We recently did the full traverse of the WAs. Had great weather and got through in 9 days pretty easily. Unfortunately I was hoping to head down the eastern Arthurs to Feda but my mate got the worst blisters I've ever seen so we headed out with 4 days worth of food still in our packs!
Anyway for 13 days on the track without a food drop my pack was 14.3kg. This includes everything and is not my base weight. We could have lowered the weight by another 1-2 kg if we tried hard. Full gear list if you're interested at http://mycampgear.com/2009/03/03/hiking ... ght-weight
We didn't skimp on a strong tent (ok we went way overboard by taking a bombshelter as we were expecting to share this 3 ways), or other stuff like PLB etc.
The biggest part of this I think was dehydrating all of our own food. I have allergies so the bought stuff isn't an option. I'll be writing up some of that with some video to come soon.
