Tasmania's air rescue helicopter was kept busy overnight with two emergency medical evacuations.
About 7pm yesterday, Tasmania Police search and rescue were called to help a 29-year-old French man who had become ill on the Dove Lake track at Cradle Mountain.
A search and rescue member attended the man initially, but he could not be moved to due to his deteriorating condition.
The Westpac Rescue Helicopter was then called to airlift the man to the Launceston General Hospital about 10.20pm.
He was listed in a stable condition last night.
Then about 12.30am while on route back to Hobart, the helicopter was diverted to Rosebery on the state's West Coast to medivac a 61-year-old Rosebery woman, who was believed to be suffering a serious case of anaphylaxis.
The woman was also airlifted to the Launceston General Hospital where she was listed in a stable condition.
The helicopter finally returned to its base in Hobart about 5.30am this morning.
