Hi there. Like other have said, no standard answer, it all depends on you, your vehicle and conditions.
For my money, I drive a Prado (manual, petrol) and I like to cross the dunes by approaching at around 2,000 rpm or better, and then letting the revs drop off once the magic point of the crest is reached. This seems to mean Low 2nd or 3rd for soft dunes.
I had a wonderful experience with the Prado first time, because I was advised to use High 1st. Trouble was, I also help the revs up (bloody short stroke V6, I thought) and hit the top at about 3,000 rpm (about 35 kph). Once I landed (literally) all was
well!. Since then, I realised even the Prado can be idled back to 1,000 or less as the crest is approached.
Of course, with auto trans, all is different: I have heard of people using High range auto, where the transmission shifts up when you lift off your right foot at the crest!
One of the real beauties of the Simpson is the huge range of scenery and conditions, with lots of stretches of relatively easy going, when the speed limit of 40 kph may seem silly (but we all stick to it, naturally).
The other point is that it's not easy to grab a lower gear if you're in High 1st. But if your are in, say, Low 3rd, you can change up or down pretty quickly if you have mis-read a dune.
But there really are no absolutes, beyond common sense and experience.
