Does anyone have any advice on how practical, treacherous or difficult it would be to visit dalhousie springs and Mt Dare in mid-December?

I would be coming from the south on the A87 and then via Oodnadatta. I don’t want to go into the desert more than just as far as Dalhousie/Mt dare and then returning on the same route.

I’ve never been to this area and I’m concerned about it being the wet season at that time.

Thanks for any advice
