Drone footage has captured images of 64,000 green turtles coming ashore in Far North Queensland to lay eggs. The green sea turtles are coming ashore on Raine Island, which is about 620 kilometres north-west of Cairns in the Great Barrier Reef, and is the world’s largest green sea turtle rookery. A research paper published on June 8 shows that using drones is now the best way to count the sea turtles.
