Detailed analysis is then required of duplicate named Localities within

neighboured to other Localities with the same Postcode. The next
production stage involves the examination and allocation of Postcodes to
gazetted Localities that either have no delivery service or have not yet
been assigned a Postcode within the Australia Post database. This
requires liaison with state-based Postcode controllers and in turn
state-based delivery operations. This is an ongoing process and as a
result, Postcode Boundaries will always be subject to change according
to the needs of delivery operations. Locality boundaries are
subsequently Dissolved/Aggregated based on the Postcode attribute. "/

They do also say this: /"Postcode Boundaries is produced through a
partnership with Australia Post and *provides the official
representation of postal delivery areas across Australia*."/
Those two statements are interesting when read together. It does suggest
that Australia Post is moving away from postcode boundaries that spilt
gazetted localities.
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.
