Meet the people who risk their lives to protect the world-famous waterway.

Iconic Sydney Harbour attracts more than 40 million visitors per year and covers 317 kilometres of shoreline. It’s the largest – and one of the busiest – natural harbours on the planet.

This series follows the struggles and triumphs of a dedicated group of workers tackling the mammoth logistical challenges to keep the harbour open every day of the year. They fight to maintain law and order, ensure massive construction projects stay on track, protect the delicate eco-system against poachers and keep congested shipping lanes clear of dangerous debris from accidents and fierce storms.

With unprecedented behind-the-scenes access, Sydney Harbour Patrol reveals a rare side to one of the world’s most beautiful cities.
