Marine Pingers

Date: 1/8/2011

Cutting-edge Queensland technology which prevents whales and other marine life from becoming trapped in shark nets will be taken to the world. The $150 ‘marine pingers’ were added to Queensland shark nets last year. They emit a low-frequency beeping sound which lets whales know to keep their distance. Last year only one whale became trapped in the nets and was quickly released. Variations of the device have been in existence around the world for the past 15 years but the success rate of the new model has been much better and is attracting interest from interstate and overseas.
