I found my parents. Sort of.
Mum called from some semi-unintelligible place in rural Queensland and said they were planning to hit the famous Birdsville Track, once known as "the loneliest road in Australia" (that's saying something). It was opened as a cattle route in the 1860s and passes through both the Strzelecki Desert and Sturt's Stony Desert.
Sooner or later they're going to end up at Uluru (which was called Ayers Rock when I was a kid). Now that's a place I'd like to see.
