Each state has its own school education authority, but there are  
moves towards a national school curriculum. Whether there will be  
room for variations in content for each subject remains to be seen.

BTW there are  more bad things, including some wrong stuff, as well  
as some good things in the NSW physics syllabus.  The NSW Board of  
Studies makes a point of consulting many groups of interested  
parties, but often ignores the advice it gets from the subject matter  
experts (sometimes with good reason).
