Bribie Island erosion and breakthrough review

The Queensland Government is undertaking a review of the Bribie Island erosion and breakthrough events to understand the events and their impact and work towards the safety and prosperity of nearby communities.

Ongoing erosion has severely narrowed the width of the northern tip of Bribie Island, creating several weak points. In 2022, large waves cut a new channel through the weakest part of the northern tip of Bribie Island opposite Nelson Street, Golden Beach. This channel rapidly widened and became a new opening to the ocean. Soon after, the original Caloundra Bar closed over, constraining boat passage and access including for the Caloundra Coast Guard.

Further severe weather caused by Tropical Cyclone Alfred in 2025 has further widened the 2022 breakthrough and caused more damage, including extensive erosion to the foredune at Lions Park. This event also created a second breakthrough south of Lions Park. These events have heightened residents and business owner concerns about future risk and impacts, given the Northern tip of Bribie Island has traditionally shielded Caloundra from effects of severe weather.

The review responds to community concerns raised before, during and after ex-Tropical Cyclone Alfred’s impact on the coast.

The department appointed experts with international experience in coastal engineering, RPS, who is partnering with International Coastal Management to undertake the review.

The Queensland Government is committed to understanding the unique needs and priorities of the local community and stakeholders.

Local residents and stakeholders are encouraged to have their say throughout the review process.

Consultation process

Community consultation is integral to this project. Local communities and stakeholders will have the opportunity to provide feedback through the review.

Round 1 of consultation closed in May 2025, and provided the opportunity for residents and other stakeholders to have their say on the issue. The feedback received in Round 1 will be considered in conjunction with research undertaken by RPS and ICM to guide immediate actions for Government consideration.

Round 2 of community consultation will provide an opportunity for stakeholders to provide feedback on draft recommendations of the coastal engineering experts, ahead of a final review report delivered later this year.

Findings from Part 1 – Desktop review

Part 1 of the independent review into the Bribie Island erosion and breakthrough events is now available. This report presents a detailed desktop analysis of erosion and breakthrough events on northern Bribie Island, including significant changes observed in 2022 and 2025.

Drawing on more than 200 historical and technical sources, including government reports, academic research and local insights, the report consolidates decades of scientific evidence to provide a clear understanding of the natural, social and policy context surrounding these events.

The information in part 1 lays the groundwork for the rest of the review, which will delve into short and longer term actions to improve coast resilience and reduce risk to nearby communities and infrastructure.
