Accused National Crime Authority bomber Domenic Perre has been jailed for his “central” role in a South Australian cannabis trafficking operation. District Court judge Rauf Soulio on Tuesday jailed Domenic Perre for seven years, six months, with a non-parole period of six years. Judge Soulio accepted that Perre had a “critical and senior” role in the operation. He detailed Perre’s history of drug offences, which included sentencing for involvement in the Hidden Valley cannabis crop operation in 1998. Perre pleaded guilty to three counts of trafficking in a large commercial quantity of a controlled drug and one count of possessing a silencer.
