Shark forces re-closure of WA beach THE beach where a surfer was killed by a suspected great white shark has been closed again after a shark sighting close to shore. A five-metre shark was spotted off the coast of Gracetown in Western Australia's South West on Tuesday afternoon, prompting rangers to erect beach closure signs from North Point to South Point. The Department of Fisheries has a vessel on the way to Gracetown and Surf Life Saving helicopter patrols are already underway. The beaches will remain closed for 24 hours - until 2pm (WST) on Wednesday - as a precautionary measure. Chris Boyd, 35, was surfing at the popular surf break Umbies off Gracetown when a suspected great white shark bounced off another surfer's board and attacked him on Saturday morning. An imminent threat order issued after the shark attack was rescinded on Monday night after the Department failed to catch a shark potentially responsible for the attack.
