SYDNEY — Two large sharks have been killed in Australia after a woman and a girl were attacked at a popular Great Barrier Reef tourist spot. ADVERTISEMENTDrum lines, which use baited hooks to catch the predators, ensnared two tiger sharks — one 11 feet long, a Fisheries Queensland spokesman said. This week’s incidents have revived debate about how best to reduce the risk of encounters between sharks and the growing number of people using the ocean for leisure. Many conservationists and marine scientists object to killing sharks, and insist that drum lines are a blunt instrument because they often catch other creatures. New South Wales, the country’s most populous state, has trialled non-lethal measures such as aerial drones to track sharks’ movements and “smart” drum lines that alert authorities to their presence.
