More arrests are expected here and around the world after a three-year police operation stretching across Australia, the USA, Europe and Asia.
Federal police say the operation has led to the seizure of almost four-tonnes of drugs and the prevention of twenty-one murders.
Homes at Moolap, Werribee, Truganina, Tarneit and Point Cook have been raided as part of the operation.
More warrants have been executed at homes in regional Victoria including at Buninyong.
More than two-hundred people have been arrested in Australia alone.
