NSW Police Intelligence lists “the main” Calabrian Mafia clans as “the Sergi family, Trimboli family, Romeo family” who are all “based predominantly in the Griffith area.
Only a very small number of members of these families are engaged in crime and there are many Italian families who share these common surnames who are not connected to the Calabrian Mafia.
“The criminal activities engaged in by this network have been engaged in for decades with a high level of success,” said one police assessment. Members of the network have occasionally been apprehended and imprisoned but, on the whole, internal wrangling appears to have exacted a higher toll, as family members are murdered not infrequently.”
A joint Four Corners/Fairfax Media lists cannabis growing and hydroponics amphetamine manufacture precursors as illicit businesses operating in the Griffith area. Sydney Bandidos, Batemans Bay Rebels and Canberra Rebels are listed as associates.
