Only In Australia 19 - Shark Repellent

The video discusses a shark repellent device that attaches to a swimmer's ankle, emitting an electronic field to deter sharks by affecting their nervous system. It was inspired by anti-shark pods used in the 2000 Olympics. The repellent causes discomfort to sharks, escalating to muscle spasms as they approach. It has a range of 4-5 meters, weighs 450g, and lasts two hours. Alternative shark safety tips include swimming in groups and avoiding twilight hours. The video concludes by noting the rarity of shark attacks and the availability of repellents in Australia.
