Locky63red, I am a jealous man right now. I didn't do the Mawson trail when I was in Oz. I did do the Snowy river area between Buchan and Jindabyne and that was fantastic. Spent about 3 days camping in the same spot.

You also brought up a good point. I like a big bag compared to four because it's all right there in one spot. Instead of having to unload the tent and bag from the top of the rack to access your rear panniers. My memory isn't the greatest so whatever I was looking for was usually in the last pannier.
