Sydney Harbour Cops 1-1

The MAC prepares for Sydney Harbour's biggest night of the year, while officers face a sinking boat, a medical emergency and vessels taking on water, and crews train for an ocean rescue.

The Marine Area Command oversees an international fleet of warships on Sydney Harbour, while the Dive Unit heads to rural NSW to hunt for a missing gun in the turbulent waters of a surging river.

Police patrol dangerous waters from Botany Bay to Coffs Harbour, searching for a missing fisherman, before the Nemesis battles huge seas accompanying the Sydney to Hobart fleet down the NSW coast.
