White Collar Blue is an Australian television series made by Knapman Wyld Television for Network Ten from 2002 to 2003.

Starring Peter O'Brien as Joe Hill and Freya Stafford as Harriet Walker, the series dealt with a division of the police force working in the city of Sydney and the personal and professional tensions affecting their work and lives.

In the pilot episode, Harriet is introduced as the new face to Kingsway station, transferring from the "White Collar" federal police to the "Blue Collar" New South Wales Police. Throughout the series Harriet must deal not only with her husband's brutal murder and the revelation of his adultery, but with learning to adjust and fit into her new surroundings.

Joe is Harriet's new partner, and isn't exactly welcoming to her as an addition to the team. With two daughters from previous marriages, Joe needs to juggle his homelife, his dedication to the job and his relationship with Nicole Brown, played by Jodie Dry.

The other cops at the station are Ted Hudson, played by Richard Carter, Sophia Marinkovitch (Brooke Satchwell) and Theo Rahme (Don Hany), and each have their own secrets and problems to deal with.

The series was cancelled after two seasons; however, it can be found on cable TV both in Australia and overseas (notably in Canada and New Zealand).
