About Deagon's Climate Risk Profile

Deagon, located in Queensland, is a suburb that is exposed to a range of climate-related risks. The most significant of these is flooding, due to the suburb's low-lying areas and proximity to waterways. Climate change is projected to increase rainfall intensity, leading to more frequent and severe flooding events.

Heatwaves also pose a considerable risk to Deagon, particularly during the summer months. As temperatures rise due to climate change, the frequency and intensity of heatwaves are expected to increase, potentially impacting the health of vulnerable residents. The urban heat island effect may further exacerbate this risk.

Coastal hazards, such as sea level rise and storm surges, also present a threat to Deagon. The suburb's proximity to Moreton Bay makes it vulnerable to inundation and erosion, which could damage property and infrastructure.

While the risk of bushfires is relatively low in Deagon, it is still important to be aware of the potential threat, especially during dry periods. Nearby bushland areas could pose a risk if not properly managed.

To mitigate these risks, residents and local authorities should take proactive measures, such as improving drainage infrastructure, implementing heatwave early warning systems, and protecting coastal areas. By working together, it is possible to build a more resilient community in Deagon.
