A capsized boat off Thursday Island has left its crew clinging to a channel marker overnight until they were rescued by helicopter on Monday.

The four men - aged 51, 38, 21 and 16 - set off from Seisia Wharf at 3 o’clock on Sunday afternoon, but authorities were called when they hadn’t arrived home later that evening.

Police believe the foursome had been stranded for 13 hours before their rescue.
