About Redland Bay's Climate Risk Profile

Redland Bay, a coastal suburb in Queensland, is increasingly vulnerable to the impacts of climate change. The primary risks include flooding from intense rainfall and sea level rise, heatwaves with rising average temperatures, and coastal erosion due to storm surges.

Flooding is a significant concern due to the suburb's low-lying topography and proximity to Moreton Bay. Increased rainfall intensity and rising sea levels exacerbate the risk of both riverine and coastal flooding, potentially impacting homes, businesses, and infrastructure.

Heatwaves are becoming more frequent and intense, posing a threat to vulnerable populations, particularly the elderly and those with pre-existing health conditions. The urban heat island effect can further amplify temperatures in built-up areas.

Coastal erosion is another major concern, with rising sea levels and more frequent storm surges threatening to erode beaches and damage coastal properties. This can have significant economic and social impacts on the community.

Residents and property owners should take proactive steps to mitigate these risks, including investing in flood protection measures, improving home cooling, and supporting local government initiatives to address climate change.
