The men were among six people arrested by police on Thursday following a nine-month investigation by Strike Force Garnier, where police allege more than half a kilogram of methamphetamine and cash was seized.

Jacob Matthew Morrison, 25, of Suttor Street; Tony James Simmons, 31, of Rankin Street; Gregory Charles Campbell 61, of Upfold Street; and Aiden John Hartnett, 22, of Pacific Way, Bathurst were all refused bail following brief appearances before local court registrar Mark Nicholls on Friday.

Morrison was charged with supplying a prohibited drug on an ongoing basis, possessing a prohibited drug, and possessing or using a prohibited weapon. He will reappear before Bathurst Local Court on Monday, March 12.

Simmons was charged with supplying a prohibited drug (5.1g of methamphetamine), possessing a prohibited drug (4.1g of cannabis), resisting and hindering police, intentionally dealing with a prohibited statewide bio-security matter (an American corn snake) and wearing a police uniform while not police officer or special constable.

He did not apply for bail, which was refused. His matters will be back before the court on March 19.

Campbell, who made a release application which was denied, is charged with supplying a prohibited drug, not less than a large commercial quantity. He was refused bail and will reappear on Monday, March 12.

Hartnett, who also had a release application denied, is charged with supplying a prohibited drug (large commercial quantity), with police alleging he supplied 529.23 grams of methamphetamine between September 1, 2017 and March 8 this year.

A 20-year-old woman was also charged with participating in a criminal group and was granted conditional bail to appear at Bathurst Local Court on Monday, April 9.

A 24-year-old man was released pending further inquiries.

Chifley Police District Superintendent Paul McDonald said the arrests were the culmination of a nine-month investigation, and he expected more arrests to follow.

He said police are actively seeking another four to six people allegedly involved in the syndicate, which is alleged to have been operating in the district for a number of years.

He commended the work of all officers involved in the investigation.

“Seventy thousand hits of ice taken off the street, with a monetary value of $1.7 million -money which would have gone into the pockets of people profiting from the misery of others,” he said.

He urged anyone with information on drug supply to come forward.

“If you have any information about ice supply in NSW, whether it is in a country town or major city, please contact Crime Stoppers on 1800 333 000. Information can be left confidentially,” he said.
