Frank La Rosa, 46, was sentenced before Judge O’Connor in the Bathurst District Court on Thursday on charges of cultivating a prohibited plant greater than or equal to a commercial quantity, supplying a prohibited drug, possessing an unauthorised firearm and acquiring a firearm while subject to a prohibition order.

Further offences against La Rosa were taken into account on a Form 1.

La Rosa was also sentenced on two Commonwealth matters including possession of $14,350 in counterfeit currency.

La Rosa was arrested at his family’s Oberon property in August 2017 after an investigation by Strike Force Raptor into the cultivation and supply of cannabis.

Police executed a search warrant at the Oberon property where they uncovered sophisticated cannabis cultivation systems across four rooms of his house.

In each room officers found cannabis growing at a different stage of the growth cycle, which the Director of Public Prosecutions said indicated an ongoing supply process.

The crown prosecutor described the set-up as sophisticated with lights, air filtration systems and insulated ceilings and walls.

More than $14,000 in counterfeit currency was found at the house, along with a loaded single barrel shotgun.

A psychologist’s report tended to the court told how the robustly built La Rosa had been bullied at school over his weight and had gravitated towards delinquent peers.

It was through his work as a mechanic that he was recruited by the Comancheros.

However, the court heard after La Rosa was paroled for his role in a fatal bikie brawl at Sydney airport, he decided to make a change for the better and moved to Oberon.

La Rosa was jailed for a total term of four years and six months, with a non-parole period of two years and six months.

He will be eligible for parole on November 22, 2021.
