Sharks: Can technology replace the need for nets and drumlines?

If there was a shark in the water at your local beach, would you want to know about it before you dived in? "The committee is of the view that the available evidence about the effectiveness of lethal shark control measures used in New South Wales and Queensland does not warrant their continuation." On the app's map of the New South Wales and Western Australian coasts, dense clusters of shark fins show the location of potentially dangerous sharks that have been caught, tagged with a satellite tracker, then released. "The Department of Agriculture and Fisheries does not release dangerous sharks caught in the Queensland Shark Control Program," a Fisheries Queensland spokesperson said via email. "The Department monitors catch data for all species caught under its Shark Control Program … this is not a public alert system, rather an open data report."
