Shortcut from Walkers Crossing to Coongie Lakes ?

In a nutshell, it’s a closed road to the public and you will not get permission to use it.

We used to travel those tracks before it all became NP, also before Walkers crossing became the established PAR as we would meet up with the western end of the current Walkers Crossing track. You couldn't get across the creek near Kudemetchie (sp) if there was too much water in it. You could also keep going NW and miss the tail of the Coopers and come out further north on the Birdsville Track. They were all either rabbiters tracks or station tracks.
Used to visit Lake Massacre and the memorial plaque to Charlie Grey as well.
I will always remember the first time we went across that way and we hit a much bigger track that had more traffic and we stopped to work out where we were. While we were consulting the topo map and measuring the k's we had travelled since the last known location (no GPS in those days) an old bloke came along in a beat up F100 and stopped to chat as everyone did in those days. After remarking on the weather and state of the country he eventually asked "where did you fella's come from today?" our reply of"that faint track there" met with astonishment and even more astonishment when we asked "is this the Birdsville track?" as his laconic reply of "well you've been driving on it since Maree" . He had no idea that track went anywhere and had lived there all his life!

That looks like my old map when I passed through. The issue is that it's private active mining land. I had special permission which wasn't difficult to get at the time, but as Steve said, there is no guarantee, and I am sure it's tougher now than then.

The tracks appear to move or get unused, as I noted in that post. I would not be surprised to see that those are no longer traversable these days.
