Our founding document's preamble doesn't even mention Western Australia, because the state was so reluctant to federate in the first place. By the time the Sandgropers did hop aboard, it was too late for the document to be re-drafted. And they've been itching to get out ever since. 

The motion put forward by the Brand division of the Western Australian Liberal Party to examine the possibility of WA pursuing secession is just the latest example of those perpetual malcontents trying to unhinge themselves from the rest of the continent and drift off towards South Africa.
