It's a step in the right direction because, there is much better address format and suburb validation than the click and send download, but a major annoyance is they only print 1 label per page rather than 4 in click and send.  Does anybody know of a work around?

I am going to go out on a limb here and posit that the Suburb validation requirement through C&S is a GOOD thing. The item is far more likely to arrive at the destination when it's addressed in accordance with AP's requirements.
