The OP mentions a programme showing the history of Maralinga, it has been followed up by a part fictional story of the atomic testing called "Operation Buffalo" the 1st episode of which can be seen here Operation Buffalo : ABC iview if you missed it as Starts Sunday 31 May 8:30pm on ABC + iview. It has lots of Series Landies, not sure if they are period correct, as I think I saw different wheelbases, hard and soft tops, and different radiator intakes, but I'm no expert.
