What's with blob of parallel watersheds in the middle of Australia?

I checked on google maps, it's the Simpson Desert, it kinda looks like that. Anyone know why?

Wikipedia says:

The Simpson Desert is an erg that contains the world's longest parallel sand dunes.

parallel dunes

I'm guessing this part of the map uses the actual surface topography, ie how precipitation would run off through the troughs of the dunes, rather than the underlying aquifer structure. Hmmm 🧐.

Why do they all run straight for hundreds of miles? None of the other deserts are like that.

It’s just more efficient to manage. We got to do a lot with very little.
