Cairns is set to lead the way in wildlife safety innovation, with a local business developing a world-first buoy designed to detect crocodiles underwater using advanced sonar and Artificial Intelligence.
NorthWatch Technologies has been awarded $100,000 through the Queensland Government’s Private Sector Pathways (PSP) Challenge to bring their Croc Detection System (CDS-1) to life.
While crocodiles are a natural and protected part of Queensland’s ecosystems, their presence in popular waterways can pose serious risks to public safety. Currently, wildlife rangers rely heavily on community reports submitted through the QWildlife app, which helps track sightings and manage problem crocodiles.
The new CDS-1 buoy aims to take things a step further, using technology to detect crocodiles that may not be visible to the naked eye. Equipped with 24/7, 360-degree sonar coverage within a 50-metre radius, the buoy can:
-
Detect crocodiles underwater
-
Assess their size and threat level
-
Track their movements – even when they’re stationary
This innovation could become a game-changer for high-risk locations, such as boat ramps and swimming areas, where crocodiles are more likely to come into contact with people.
Over the next eight months, the prototype buoy will be designed and developed in Cairns, with the aim of proving its concept and paving the way for wider deployment across Queensland.
The Queensland Government operates a world-class crocodile management program that balances public safety with the conservation of crocodiles in their natural habitat. The addition of innovative detection systems like the CDS-1 buoy could strengthen this approach, empowering people to make safer choices when living and working in crocodile country.
Meanwhile, the community still plays an important role. The public is encouraged to continue reporting crocodile sightings via the QWildlife app or by calling 1300 130 372. Every report is investigated by wildlife rangers.
