Overnight snowshoeing track in Kosciuszko NP needed

[Lyaksej]

Hey guys!
We are going to Kosciuszko NP in the end of July and want to make a 2-3 days track with 2 overnights in tent.
We want to walk in the snow (do not have skis nor snowshoes) . It would be the best if half of track is in the forest and another half in open space.

Please suggest something coz can't find any good snow track description on the web.
