Check the snowcam out before you go...https://mtmawson.info/snow-cam/#!prettyPhoto
A couple of weeks time is getting into the middle of winter, although there hasn't been much snow accumulation yet.
There could be no snow / some snow / or backcountry skiing.
Usually we don't get to ski tour until more into August/Sept (if at all), but it could be a consideration - deep snow / icy where you would struggle without snowshoes or spikes etc.
Also keep in mind if the track is under half a metre of snow your only going to have a few snow poles to find your way.
Chances are there won't be much in the way of snow and it'll be fairly straight forward, but keep in mind it's a significantly harder undertaking in the snow pot holing the all way there and back.
I keep wanting to ski tour out to Field West, but we usually get out to the Tarn Shelf and the downhill runs from the top of the Rodway are too tempting and we end up playing around there.
It's unlikely to be like this, but it does happen.... but probably not this year or in the next couple of weeks the way things are going.
