<p><br /> A great white shark has been filmed attacking a fishing boat off the coast of Western Australia.<br /> </p><p><br /> The shark, which measured about five metres in length (16.4ft), circled the small boat, then threatened to capsize it by attacking the outboard motor.<br /> </p><p><br /> The three fishermen on board were not hurt and made a quick escape from the area, near the town of Busselton.<br /> </p><p><br /> Two of them had been swimming in the same spot about an hour earlier, according to local reports.<br /> </p><p><br /> Fisherman Mark Kik said the predator "kind of circled us quite a number of times, then it looked as though it was taking off, so it took off in the distance".<br /> </p><p><br /> "But within a short period, it was back again and circled around the boat again and then did a very quick U-turn and that's when it grabbed the motor," he added.<br /> </p>
