Our ranger team at East Alligator and Office of the Chief Remote Pilot were out detecting crocodiles and mapping the river bed at Cahills Crossing with a small boat and sonar when things took an unexpected turn... a few curious crocodiles started following it around!🐊 We think the sound and vibrations from the motor and propellers caught their attention, but we've never seen behaviour quite like this before! Fortunately, the boat lived up to its name... Sonar Ya Later. 😂 When visiting Cahills
