Someone might not want to nuke Sydney, but if someone nukes Japan-or anyone else in Asia-Australia is definately going to feel it.
Since when?Last i checked we were an island continent,sharing no borders,and California is closer to NK than Australia is.If you mean due to proximity,then Hawaii is part of Asia too:P.And btw,i dont think it's safe to say no one would like to see Sydney nuked,Australia isnt so far behind the US when it comes to hostility from most of the world.
