The cancellation of the show in January 2006 made front-page headline news on nearly all of Australia's major daily newspapers, including "The Sydney Morning Herald" and Sydney's "The Daily Telegraph", Melbourne's "The Herald Sun" and "The Age", and Brisbane's "The Courier Mail".
Before her death in a car accident in season two, Tom's first wife Nell Croydon was mentioned in almost every episode but was never seen. In the episode of her death, her voice is heard and we see her left eye briefly in a photograph Tom touches before her funeral. Behind the scenes, John Wood who plays Tom thought the idea of Nell being talked of but never seen was hilarious, and called her "non-existant Nell". The episode of her death was rated one of the saddest moments in Australian television.
William McInnes and Martin Sacks were originally set to play characters called Nick Hasham and PJ Schultz, but shortly before production commenced, their surnames were swapped (to Nick Schultz and PJ Hasham) as it was felt they better suited the characters.
Six of the actors who later got recurring roles as police officers first appeared in the series in one-off guest spots as civilians. Peta Doodson, who became Insp Monica Draper, appeared as the wife of a council alderman, Tasma Walton, who became Const Dash McKinley, appeared as a 16-year-old schoolgirl, Terry Serio, who became Sgt Mick Doyle, appeared as a club bouncer and Jane Allsop, who became Const Jo Parrish appeared as a girl involved in a matchmaking scam.Marucs Eyre who became Det. Sgt. Paul Donald appeared as young criminal Luke Darcy's father and Samantha Tolj who became Const Kelly O'Rouke appeared multiple times before as teenager Louelle Nixon .
In the DVD audio commentary of season two, released in November 2005, John Wood and line producer David Clarke mention that Damian Walshe-Howling, who played Constable Adam Cooper from 1995-1998, was set to reprise his role in 2006. He came back to the show in the very last episode.
In one episode in season seven, a "Welcome to Mt. Thomas" sign is seen, and gives the town's population as approximately 6400. Undoubtedly this increased as the series went on. It was also shown through the earlier seasons that Mt. Thomas had both Coles and Safeway supermarkets.
The series was canceled in 2006 due to a sharp decline in ratings over the following seasons. At the shows peak it reached 3.5 million Australian viewers every night an episode would air. Over the course of a few years, ratings dropped to 1.2 million and was moved to an unpopular time slot on the 7 network scheduling from a Wednesday to Saturday, where it would struggle in the ratings with other hit crime show The Bill (1984) on ABC and Sports Night coverage of the AFL on Fox and TEN.
The series was one of the highest-rated and most-awarded programs in the history of Australian television, having won 5 Logie awards, it is equal as the most awarded show in Logies history with The Don Lane Show (1975).
