Underbelly: Badness, the fifth series of the Nine Network crime drama series Underbelly, originally aired from 13 August 2012 to 1 October 2012. It is an eight-part series detailing real events that occurred in Sydney between 2001 and 2012. The series began its production in early 2012 and towards the middle of the year filming eventually commenced. A teaser clip for the series was released by the Nine Network indicating the core cast of the series. Caroline Craig returns to narrate the series for a fifth time. It was the first season of the franchise not to have 13 episodes.
The fifth season of Underbelly depicted the criminal activities of recently convicted Australian kidnapper, murderer and drug-dealer Anthony Perish's (aka "Rooster") criminal activities around the Sydney suburb of Lindfield and adjacent areas and how the New South Wales Police 'Strike Force Tuno' finally apprehended him after almost a decade of intensive surveillance and informant information.
Anthony "Rooster" Perish would never have been caught if it was not for the dedication and perseverance of New South Wales police officer Det. Insp. Gary Jubelin. The series covers the scope and breadth of homicide, kidnapping, firearm offences and drug dealing committed under the direction of Anthony Perish, his brother Andrew Perish, various other criminal associates and several criminal Australian "motorcycle clubs."

Andrew Perish tracks down Decker and forces him to rejoin the Perish gang, while the Perish brothers and Dokic visit Gold Coast entertainment venues maintained by Perish's laundered drug money. However, the New South Wales and Australian Federal Police become aware of the new relationship between Dokic and the Perish gang, although Dokic is initially oblivious to Perish's real identity until subpoenaed to appear before the AFP, where he professes ignorance. Perish becomes increasingly paranoid and intimidating, fearing that Dokic will betray him. Ultimately, Perish orders Decker to go to extreme lengths to prove his loyalty to "The Company", culminating in the murder of Dokic's wife and son- although Decker is haunted by what he has been forced to do. Dokic discloses all he knows to Jubelin, Browne and the others and despite the inadequate primary content of his information, it is enough to formally reactivate Task Force Tuno. Camille comes face-to-face with Perish, unbeknownst to her quarry, in countryside Mudgee.|

Meanwhile, Jubelin and Browne meet Willy Strong, a pub and nightclub bouncer who knows Decker. Anthony Perish approaches Decker at the latter's wedding with a new assignment. Suspecting that another Perish gang underworld assassination is underway, Jubelin and Browne tail Decker through Northern New South Wales and Queensland to prevent another execution. However it turns out to be a bagdrop to Anthony Perish. Back in Sydney, however, there is a DNA breakthrough- which means that Decker has now become conclusively linked to the Falconer murder, and two other Perish gang members, Vito Russo and Michael Christiansen, are also identified by a reactivated Task Force Tuno.

|Unaware he is under police surveillance, Decker juggles two different hit-man contracts with the impending birth of his baby. He is forced to delegate responsibility for one such task to another Perish gang member, bodybuilder and steroid abuser, Michael Christensen. Christensen lures Peter Elliot, a corrupt business person and associate of Melbourne's Moran criminal family, to a deserted property, shooting him dead. Unfortunately for Christiansen, he is less than diligent in disposing of possible forensic blood and DNA traces from the crime scene, and New South Wales State Policelocate the box in which Christiansen stored his victim's body, dumped at sea. The reactivated Strike Force Tuno has been keeping Christiansen's storage facility under surveillance since its discovery and this paid dividends in his rapid apprehension. In return for leniency, Christiansen adds further information to Dokic and O'Rourke's prior affidavits about the Perish gang. Angry at Decker's mainstream priorities, Perish arranges a meeting with Decker to discuss the delegated and bungled Elliott hit, and Strike Force Tuno are finally able to swoop down and arrest Anthony Perish and Decker as they pull guns on one another. But does Tuno have enough information to prove Anthony Perish's responsibility for Terry Falconer's abduction and murder? Meanwhile, Gary Jubelin's relationship with Tracy is placed under severe strain as he closes in on Perish and his gang.|

|Despite Anthony's arrest, the case against the Perish gang appears to be doomed to end in minor manslaughter convictions, as the Perish brothers and accomplice Matt (Muzz) Lawton are tried for murder and conspiracy to murder. Anthony's defence counsel advocates that he plead guilty to manslaughter, but not murder. Within Tuno, there are anxieties about whether they have amassed sufficient evidence now to potentially convict Anthony and Andrew Perish and Matthew Lawton of murder per se, and matters are complicated by Camille's disclosure that she is now battling cancer. Tragically, although her meticulous communication work was essential to the establishment of interception and surveillance in the context of the Perish gang's eventual apprehension, Camille dies from her cancer during the course of the trial and is unable to hear the verdict that she so assiduously facilitated. Tuno uses surveillance wiretaps and relies on evidence from Frank O'Rourke and Ben Dokic, and a new prosecution counsel highlights Perish's methodical dismemberment of Tony Falconer's body. While Decker vacillates, O'Rourke delivers enough evidence to lead to the conviction of Anthony and Andrew Perish for conspiracy to murder and murder, and Matt Lawton for murder. At trial's end, Tuno celebrates its triumph, commemorating Camille's contribution to the final outcome in her memory. A footnote remarks that the Perish brothers are currently appealing the recent verdict of murder and conspiracy to murder.|
