Those two statements are interesting when read together. It does suggest 
that Australia Post is moving away from postcode boundaries that spilt

Maybe there is so little hand addressed mail now that they can OCR the 
entire address and code it down to the delivery route level; all the 
postcode does is differentiate between localities with the same name.
