The latest head of a country Victorian ice syndicate wasn't a brutish bikie or a wannabe gangster in an oversized suit, but a young woman who ruled the roost with slippery sophistication.

Ultimately, it all came undone for Jessica Fogarty, who on Tuesday was sentenced in the Wangaratta County Court to seven years in prison after pleading guilty to six charges, including commercial drug trafficking. But for four years before her September 2014 arrest, the now 26-year-old was queen of a syndicate that peddled millions of dollars in ice and cocaine across the north-east.

The Wangaratta-based Fogarty, allegedly alongside boyfriend Matthew Tymms, supplied drugs through connections in Melbourne and Sydney that she would on-sell to lower-level local dealers.

She rewarded loyal dealers with cut-throat prices, while those who owed her faced threats of violence from the enforcers who worked for her.
