00:33:34.320 including in Australia, and this has resulted in a lot of 631 00:33:34.400 --> 00:33:37.640 interest in the devices to try to reduce those risks. 632 00:33:47.240 --> 00:33:49.680 HEMSWORTH (off-screen): The team have sailed to the Neptune Islands, 633 00:33:49.760 --> 00:33:52.120 a hot spot for great whites. 634 00:33:53.480 --> 00:33:56.280 The sharks come here to prey on

The idea behind these electric field based deterrents is that 643 00:34:20.640 --> 00:34:23.520 they will produce such a strong pulse, 644 00:34:23.600 --> 00:34:27.560 that it will overwhelm this sensory organ and make the 645 00:34:27.640 --> 00:34:29.760 shark physically move away from the source. 646 00:34:31.640 --> 00:34:35.240 HEMSWORTH (off-screen): The aim is to develop a safer
