An Indonesian fishing vessel and its crew of eight men were apprehended 175 nautical miles off the coast of Darwin on March 15, suspected of illegally fishing in Australian waters, the Australian government said.   Maritime Border Command (MBC), a multi-agency task force within the Australian Border Force (ABF), working in cooperation with the Australian Fisheries Management Authority (AFMA) apprehended the crew and brought them to Darwin.   The vessel was originally sighted by an ABF surveillance aircraft on March 15. Officers subsequently observed the men fishing and hauling live shark on to the deck of the vessel, according to the Australian government.   HMAS Pirie intercepted and boarded the vessel at sea. On the recommendation of AFMA, Pirie attempted to escort the vessel to Darwin for further investigation.   Due to the unfavorable sea conditions and the unseaworthiness of the fishing boat, the vessel began taking on a significant amount of water. Despite the best efforts of officers to assist, the vessel sank overnight.   The Indonesian crew were safely brought aboard Pirie before being taken to Darwin by HMAS Maitland for processing.   AFMA is investigating for breaches of the Australian Fisheries Management Act 1991 [...]
