Victoria's Department of Environment, Land, Water and Planning (DELWP) has said a number of fires have begun converging in the past 24 hours.
The largest is in the Omeo region near the Alpine National Park.
Three fires joined there overnight to create a 6000 hectare fire, news.com.au reports.
The large inferno is now moving toward Cobungra, and could flare up as conditions worsen throughout the day.
A Defence Force spokeswoman confirmed aerial evacuations are currently taking place in the Omeo region.
Three Chinooks that can each carry between 16 and 25 passengers per evacuation are in use.
"Defence in the East Gippsland fire region has been assisting our emergency services with providing air support for moving of our firefighters and police into isolated communities, assisting with evacuation of personnel trapped or in isolated communities such as Mallacoota and several other small towns in that area, Cann River, Bruthen, et cetera.
"Where we can, we're providing as much air support to the services as possible subject to weather conditions and we'll continue to do that under the guidance and direction of the
emergency services and our teams are working closely together there. "
In the same briefing the incident controller for the Gippsland region confirmed that a crew of 60 US firefighters would arrive in the area this afternoon to assist fatigued local firefighters who have been battling severe blazes since New Year.
The firefighters would be assisting primarily in the Omeo Valley in East Gippsland.
While the conditions were mild this morning, the DELWP Gippsland warned against complacency.
"As the day progresses, and weather heats up – the risk will increase right across the region," the DELWP Gippsland said.
"The risk is still real in this area and the community needs to stay very much aware of conditions and relevant warnings.
"Further wind and weather changes are expected in the region by mid-afternoon."
Fires are also ravaging Kangaroo Island, where two people have now been confirmed dead.
South Australia Police confirmed the two deaths at a community meeting on Saturday morning, and police also confirmed it at a press conference around the same time.

Authorities are not aware of any other people missing on the island.
The Ravine Fire that has burned the western half of Kangaroo Island is now at a watch and act message but is burning out of control.
A bushfire advice message is in place for the eastern side of the island to ensure the public is aware of the uncontrolled bushfire to the west.

Authorities have confirmed that a man severely injured in a bushfire in November has died in hospital.
The 59-year-old was sheltering from a blaze inside a water tank on his property in Yarrowitch in the NSW Northern Tablelands region when he was found by a National Parks and Wildlife employee and airlifted to Port Macquarie Hospital.
He was then transferred to Royal North Shore Hospital in Sydney for treatment of severe burns.
He died there last Sunday, December 29, police announced overnight.
The death toll from NSW bushfires is now at 17.
