Maybe not quite the centre, but we have 3½ weeks and we have enough water for 10 days, actually 15 days, but with the heat we are conservative.
Certainly outback NSW and up into QLD or over to the top of SA, possibly hanging around somewhere that suits us. We have a camper that is solar powered for everything permanently and gas for cooking. Gas lasts about 3 months.
View cameras use no power.
Do you know of anyone coming up from Melbourne that could take a kit up? We leave next week and get back for work on the 17th of January.
We will have someone in the house, but they haven't a clue about photography.
