Cutting edge detection and alert technology is set to be used to keep Douglas Shire locals and holidaymakers safe from crocs.

“The Department of Environment and Science (DES) is trialling the use of multi-beam sonar and deep-learning technology to automatically detect the presence of crocodiles in the Douglas Shire,” the Member for Cook Cynthia Lui said.

“This is the same technology used in the Western Australian SharkSmart program.

“Preliminary results are encouraging, with crocodile detection rates approaching 100 per cent during the latest trials.”

The technology is being trialled at Hartley’s Creek Crocodile Farm at Wangetti, with the trial to rollout further to sections of freshwater streams in the Far North, and as a mobile system from a boat early in the new financial year.

The Member for Cook said the trial is currently two years into a planned four-year project.

“So far the research team has completed trials demonstrating that the use of a combination of multi-beam sonar technology and ‘deep-learning' computer systems can reliably automatically detect and alert the presence of crocodiles in an area,” she said.

Douglas Shire Mayor Michael Kerr said it is exciting to see that modern technology can be used to assist in protecting residents and tourists from these ancient prehistoric creatures.

“Between drone technology, tracking methods and opportunities such as this we can build a confidence in allowing the usage of our beaches in these areas,” he said.

DES has also previously funded drone technology and an app where people can report croc sightings in real-time.

“In 2018, DES provided $105,000 to Surf Life Saving Queensland (SLSQ) to conduct drone-based crocodile monitoring of patrolled beaches in Far North Queensland, including at Four Mile Beach,” Ms Lui said.

“This was followed by the free QWildlife app which enables crocodile sightings to be reported in real-time. People can also use the app to check where crocodiles have been seen in the previous 30 - days and the whereabouts of any declared problem
crocodiles.”

Members of the public are encouraged to report crocodile sightings via the QWildlife app, by calling 1300 130 372 or via the DES website.

DES investigates all reports it receives and any crocodile that poses a threat to human safety is targeted for removal under the Queensland Crocodile Management Plan.
