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.
