Roy Billing, who plays Senior Sergeant Graeme Sinclair, says the policing work is derived from extensive research and writers talking to a lot of cops.
"As an actor the first thing you look at is the script and this was good, so I think it's going to be a little bit different from the normal cop show," he says.
"There's a Local Area Command in Maroubra, one at Rose Hill. This is a sort of fictitious Eastern suburbs one. You've got you hierarchy with your head cop. I'm the grumpy old senior sergeant who never made it up through the ranks like he thought he should have. Promotion is not on seniority, it's on ability. Then you've got your young cops and new rookies."
With a mix of both detectives and probationary constables the show juggles both serious crime cases and lighter crimes encountered by young cops on the beat. The show will also touch upon some shades of grey for its central characters.
"The characters seem really interesting," says Billing. "They're not squeaky, clean cops. They're not corrupt or anything but they've got little personality things. They read very real, so that's interesting. It's not a country town that's the crime capital of the world, it's actually set in a big city."
Gary Sweet plays the station boss, the superior to Billing's Sgt Sinclair. But the two don't always see eye to eye.
"We've probably gone through police school together but he is further up the ranks so there's a little bit of tension there.
"My character gets confronted with something that happens to him and, like a Coen Brothers' movie, he makes a decision which dictates what happens to him through the rest of the series. Had he made a different decision it would have been a totally different story.
"But he makes a decision that there's no going back on."
