Heavy snow caused an uncontrolled avalanche at Mount Hotham on Tuesday morning, with skiers urged not to stray from patrolled areas due to the heightened risk.
The avalanche happened about 11.30am, in the back country on the side of Mount Hotham summit.
There were no injuries to mountain staff or guests, an alpine resort spokeswoman said.
She said the mountain's ski patrol team performed daily controlled avalanche work, and had noted in Tuesday's snow report the "danger of sizeable wind slab avalanches at higher elevations.''
"Ski patrol attended the scene and assessed the avalanche, they ensured the area was clear," she said.
Mount Hotham ski patrol director Bill Barker said skiers should remain inside the resort's boundaries until the snow had stabilised.
"[Skiers should] remain inbounds where the skiing is awesome, and wait for the snowpack to stabilise in the back country before venturing out there," he said.
Hume police Inspector Paul Hargreaves said the avalanche was "quite significant" because it occurred in the resort boundary.
"The risk is present at the moment and reiterates the message that people need to stay out of those unpatrolled areas."
A Falls Creek spokeswoman said there had not been any uncontrolled avalanches in their back country this week.
"Our ski patrol is monitoring the situation before we get people out there. Advice is to ski on-piste and not go out of bounds," she said.
A heavy fall of 50 to 80 centimetres of snow was dumped across the Alpine region over the weekend.
Skiers reported blizzards, as high winds combined with the heavy snow dumps.
Bureau of Meteorology forecaster Beren Bradshaw said winds reached 90km/h in the region on Sunday.
The Falls Creek snow report named the event "Blizzard of Oz" and said Falls received 100 centimetres of snow on the weekend.
Chris Hocking took photos of cars buried in snow at Falls Creek on Sunday, and said one holiday-maker took more than an hour to dig his vehicle out of the resort's car park.
Overnight on Monday about nine centimetres of snow fell at Mount Hotham, and 15 centimetres at Falls Creek.
Roads around Mount Hotham were closed, including the Great Alpine Road, which reopened about 2.30pm.
VicRoads said Benambra-Corryong Road, between Nariel Valley and Benambra, and Omeo Highway, between Mitta Mitta and Glen Wills, remained closed on Tuesday afternoon.
