Unexpected spring snow has caused livestock losses in Bungendore, New South Wales just outside Canberra.
The most vulnerable animals bore the brunt of the cold weather, with veterinarian Michael McCormack saying the area has seen a significant loss of young lambs.
"Merino sheep are not very good mothers unfortunately," he said.
"If they're comfortable they don't necessarily take their babies to shelter.
"We've also had reports of adult sheep that have recently been shorn that have succumbed last night.
"They're just not used to the cold weather and that shock of having no wool and all of sudden being exposed."
But even surviving lambs face an uncertain future with many still suffering from hypothermia.
Essential Energy NSW staff working at Hoskinstown Road near Bungendore took it upon themselves to save one lucky lamb, taking her to Bungendore Veterinary Clinic.
Veterinarians are trying to regulate her body temperature, but say she is not out of the woods just yet.
"Dying of hypothermia is pretty awful and some of these guys would've suffered pretty awfully last night," Mr McCormack said.
