Government officials and police representatives joined the Adelong community in celebrating the newfound security and peace of mind for the town.

Minister for Police and Emergency Services David Elliott attended the official opening at 91 Tumut Street, alongside Acting Assistant Commissioner Dean Smith, Riverina Police District Commander Superintendent Bob Noble, Member for Wagga Joe McGirr, and Snowy Valleys mayor James Hayes.

"There is a real sense of a new start today," Dr McGirr said.

He added that the new station was long-awaited and much needed to ensure the people of Adelong feel protected.

"The previous station had been there for 159 years, and while it wasn't showing all 159 years of age, it probably showed over 100," Dr McGirr said.

"It was located away from the main street too, and now they have a very modern building that's well signposted, well lit, and has a commanding presence when you come into town so it creates this impetus to safety."

Superintendent Noble added that the upgrade was a show of the government's commitment to regional NSW.

"These little towns often fear they'll lose some government amenities, but this well-over a million dollar investment is solid evidence of that commitment to the community," he said.

"The new facility is equipped with a public front counter, duty rooms, an interview room as well as a secure detainee area."

Mr Elliott said the $15.9 million Regional Small Police Station Program would support police and the local community.

"The NSW Government continues to deliver on its election commitment to invest in a police station infrastructure program to support the vital work of our police men and women," he said.

"The facility provides the resources and modern amenities for police to operate effectively in Adelong and its surrounds."

The station opening was also a day of recognition for two of the Riverina's long-serving police members.

Mr Elliot awarded Cootamundra's Frank Brown a national police medal celebrating his 30 years of diligent service to the NSW Police Force.

Wagga's District Manager Sharyn Peterson was also presented with a medal for her 15 years of ethical and diligent service.
