I use purpose made steel snow pegs.
I have done a number of trips up Mt. FT and Mt. Bogong in atrocious white season weather leading groups with the VNPA and going over to camp at Fitzgerald's hut in fierce winter winds.Even the summit of Mt. Stirling can really be heavy going in bad white season weather.
What Explora says is true to some extent.
If you cannot stay warm and dry in terrible winter weather then you should reconsider your trip.
If your gear and habits / knowledge cannot match what nature throws at you above the tree line and in the tree line then reassess your trip.
The snow camping for newbies at JB Hut and at Mt. Stirling are the best ways to start IMHO.
Getting over the summit of Mt. Bogong to CC hut in snow and ice is the interesting bit.
I would start with Michell hut and wait for a weather window before proceeding any further past Michell hut & / or Granite flat spur junction .
Poo pooing the snow shoe options that one has as well as great ski touring options starting from Falls Creek and looking at the BHP for a snow shoe/ ski tour is not what I would be doing.
The BHP is my favourite place to bushwalk and Nordic ski tour.It is a place that inspired me to learn to ski.
I saw the people on skis while I was snow shoe trekking with an overnght pack and realized that skiing is more efficient and involves skills and fun that snow shoes don't offer.
If you don't want to pay or think ski resorts are soft boy thingy places then try the 12 km day loop from TBJ or head up from Big Hill to Bogong Jack Saddle with a view to visiting the Fainters in clear weather.
I have been up there in heavy fog. You cannot see anything and you could be anywhere.
The views of Mt. FT from the Fainters are excellent in clear weather.
Even going over the summit at Falls Creek can be interesting in heavy fog, snow and wind.
If that is not hard core enough for you then a trip to Antarctica is next .
A good wild winter snow shoe tour I did solo some years ago was The Bluff spur hut to Craig's hut for lunch and back.
That was a solid day and if things went wrong out there then there was NOBODY out there to assist you.
You need to know what you can and cannot do safely and what time you will be back. In white season I insist on being back at the car/ hut/ tent /base by 4 pm.
