Innovative drone mapping research – a significant step in Great Barrier Reef site stewardship

31st of July 2025

An extreme low tide of just 0.2 metres combined with an innovative drone mapping research project has given us a unique opportunity to see the stunning Agincourt Reef 3 from a new perspective. The extraordinary low tide vision has also highlighted a thriving and vital ecosystem.

An innovative research project utilising aerial drone technology for mapping, monitoring and 3D modelling represents a significant step forward in Great Barrier Reef site stewardship, and future conservation measures at a premier tourism location.

Quicksilver’s Reef Biosearch team of marine biologists have been conducting research into the ecological composition and intricate structure of the reef surrounding Quicksilver’s Agincourt Reef pontoon - 72 km northeast of Port Douglas and located at the very edge of the Continental Shelf.

“By using drone technology, our aim has been to map out the reef and use this data and high-resolution imagery, coupled with in-water validation, to accurately document coral coverage within an approximate 20,000 m² area,” said lead researcher and Quicksilver marine biologist Fern Trent.

“Launching the drone over several days, including on one of the lowest tides of the year of just 0.2 metres, meant that a lot of the corals and clams were above the surface of the water. It’s providing a great opportunity for us to learn more about the reef, including for example, the location of the giant clams and unique micro habitats within our general snorkelling area.”

The high-resolution photographic data and tangible outputs such as 3D modelling and maps will also enhance visitor experiences – providing guests with a more informed snorkel experience and where to discover, for example, clownfish and other unique habitats. Additionally, it will provide a robust spatial framework for ongoing biological research and conservation efforts.

The research project commenced in April 2025 and as it progresses, the insights gained will be instrumental in ensuring the long-term health and resilience of the reef for future generations. 

Quicksilver Group Compliance and Environment Manager, Phil Coulthard said, “Quicksilver has a site stewardship commitment that extends more than 40 years at Agincourt Reef. Combining this effort with the Reef Authority’s Tourism Reef protection Initiative (TRPI) program over the past 4 years, Quicksilver has now established a comprehensive Site Stewardship Plan for Agincourt 3. 

“These plans are fundamentally based on site-specific research and monitoring programs coupled with innovative projects such as the use of drone imagery and GEONadir software for advanced reef mapping and impact assessment. These actions not only promote reef resilience at our own pontoon site, but also provides a wealth of data that the Reef Authority can use for management decisions, policy development, and adaptive management strategies for the entire Marine Park.”
