Patrol Boat sailors say their job is the best in the Navy. A small boat and its crew facing real dangers not just war games. There are plenty of examples of those dangers in the 4th explosive series of SEA PATROL. The crew of the HMAS Hammersley is back on duty cruising Australias tropical north from the Great Barrier Reef and through the waters of the Torres Strait. With 24 sailors from every walk of life, of every age and temperament, life on board can be a pressure cooker that can bring out the best, and sometimes the worst in all of them man and woman alike.
