Birdsville to Broken Hill

Or Cordillo Downs?

Or via Haddon Corner / Arrabury Rd, with a side trip to Betoota and Deons Lookout ?
Only a little longer, but interesting especially Betoota.

Walkers / Cordillo are pretty much quickest, much of a muchness distance / time wise.

I have been to Birdsville 4 or 5 times & Walker's Crossing has been closed every time, maybe next time?

A great option Shaker, bad luck it was closed, as if other roads are open in the area it is usually ok. Must have been some good rain.
You have to watch the mining roads going south from north of Moomba and around Fly Lake, unless you have a good mapping system BV to Inna and getting onto the Fifteen Mile Tk can be a bit iffy, but I think signage is improved now.

There are tracks everywhere between Moomba and Walkers Crossing. They are mostly Santos roads with a PAR so we can travel through. Signage is not always good. I believe Santos move the PAR from time to time to suit their mining operations. In 2014 I travelled from Innaminka to Walkers Crossing. The sign just before Moomba to turn north was not there and I continued on and turned north just after Moomba. This road passes the Gidgialpa Gas Field (very interesting), I eventually realised I was on a Santos mining road closed to the public. I was talking on the phone at the time, and it was also late in the day, which most likely caused my error. A great road and 80 kph no problem. By the time I woke up to where I was I had already passed several Santos vehicles without incident and at 80 kph it was not going take long to get to the end, so I continued. Got tired before I reached the end so pulled over, setup camp, and sat with beer in hand watching the mining trucks going to and fro. Never once challenged but would not advise anyone try it. My point is that if you should be confused by the signage and find yourself on the wrong road, its not the end of the world.

Yes Cookie, I have travelled this route a couple of times, signage is pretty good, plus you get to see two more of the state border corners.

Macca.
