Woman drowns after NT houseboat sinks A WOMAN has drowned after a houseboat sank on the Mary River, east of Darwin. Police attended just before 5pm (CST) after receiving reports that strong winds from a storm front tipped over one houseboat that was moored to another. Police believe the woman was trapped under water in the capsized vessel. Duty Superintendent Daniel Shean said members of the group dived in the water to recover her and began CPR. They then took the woman in a tinny to the boat ramp where they met police. Police continued resuscitation until paramedics arrived but the woman was unable to be revived. The other eleven members of the group are accounted for and safe. Police are investigating the incident on behalf of the coroner. The Mary River is about 100 kilometres east of Darwin.
