The most egregious myth about Federation is that it was all about domestic issues, particularly economic issues, and that defence and foreign policy played little or no part in the impetus towards Federation. The argument runs that because little time was spent debating issues of defence and foreign affairs in the constitutional conventions, and much more time was spent on economic and fiscal matters, the latter must have been the most important drivers of Federation. The argument is unjustified in the face of the evidence. Defence and external affairs are the key to understanding the push for Federation.
