When you go to this address
http://www.nowwhereroute.com/alpga/LocatorPlanner/searchpage.aspx
Go to the Auto trip planner section on the right hand side and put Ceduna as your start point and norsman as your destination and it will ask if it is norsman WA and select it and it will bring up the nullabor and all the LPG sites.
No more than 200km between points.

I think all the roadhouses have caravan parking, but i expect it would be a bit noisy - don't know the price because we prefer the solitude of bush camping or just getting out into the wide open spaces. We have been across twice and thoroughly enjoyed the drive; once early last year and second time was in January this year - we used air con in the car only on the hottest days. When you get to Ceduna, other travellers we have met along the way recommend the Shelly Beach Caravan Park a bit south of Ceduna - they have especially mentioned it as one of the best they'd been to. We go to the Shell or BP (Shell fuel usually a bit cheaper but can't speak for gas), as both offer good hot showers for $3. Water quality across the Nullabor is not the best.

Enjoy your trip, take it easy, and don't travel after dark (danger of hitting wildlife).

Safe and enjoyable travels, Motherhen
