Same as I used in the FSJ.
A tarp, strapped to front and rear with a few occy straps, two poles to hold it up. a spare smaller tarp to act as a side wall if the wind or rain/snow is coming in sideways. Swag, esky, stubby holder (two in case one has a blow out) chair, and JetBoil stove. Freeze dried food, or snacks and the nearest high country pub. Waterproof matches or butane firelighter, firelighting cubes in case wood is wet, and the 023c Sthil.
Good for a week.
