The woman driver allegedly was so nervous that she had to put a hand on her leg to stop it shaking.

These were the clues to quick-thinking Albury police yesterday netting a $122,400 drug haul.

A search of the innocuous-looking white sedan pulled over at Little Billabong, north of Holbrook, allegedly uncovering 15 kilograms of cannabis in shopping bags in the boot.

Police said the street value of the drugs, if sold in one-kilogram lots, would be $122,400.

Yesterday afternoon a Sydney woman, 50, and Canberra man, 33, were charged with possessing a prohibited drug and supplying an indictable quantity of cannabis.

Another passenger sleeping under a doona in the back seat when the Toyota Aurion was stopped about 11am, was released without being charged.

The car was impounded and a forensic team was called in for further examination.

Acting Insp Chris Wallace said yesterday the highway was a main thoroughfare for drugs travelling between Sydney and Melbourne.

He praised the actions of the quick-thinking police.

“It wasn’t a targeted operation today but we do have targeted operations from time to time,” he said.

“But we have good police here in Albury.

“The highway patrol are out there every day, not only combating people who speed and put others at risk but detecting drugs as are detectives and general duties police.”

Insp Wallace said the vehicle was registered in NSW but unlike recent major drug busts was not a hire car.

In May a car stopped in the main street of Holbrook was found to have $3 million worth of high-grade “ice” in the boot

A month earlier, a hire car stopped near Wodonga was found to be carrying $2 million in methamphetamine.

At the same time, officers on both sides of the border seized more than 1400 ecstasy pills, again from cars on the highway and stopping on their interstate journey in Albury.
