As far as the actual crossing goes Im still researching and plan on speaking to some friends soon who have done it a couple of times for their thoughts, so I dodnt have any input to offer there, but for us leaving from Tassie or Port Melbourne, what would work for us is to make our way to Birdsville via a couple of the corners and meet the QLD and NSW people there I guess?
We would also only be looking at this trip as only being about a 2 week or so holiday. So I guess a few days getting up there, 4 nights or whatever is decided to cross one way and then a few days getting back.
We have done the western side of the simpson just recently and a couple of years ago so there is not a lot more we would want to spend too much time doing once crossed. I am not sure at this stage if we would go back across, so we would most likely just head back home once everyone else departs to return.
I can recommend going out to Old Andado Station and obviously Mt Dare pub once on the Western side.
More to follow as info comes to hand.
