Ten NSW SES Alpine Search and Rescue Unit members joined the search for the missing hiker on Saturday, 12 September, alongside NSW Police, PolAir, Rural Fire Service, Police Rescue Squad, and National Parks and Wildlife Service.
The man was reported missing by family, who knew of his plans and expected him to return nine days after he started his back country trek.
The NSW SES members camped overnight on the snow in Kosciuszko National Park, before locating the hiker safe near Valentine's Hut on Sunday, 14 September.
NSW SES Snowy Monaro Local Commander, Chief Inspector Malika Bailey said the team was taking part in an alpine search and rescue assessment with new recruits when a "no-duff" call came over the radio.
"We got to the top of the mountain when we received the call about the missing hiker. We had to very quickly switch our hats from assessment training to operational response," Chief Inspector Bailey said.
"New members were teamed up with a senior leader and we made a plan to respond; we had three snow mobiles, three members in the side-by-side, two in another team and two supporting Police at the Incident Command Centre.
"Conditions were difficult due to the melting spring snow, but we're thrilled to have had a happy ending. We always want the person to be found safe and well."
Also witnessing the mission was NSW SES Commissioner, Mike Wassing AFSM, who was joining the alpine search and rescue team for the assessment day.
"The leadership of Malika and the team, and the seamless collaboration between Police and other agencies was impressive to witness," Commissioner Wassing said.
"I'm extremely proud of our NSW SES alpine volunteers, who combined their exceptional skills and local knowledge to achieve the successful outcome."
With roughly a month left of snow season, Chief Inspector Bailey urged skiers and hikers to be prepared when heading out in the region.
"We encourage you to log your trip by filling out a Trip Intention Form and make sure your loved ones know where you're going and when you'll be returning," Chief Inspector Bailey said.
"It's also important to hire a Personal Locator Beacon for free from National Parks and Wildlife Service Visitor Centres, to give you the greatest chance of being found safely."
