ACM CRC Backs Manufacturing Project to Develop Smart Surfboard Fins Aimed at Reducing Shark Attack Risks

Why It Matters

The technology offers a practical response to increasing shark‑encounter rates, opening a new safety‑focused product line for the composites sector. It also promises job creation and strengthens Australia’s export competitiveness in advanced surf equipment.

Key Takeaways

• Smart fins embed sensors, EM deterrents, and LEDs within composite structure
• Project leverages additive manufacturing and automated fin‑box production
• Collaboration unites Gowing Bros, UNSW, University of Wollongong, and ACM CRC
• Expected outcomes include surfer safety, job growth, and export‑ready surf tech

Pulse Analysis

Shark encounters have surged along Australia’s coastline, prompting both public safety concerns and a market opportunity for innovative protection solutions. While traditional deterrents rely on external devices, the new smart fin concept integrates safety features at the material level, allowing surfers to maintain performance without additional gear. By embedding sensors that detect marine life signatures and activating low‑power electromagnetic fields, the fins can create a localized deterrent zone, while built‑in LEDs improve visibility in low‑light conditions, addressing two key risk factors simultaneously.

The project’s manufacturing approach leverages the latest in composite lay‑up and additive manufacturing. Using automated deposition techniques, engineers can embed electronic modules directly into the carbon‑fiber matrix, ensuring structural integrity and reducing assembly steps. This convergence of materials science and electronics not only shortens time‑to‑prototype but also opens pathways for scalable production of other smart sporting goods. The involvement of UNSW’s sensor research team and the University of Wollongong’s composites expertise ensures that the fins meet rigorous marine durability standards while remaining lightweight.

Beyond safety, the initiative signals a strategic shift for Australia’s composites industry. Commercialising smart surfboard fins could generate new revenue streams, stimulate high‑skill manufacturing jobs, and reinforce the nation’s reputation for cutting‑edge marine technology. As global surf markets seek differentiated products, Australia’s early mover advantage may translate into export growth, attracting further investment into research hubs like the ACM CRC. In the longer term, the embedded‑technology platform could be adapted for other marine applications, amplifying the economic impact of this pioneering effort.
