The 12,000 mile perimeter of Australiais too long for all-around defense by the limited
forces available. The terrain offers few serious obstacless. Communications are poor by American
standards and virtually nonexistent outside of  the vital areas. A significant   war Industry has
been developed, but it is rendered vulnerable by dependence on outside sources for essential
materials.
 
               (b) New Zealand, with a population of 1,600,000 in 100,000 square miles, is divided

is disproportionate to the area and the vital points  are the coastal cities of Aukalnd, Wellington,    
Christchurch, and Dunedin.
