UNDERBELLY is a 13-part Australian television mini-series, retelling the real events of the 1995–2004 gangland war in Melbourne. The series depicts the key players in Melbourne's criminal underworld, including the Carlton Crew and their rival, Carl Williams. It uses the framework of the war waging within the underworld, and the war between the underworld and the Purana Task Force, to explore a complex array of individual stories and relationships. The series examines the kaleidoscopic nature of loyalty, love, revenge and pride when the normal and identifiable emotions of human attachment are moved from the context of social decency to social indecency.

The mini-series received numerous awards in the Australian Film Institute Awards in 2008, including best lead actor in a television drama, best lead actress in a television drama, the best supporting actor, the supporting actress, Best Television Drama Series and Best Direction in Television.
