We did the Major Mitchell over the weekend as an overnighter. We left a car at Jimmy creek, rode bikes on the main road back to Sheephills, stashed them and walked clockwise over Mt William and the plateau back to the car, camping at 1st Wannon.
I haven't done the walk before so I can't say how much it has changed but I thought I'd put up some pictures of the new track anyway. Basically the track looks untouched from Mt William down to Boundary gap, then there is a lot of new stonework up to the plateau with steps replacing any scrambling that was there. Then across the plateau there is a combination of boardwalks, stone paths, stepping stones, footpads and bare rock. The descent off the plateau is untouched with a steep rocky descent and some minor scrambling. From the helipad to Jimmy creek there are many, many new stone steps.
All the new work looks pretty stark, but the older sections blend well as the vegetation has returned.
There are no new platforms etc at the camp.
It's still not a beginners walk, with lots of eyes on-the-ground rough walking remaining.
