Re reading some of this stuff makes it sound like you are doint the trip on a camel.
Its simply not that hard. Its a sealed highway all the way, except the part the washed away recently!!
People do this drive every day for goodness sake.
There is plenty of traffic, you will see other cars every 1/2 hr or so.
5 days from sydney? only if you stop at every pub. 2 1/2 days from Darwin - Sydney via ISA, just under 2 days from Darwin - Adelaide both trips only during daylight hours.
Be sensible, water food and I forgot the music, check the roads and weather and just do it.
Oh yes, forget the nonense about crocs, you will not even see a croc driving, Simply nonsense. even when you get there they won't be an issue unless you intend swimming in the local Top end rivers and creeks.
As for Wolf Creek, forget that as well, better watching the "End of the World" just as much relevance.
Having said that I did meet Murdoch or his brother driving between Burketown and Normanton whist carrying out some running repairs
