You'll be fine, the Simpson is a pretty popular place nowadays so if anything happens you'll only be a few hours off someone else coming through in popular times.
The only advice I can give is don't rush through it as it goes quickly, enjoy the time there, ensure an extra 20 litres of fuel on top of what you estimate and call out on uhf on each dune as your biggest risk would be hitting another oncoming on the top of a dune.
