THREE men have appeared in Wagga Local Court after police seized $9 million worth of ice at Gundagai and $5.5 million worth of cannabis on a property near Young.

A police anti-drug operation months in the planning and execution culminated in the three south coast men appearing separately in Wagga Local Court for a total of four minutes today.

Luigi Gino Fato, 62, of East Lynne, is alleged to have directed a criminal group that included 40-year-old Hank Peter Pickett and 63-year-old John Sidney Finlayson, both of Malua Bay.

All have been charged with drug supply offences as well as being part of a criminal group.

Police said it would be alleged the men were involved in a major drug syndicate producing, distributing and selling commercial quantities of methamphetamine (ice) and cannabis throughout southern NSW.

The trio was stopped and arrested by police at the Dog on the Tuckerbox north of Gundagai about 9am on Wednesday.

It is alleged police found 9.5kg of ice with an estimated street value of $9 million in their vehicle.

Police subsequently executed search warrants at numerous locations around the state and allegedly found 2750 cannabis plants worth $5.5 million on a rural property at Crowther, near Young, and two pallets filled with shotgun cartridges and 60kg of gunpowder on a property in Wood Road, Yenda.

Raids were also conducted in Sydney and the ACT resulting in the arrest of four other men.

Fato and Pickett were represented in Wagga Local Court by duty solicitor Zac Tankard, while Finlayson was represented by Canberra solicitor, Kamy Saeedi.

Police prosecutor, Sergeant Kelly Huggett, said all three accused men should have their cases adjourned to Batemans Bay Local Court.

All three accused appeared wearing the clothes they were arrested in on Wednesday.

None applied for bail, although Mr Saeedi asked for Finlayson to face court again within a week so he can make a bail application then.

Fato and Pickett's cases were adjourned to Batemans Bay Local Court on February 24, while Finlayson will appear on February 20.

All three will appear in court via audi-visual link with a prison.

Four police officers involved in the drug bust were in court for today's appearances.
