones can also cause widespread damage to infrastructure and property. The increasing frequency and intensity of heatwaves can exacerbate health risks, especially for vulnerable populations such as the elderly and those with chronic illnesses.
Changes in rainfall patterns can lead to both increased flooding and prolonged droughts, impacting water resources and ecosystems. The potential for bushfires, while lower than in some other areas, remains a concern during dry periods.
Addressing these climate risks requires a coordinated effort from government, businesses, and the community. Adaptation measures such as seawalls, improved drainage systems, and heatwave preparedness plans are essential to protect Broadbeach from the impacts of climate change. Mitigation efforts to reduce greenhouse gas emissions are also crucial to slow the pace of climate change and minimize future risks.
