Alpine resorts in the snowy mountains are beginning to re-open, but back country areas in Kosciuszko National Park remain closed as fires continue to burn in the region.
Thredbo Resort was given the all clear to re-open by the NSW Rural Fire Service and National Parks Wildlife Service on Tuesday, after tourists were told to leave on January 3.
The resort says usual in-resort summer operations have resumed including the Kosciuszko Express Chair, Thredbo Mountain Bike Park, Thredbo Leisure Centre, and resort walking trails.
The scheduled Blues Festival on January 17 to 19 will also go ahead.
But access to all trails outside of Thredbo's boundaries will remain off limits until further notice, including the Mount Kosciuszko Summit Hike, Mount Townsend Hike, Alpine Lakes Hike, Dead Horse Gap Hike, The Ruins Hike and The Ramshead Hike.
Lake Crackenback resort will re-open its doors on Friday.
The RFS on Tuesday said there were fires burning in the remote Kosciuscko National Park, south of Mount Kosciuszko but conditions had eased.
Those fires were burning at advice alert level as of 5pm Tuesday.
Kosciuszko National Park remains closed with uncontained fires burning around Bogong Peaks Wilderness, Jagungal Wlderness, Colleman, Geegi, Pilot Wilderness and the Lower Snowy River (near the Victorian border).
The RFS said it was unlikely these fires would become contained in coming days and lightning and ember attacks may result in new fires.
"All visitors to Thredbo Village need to remain within the precinct boundaries," the RFS said.
Anyone needing to access parts of Perisher resort needed authorisation from National Parks and Wildlife Service.
Thredbo and Perisher resorts have so far escaped damage from the fires, but further north in Kosciuszko National Park Selwyn Snow Resort suffered extensive damage when the Dunns Road fire tore through on January 5.
That fire was burning at watch and act alert level as of 5pm Tuesday.
Fire activity was increasing in the Tumbarumba area while people in Gundagai and Goobarraganga were told to be alert to smoke and embers.
The Adaminaby Complex fire in the Bugtown area was also burning at a watch and act advice level as of 5pm Tuesday.
People in the areas of Shannons Flat, Yaouk, Adaminaby, Providence Portal, Anglers Reach, Old Adaminaby, Rocky Plain, Eucumbene Cove and surrounding area were advised to monitor conditions.
