About Bongaree's Climate Risk Profile

Bongaree, located on Bribie Island, is a popular residential and tourist destination known for its beaches and relaxed lifestyle. However, the suburb is increasingly vulnerable to the impacts of climate change.

Rising sea levels and more intense storms are increasing the risk of coastal flooding and erosion, threatening homes, businesses, and infrastructure. Heatwaves are becoming more frequent and severe, posing a health risk to vulnerable residents, particularly the elderly. Changes in rainfall patterns could also lead to more frequent and intense droughts, impacting water supplies and agriculture.

These climate change impacts could have significant economic and social consequences for Bongaree. Property values could decline as the risk of flooding and coastal erosion increases. Tourism, a major source of income for the suburb, could be affected by extreme weather events and changes in the natural environment. The health and well-being of residents could also be impacted by heatwaves and other climate-related hazards.

It is essential that residents, businesses, and local authorities take action to adapt to the impacts of climate change. This includes investing in infrastructure to protect against flooding and coastal erosion, implementing measures to reduce the urban heat island effect, and promoting water conservation. By working together, the community can build a more resilient and sustainable future for Bongaree.

Addressing climate change requires a multi-faceted approach, including reducing greenhouse gas emissions, adapting to the impacts of climate change, and building community resilience. By taking action now, we can protect the environment, economy, and well-being of future generations.
