Hi Al, sounds like a great plan. I was out that way in October spending time at Wilpena, Arkaroola and Broken Hill. If you get the chance should try a charter flight over the Ranges. Ridgetop tour at Arkaroola is definitely worth it and they also have a couple of observatories on site there so if you try and plan around New Moon would be well worth it. Balcanoona is a historic site worth checking out in the Gammon Ranges NP.
Had a couple of blowouts on the road to Arkaroola due to not slowing down adequately at the floodways but I had a puncture kit and compressor so thankfully got out of trouble
