Beach drones keep watch for holiday hazards Myall Coast Myall Coast - popup ad by News Of The Area - Modern Media - January 25, 2024 The warning sign visible on the beach. VIGILANT over the sea for the safety of all is a small but purposeful group of Unmanned Aerial Vehicle (UAV) pilots, working in conjunction with the Surf Life Savers (SLS) of NSW this holiday period. Beachgoers at Hawks Nest may have noticed the cabana erected away from the madding crowd, where the drone operators spend their seven-hour shifts in what could be called the best office in the world.

The drone, a nifty quadcopter with 1.5km range, never ventures farther than human sight, and its battery lasts around 20 minutes, according to Marcus, although the next upgrade will have double that. The drone also has a speaker siren, so it can be used to alert distant swimmers of any dangers in case of emergency. While Marcus wears the lifeguard colours, SLS NSW is keen to get more trained lifeguards into the pilot seat. By Thomas O’KEEFE Best office in the world? Marcus remote pilots, with local lifeguard Sam in training. The quadcopter drone and controller. The drone has a ‘chin’ camera and speaker on top to warn swimmers too far away.
