A report published today highlights growing concerns about the long-term impact of rising sea levels on the Sunshine Coast, with several coastal suburbs identified as particularly exposed to flooding risks. Areas including Bokarina, Parrearra and Warana are among those facing significant current flood exposure, while Mooloolaba and other low-lying coastal communities could face increasing risks in coming decades.

The report warns that rising sea levels could increase the frequency and severity of coastal flooding, potentially affecting homes, infrastructure, insurance costs and property values. Low-lying areas close to waterways and the coastline are considered particularly vulnerable to tidal surges and flooding.

For Sunshine Coast residents, the issue is not limited to future environmental changes. Researchers warn that even relatively small increases in sea level can significantly increase the frequency of major coastal flooding events. This could create additional pressure for councils and governments to invest in drainage, coastal protection and other adaptation measures.

The Sunshine Coast is already undertaking coastal protection and infrastructure projects, including work around Moffat Beach, Golden Beach and Mooloolaba, as the region continues to plan for changing coastal conditions.

The report also raises concerns about the potential effect on property markets. As flood risks increase, some coastal properties could face higher insurance premiums and reduced buyer demand. However, the impact is expected to vary considerably between suburbs depending on elevation, proximity to waterways and the effectiveness of future adaptation measures.

The findings add to the broader discussion about how rapidly growing coastal communities should prepare for climate-related risks while continuing to accommodate new residents and development.
