Cwamit,
Thank you for the input.
I met someone from the country today. it seems that there is no consistent wind inland, only cold fronts, if they are strong enough to reach that part of the OZland, which does not seem to be the case at the moment.
It has not rained for a fair while over there, so salt lakes can still be expected to be hard flat white surface

...perfect for mountainboarding

Any additional input from persons from inland?
Cheers,
Fred
