As both Andrew Glazebrook and Matthew Hall (one of "The Australian 
Distributed Dudes (http://www.arrakis.com.au/~psyke/dudes.html)" ) 
pointed out, Australia is 7682300 square km.  (I had accidentally 
used the area of South Australia).  This means:

If keys were grains of wheat, the keyspace would be large enough to
cover Australia 1.92 inches deep.
