A living shoreline trial is underway at Three Paddocks Park in Birkdale, aiming to reduce erosion and protect local habitat using natural infrastructure.
Background and Planning Framework
A pilot initiative is underway at Three Paddocks Park in Birkdale, aiming to reduce coastal erosion through a living shoreline design. Redland City officials are leading the project as part of its Coastal Hazard Adaptation Strategy, adopted in 2021. The QCoast2100 program, a state-wide initiative, backs the project.
The park was prioritised for the trial due to its ecological sensitivity and increasing erosion that risks encroaching on adjacent recreational areas. The upcoming trial is one of several nature-based projects flagged for Redland City under this strategy.
Project Methods and Scope
Construction began in June 2025 and is expected to finish in July, subject to weather conditions. Work includes reshaping erosion scarps to safeguard assets like footpaths and exercise stations. Natural elements such as timber log breakwaters and seed trapping devices are being installed to help stabilise the area and promote mangrove recolonisation.
Coastal vegetation including saltmarsh and dune species will be planted to support long-term erosion control. Reef walls will also be used to reduce wave energy and trap sediment. The project will assess the feasibility of this method for future use across the region.
Environmental Considerations and Alternatives
No construction will take place in the adjacent creek, and the project is not expected to affect marine fauna such as turtles. It has been reviewed by specialists in coastal science, including a sea turtle expert from Griffith University. Relevant state departments have approved the plans, including the Department of Environment, Tourism, Science and Innovation.
Unlike traditional coastal defences such as seawalls or bulkheads, the living shoreline approach relies on natural systems. Species like fish, frogs, crabs and turtles are expected to continue using the area without disruption.
Public Access and Site Management
While works are ongoing, a fenced site compound will store materials and equipment. Temporary access changes may occur near Bath Street to accommodate machinery, with alternate pedestrian routes in place. The rest of the park will remain open for public use.
No permanent concrete features are being built. A temporary gravel track will be used to allow machinery access without affecting the site’s stormwater flow.
Future Implications
The trial will provide insight into maintenance needs and construction techniques for similar projects. Another shoreline trial is already funded for rollout later in the year. Redland Bay and Russell Island have also been identified as potential future locations based on the results of this pilot.
The initiative is designed to address long-term environmental risks while supporting community use of coastal spaces in Birkdale.
