A spate of shark attacks in a town north of Sydney is keeping many locals from swimming at sea, prompting the state government to fund an innovative 'eco barrier' to keep killer sharks away from people. While there is no agreement on the best approach to prevention, state governments along the more than 30,000-kilometre Australian mainland coastline have decided to adopt different measures.
Drum lines, where baited hooks are attached to floating barrels positioned a set distance off beaches, are deployed to catch sharks in Queensland. Some are collected and released elsewhere, many die on the hooks. The state also uses nets, which entangle them, causing them to drown. Conservationists have heavily criticised both measures and point out they also result in the death of other marine life.
