Five emergency level fires burning near the famous apple producing town of Batlow were at risk of merging on Saturday night.

The fires, at the northern end of the evacuated Kosciuszko National Park, included the Dunns Rd fire, the fires at Adaminaby Complex and Green Valley, Talmalmo.

The fires - which already burned 388,560ha on Saturday - were edging closer to the already merged fires at East Ournie Creek and Doubtful Gap Trail.
