Thanks Outnabout and MT for your wise words.
I never considered landing on the lake as I don't want salt anywhere near my aircraft, as well as the depth perception/getting bogged stuff that happens with salt lakes,
Mt Ive is the go! They have a well maintained strip used regularly by the RFDS, and is not very far from the Lake.
The very nice people there are happy for me to land on the strip and drink beer until my mate picks me up on the way up from Port Augusta. The lady mentioned that there would be a large chance of getting a lift to the Lake as many of the speed type people camp at Mt Ive.
PPrune is a wonderful place!
