New project addresses summer spike in shark attacks along Australian coasts with smart composite surfboard fins
A recently launched research project funded by the Australian Composites Manufacturing Cooperative Research Centre (ACM CRC) addresses the risk of shark attacks on surfers by developing smart surfboard fins with embedded shark-deterrent technologies.
Using advanced composite manufacturing techniques, the research project will develop a shark-repellent design integrating miniaturised sensors, electromagnetic systems, and illumination features directly into the surfboard fin structure. The composite fin will be a novel product with increased safety while maintaining hydrodynamic performance.
The project is being led by Gowing Bros Ltd, UNSW Sydney, and the University of Wollongong. Its recent launch is timely as New South Wales experiences a notable increase in shark encounters.
“With shark activity on the rise, the project takes a proactive approach to coexisting safely with marine predators, combining cutting-edge materials science with surf safety innovation,” John Gowing, Executive Chairman at Gowing Brothers Ltd, said.
“The project demonstrates how innovatively combining advanced manufacturing, safety innovation, and practical commercialisation can address real-world marine safety challenges.
“It positions Australia as a sustained leader in high-tech surfboard manufacturing on the global stage and is an exciting example of how Australian technology can have far-reaching positive impacts.”
Co-funded by the ACM CRC, the project involves strategic investments in embedded sensors, additive manufacturing equipment, and surfboard components, as well as exploration of advanced manufacturing techniques. This includes automated processes for fin and fin box production, surfboard shaping (to incorporate shark-deterrent fins and sensors), composite material deposition, and fin finishing, alongside prototype building.
Commenting on the research initiative, Luke Preston, CEO at ACM CRC, said: “As Australia’s leading research centre for composites manufacturing, we are proud to bring together the greatest academic and industry minds to prove how innovative composite manufacturing and technology can have life-changing impacts.
“By embedding functional technologies into lightweight, composite materials we can support both innovation and practical application, delivering the next generation of surfboards at a time when shark attacks are apparently on the rise.
“This is a world first that is strengthening the capabilities and resilience of Australian surfboard manufacturing, giving us a competitive edge in a crowded global market.”
With worldwide potential, the technology could offer significant economic benefits for Australia. By commercialising smart surfboard fins, the initiative could boost the Australian composites manufacturing sector, create skilled jobs, and contribute to national GDP.
