Falls Creek to Wallaces hut is a decent day on XC skis. The reason I have not made it that far is the snow simply ran out after Langford Gap hut, each time I got that far. When the snow cover is good the FC resort grooms it for skate skiing all the way to Wallaces hut and to Cope hut. Skate skiers are fast and VERY fit and travel faster than I do on pattern base classic skis and BC XC skis. I can still ski 20 kms in a day but it is certain that after a shower and a meal I will sleep soundly that night following such a ski day.
https://www.ski.com.au/xf/threads/falls ... -20.87973/Camping in the snow at JB Plain is good but you will have to melt snow for water or BYO water and BYO firewood for the hut there. Parking can become busy there on weekends.
Dinner Plain has good XC ski trails . Some can become icy esp. the one that sits in the shade and goes around and down past the ski lift POMA run. Going up it Herringbone style could better if it is icy.
Getting lessons is important for XC skiing. Get the right skills and habits from the outset. Falls Creek offers lessons in more normal times at Windy Corner Nordic ski centre without the plague complicating things.
Lake Mtn. is where I started XC skiing and they have lessons there in season , ditto for Mt. Stirling .
Mt. Buffalo has a X C ski school which operates when there is sufficient snow at Dingo Dell & Cresta. Their details can be found on the WWW. The rates are good but you have to rent the gear from Bright, Myrtleford or Porpunkah.
You can rent XC ski gear at Dinner plain or from Omeo too.
As already has been observed , photos with snow and huts etc. look good without needing 1 metre of packed down skiable cover.
I went out to Craig's hut on snow shoes solo one winter and there was full cover from the Mt. Stirling summit area all the way to Craig's hut. It was foggy , cold and felt remote . If anything bad happened then it would have been up to me to get myself out of trouble because the ski patrol do not go there.
Falls Creek ski patrol do patrol the terrain outside the resort but only as far as Watch bed creek AFAIK and have seen.
I have skied out to Edmondson's hut and back to Falls Creek in a day in early spring and that was memorable and scenic.
https://www.ski.com.au/xf/threads/falls ... ser.85813/Back country activities in the snow should be approached cautiously & with experienced people accompanying you if you are new to this activity. You are in a cold, white and often windy environment which is nothing like January bushwalking.
