Holloways and Clifton Beaches in Cairns have faced ongoing erosion for decades, threatening public infrastructure, parklands, and essential roads. ICM provided innovative erosion management solutions that maintained beach access and public use along the foreshore.  Project details Client: Cairns Regional Council Date: 2024 Location: Clifton Beach & Holloways Beach, Cairns, Far North Queensland About this project:    The Challenge:  Holloways and Clifton Beaches experienced severe erosion, leading to the loss of vegetation and the risk of damage to critical public assets. Traditional erosion control methods posed challenges in balancing cost, environmental impact, and public accessibility.  The Solution: ICM conducted a detailed design process to identify the most effective erosion management solution. Through options assessment and cost-benefit analysis, a nearshore breakwater design was selected. This approach combined nature-based principles with low-impact, cost-efficient engineering. The design process included:  Use of the GenCADE sediment transport model to assess beach stabilisation and impacts.  Evaluation of multiple structure types, including groynes, breakwaters, and artificial reefs, using diverse materials such as geotextile structures and pre-cast concrete.  Calibration based on similar structures at Ellis Beach to optimise performance and recreational outcomes.  ICM also prepared detailed technical specifications, safety plans, and an Adaptive Management Plan to address future coastal risks and monitoring requirements.  “Our tailored approach ensures coastal protection solutions that work with nature, safeguarding public infrastructure while enhancing community access and sustainability.” - Sam King, Project Lead, International Coastal Management Services provided  Options Analysis & Cost-Benefit Analysis  Concept & Detailed Design  Technical Specifications & Safety in Design  Approvals & Grant Funding Application Assistance  Graphics Rendering for Community Consultation  Adaptive Management Planning  Get in touch At International Coastal Management, we have over 40 years of experience in designing and implementing coastal erosion solutions.

Following repeated cyclone damage and erosion to the beach adjacent to the Bowen Golf Club, Whitsunday Regional Council engaged ICM to develop a seawall solution to prevent further erosion. ICM designed a durable seawall using repurposed seabees units from a historic Bowen project to prevent future coastal recession and protect golf course assets. Project Details Client: Whitsunday Regional Council Date: 2016 Location: Bowen Golf Club, Queensland About This Project The Challenge: Coastal erosion triggered by multiple cyclones had begun to threaten the beach adjacent to the Bowen Golf Club. The Council sought a cost-effective solution using available materials to minimise project costs while delivering shoreline stability. The Solution: ICM was engaged to assess the viability of using Seabees units - originally from a historic project in Bowen - and to develop a tailored seawall design for the unique conditions of the site. A condition review of existing Seabees units was undertaken, with a stability assessment of the seabees seawall using exiting available units. A concept and detailed design was completed based on the condition and geometry of the existing Seabees. Key structural elements, including the filter layer, toe protection, crest detail and seawall return were engineered for optimal performance. The project successfully reused 266 existing Seabees units, delivering both cost-efficiency and durability. The seawall was constructed from September to November 2017, with ICM providing ongoing support to ensure successful implementation. This project showed how innovative re-use of materials combined with expert coastal engineering, can deliver a cost-effective and resilient erosion solution." - Aaron Salyer, International Coastal Management Services Provided: Seabees condition review Concept design for seawall layout Detailed design including toe, crest, and filter layer Design of seawall return Get in Touch ICM has delivered seawall and coastal protection projects across Queensland using innovative, site-specific designs tailored to natural forces and local materials.

The Northern Gold Coast Beach Protection Strategy (NGCBPS) was designed to provide sustainable, long-term coastal management for the northern Gold Coast. The project successfully widened and protected beaches from erosion while enhancing surfing conditions through innovative engineering solutions. Project Details: Client: Gold Coast City Council Date: 1997-2001 Location: Northern Gold Coast, Queensland, Australia About This Project The Challenge The northern Gold Coast beaches faced significant erosion during storm conditions, threatening coastal resilience and recreational beach use. As a popular surfing destination, the area also required enhancements to improve surfing conditions without compromising environmental sustainability. The Solution The Northern Gold Coast Beach Protection Strategy (NGCBPS) was initiated by  Gold Coast City Council  to provide a sustainable long-term coastal management solution for the Northern Gold Coast.  The primary purpose of the project was to widen and protect the northern Gold Coast beaches from erosion in storm conditions. As this is a popular surfing area, the secondary objective was to improve the surfing amenity. International Coastal Management (ICM) developed and implemented an integrated and sustainable strategy to address these challenges. Key components included: Beach Nourishment : An initial placement of 1.2 million cubic meters of sand to widen the beaches. Nearshore Artificial Reef : Designed as a coastal control point, improving wave quality for surfers while stabilising sand movement. Boulder Wall Completion : Strengthening shoreline defenses against severe weather impacts. Ongoing Maintenance Nourishment : Regular sand replenishment to maintain beach width and storm protection. ICM managed all aspects of the project, including design studies, impact assessment studies, final engineering design, and implementation. Advanced construction techniques using mega sand-filled geotextile containers were used for the reef, ensuring cost-effectiveness, safety, and ecological benefits. The reef provided a substratum for diverse marine life, creating a vibrant ecosystem that exceeded expectations. Monitoring & Results The impact studies included a  cost-benefit study  undertaken by  Griffith Centre for Coastal Management (GCCM) and a comprehensive Environmental Management Plan that was developed with GCCM.  As part of the design studies, physical and numerical modeling was undertaken by Water Research Laboratory (University of NSW), Griffith Centre for Coastal Management and the University of Waikato.  Extensive monitoring has demonstrated the strategy’s success in maintaining an increased storm buffer during significant wave events (up to Hmax >13m) and enhancing surfing conditions. The reef has also become a valued recreational diving and fishing destination, adding ecological and community benefits. The mega sand filled geotextile containers used for construction of the reef have proved to be a safe and economical construction material. The monitoring has provided data to facilitate improvements to the geotextile materials and container design. The non-woven Terrafix geotextile has also provided an excellent substratum for a diverse range of marine vegetation and the extent and diversity of the marine habitat formed has greatly exceeded expectations. The development of this diverse marine ecosystem contributes to the environmental value of the reef structure as well as providing a new recreational dive and fishing location. “The North Gold Coast Beach Protection Strategy demonstrates how innovative engineering and environmental integration can deliver long-term resilience and recreational value to our coastlines.” - Angus Jackson, International Coastal Management Services Provided: Coastal Management Strategy Development Beach Nourishment Design & Implementation Artificial Reef Design & Construction Impact Assessment Studies (IAS) Environmental Management Plans (EMP) Monitoring & Maintenance -> Learn more about the Northern Gold Coast Beach Protection Strategy .
