Mafia activity has been known to exist in Australia’s southern states for decades. Many however would not know that in the 1920s and 1930s Queensland had its very own Mafia. Known as the Black Hand they were every bit as dangerous as their southern counterparts. This group of migrant Italian cane field workers was full of extortionists, thieves, pimps, rapists and cold-blooded murderers. Four of these men would end up in Boggo Road Gaol.
