People have been advised to stay out of the water as Lauren O’Neill recovers from surgery after she was attacked by a shark in Sydney Harbour on Monday evening. The 29yo sustained a serious leg injury after being bitten by what experts reckon was a bull shark – she was swimming in the city’s eastern suburbs just before 8pm. Several passersby came to her aid, including “hero” vet Fiona Crago, who used bandages she had just bought to stop the bleeding until emergency services arrived. Shark attacks in Sydney Harbour are rare… The last one happened in 2009 when navy diver Paul de Gelder lost an arm and leg to a 3m bull shark during a counter-terrorism exercise – he now works as a conservationist for the species. Officials say warmer/cleaner waters have encouraged more sharks into the harbour, but the chances of another attack are “incredibly low”.
