quicko: the brisbane line defense strategy

Now I haven't researched this fully (read: one of my friends once told me it was true), but evidently during World War II, Australia had an official government slogan that was "if things get really way too bad, then we're willing concede everything north of Brisbane."

Let's hope this wasn't common knowledge back then.

And, please, if this post incites you to comment overly quickly, think carefully how you phrase your response.  Relax.  Talk it out.  Then go ahead and correct me nicely.
