AI robotics restore Australia’s Great Barrier Reef

December 02, 2025

Australian researchers have begun trialing a cutting-edge robotic system designed to accelerate the recovery of Great Barrier Reef areas severely affected by repeated coral bleaching.

Led by the Australian Institute of Marine Science (AIMS) in partnership with the Reef Restoration and Adaptation Program (RRAP), the project merges decades of marine-ecosystem research with new breakthroughs in marine robotics, automation, and artificial intelligence. The goal: to rapidly and accurately place juvenile corals in reef zones where survival rates are highest.

Automation targets large-scale coral restoration

The new technology, called the Deployment Guidance System (DGS), is being engineered to strategically position hundreds of thousands of lab-reared young corals onto the seafloor. These corals are grown in aquaculture facilities and later attached to specialized ceramic devices that protect them during their earliest stages of life.

Building on years of innovation—such as coral-seeding tools, refined larval-rearing methods, and collaborations with local communities—the DGS aims to take restoration efforts to a level previously impossible to achieve manually.

How the deployment guidance system works

The DGS unites data modeling, real-time sensors, on-board cameras, and AI to locate ideal microhabitats across vast sections of reef. A computer model identifies high-potential restoration zones, and once a vessel reaches these GPS-targeted points, the system analyzes the seafloor live.

AI then signals the exact moment to release the coral-seeding devices, ensuring each lands within a precise radius of suitable terrain—a level of accuracy extremely difficult for human divers or operators to achieve at scale.

Dr. Ben Moshirian, AIMS project engineer, emphasizes that the DGS is “a fusion of multiple technologies working in sequence to maximize coral-seeding success,” ensuring that each device is “placed safely and accurately in predetermined locations.”

Boosting, not replacing, human restoration efforts

Though autonomous operation is a major objective, AIMS stresses that the DGS is designed to support human restoration teams, not replace them. The system offers auto-navigation similar to an autopilot and can deploy devices on its own, but crews may also revisit tagged locations manually.

The technology’s built-in geo-tagging enables scientists to monitor coral development over time with exact precision, simplifying long-term ecological assessments.

To make sound placement decisions, the DGS draws from five years of RRAP research, including data from Modelling and Decision Support, EcoRRAP, and Coral Aquaculture and Deployment teams. Its AI components were co-developed with Queensland University of Technology.

Real-world testing underway

Field trials are currently being carried out using 5-metre crewed vessels in inshore waters as well as smaller boats commonly operated on the outer reef. These tests help researchers evaluate:

• System stability in varying ocean conditions

• Optimal hardware layout and onboard space requirements

• Accuracy of coral placement in diverse seafloor environments

Future iterations may be deployed on autonomous surface vessels (ASVs), allowing coral-seeding missions to scale dramatically without requiring large research ships.

Dr. Moshirian highlights the human-machine synergy at the heart of the initiative:
“This technology isn’t about replacing people—it’s about empowering them. By working alongside machines, we can achieve restoration at a scale that was once out of reach.”

He also noted the extensive collaboration behind the project:
“The true innovation comes from bringing experts across so many fields together with a shared purpose.”

Expanding opportunities for reef stewardship

If the system proves effective, it could open the door for a wider range of ocean users—such as Traditional Owner groups, tourism operators, and small maritime businesses—to participate in reef-restoration missions without requiring specialized research vessels.

By scaling coral deployment and making restoration more accessible, the DGS may become a critical tool in protecting one of the world’s most iconic natural wonders.
