Australia's Mafia gangs

Inside Australia's Mafia gangs:
This week looks at how tight-knit mafia families have evolved from the 1930s to the 1990s and now, and how the Calabrian mafia's tight grip on a range of enterprises have been maintained in Australia.

GANGS OF OZ also takes a close look behind the scenes of some high-profile murders, how mafia figures have influenced politics throughout the years and how these "families" have maintained their strong position.

There's also the remarkable story of how fruit and veg trading become a potentially bloody business as a supermarket chain sought outside help to take on the high-profile rip-off merchants at a major market.
