Garry Thomas-George Gray, 32, pleaded guilty to supplying a prohibited drug when he appeared via video link in Goulburn Local Court on Wednesday last week.

Court documents state that at 1.45pm on September 28 last year, police were patrolling the Hume Highway near Penrose when they observed a silver Peugeot hatchback driven by Gray travelling south.

Police travelled behind the car and noticed it reduced its speed considerably under 100km/h in a 110km/h zone.

They pulled the vehicle over to randomly breath test the driver, which proved negative. There was also one passenger.

Gray appeared nervous and police conducted a search of the car, which revealed a roll of black duct tape under the front passenger seat.

They found a small package wrapped in black duct tape.

They also noticed loose granules of what they believed to be ice on the front passenger seat.

Police tore away some of the duct tape and found a clear plastic bag containing a considerable amount of ice.

Police arrested both of the occupants and took them to Goulburn Police Station.

Other court news:

The weight of the ice was 67.91g, which had an estimated street value of about $20,000.

In court, Gray's solicitor said a positive sentence assessment report showed the potential for his client's rehabilitation.

"Prior to these offences, he did well for six months and he got employment," the solicitor said.

"He totally accepts his responsibility for the charge and pleads guilty, but the drugs were not his.

"He was paid 2g of ice to drive to Sydney and collect the drugs and drive back to Wagga Wagga with them.

"The quantity involved is quite substantial but it is tempered by his role in it."

Magistrate Geraldine Beattie said it was a "huge amount" of the drug, considering 3g is a trafficable quantity.

"This is 20 times that amount, with a street value of $20,000," she said.

"If this had not been intercepted, that huge amount of drugs would have affected that community and what people do to get it," Ms Beattie said.

"The only sentence I can you give is full-time custody."

Gray was given a non-parole period of nine months.
