“Sixteen of the Redhead beach shark sightings comprised sharks of two metres or larger, 10 of which were identified as bull sharks and one as a white shark,” the spokeswoman said.
The trial at Redhead was expanded for the school holidays after a drone found a three-metre great white shark among surfers in mid-December.
Drones scanned the Redhead surf most mornings, and their operators’ tip-offs prompted lifeguards to clear the surf or close the beach several times.
A video released by Primary Industries shows a bull shark within 15 metres of a jet-ski rider off Redhead, another bull shark 25 metres from a board rider, as well as hammerhead and whaler sharks close to shore.
It also confirms Redhead as a habitat for turtles, cownose rays and fairy penguins.
The drone trial was declared a success by Primary Industries Minister Niall Blair, whose department issued a release titled “Saving lives with eyes in the sky”.
