History & Assignment of Australian Postcodes
Why have postcodes?
Postcodes are allocated to geographic areas to facilitate the efficient processing and delivery of mail to customers. The current four digit numeric postcode system was introduced in 1967 in association with the first mechanised mail processing centre in Australia.
Who is responsible for naming localities and defining boundaries?
The government land administration agencies in each state are responsible for gazetting locality names and boundary positions.
Postcodes are only allocated to localities officially gazetted by State land agencies. In the majority of circumstances, a postcode covers an area comprising of more than one locality. Unofficial or non–gazetted localities are not recorded in the Australia Post postcode database.
While land agencies are responsible for the gazettal of localities, the local council or shire recommends localities and their proposed boundaries for gazettal.
How is it determined if a new or existing postcode is to be allocated?
The decision as to whether a new postcode or an existing postcode is to be allocated to a locality is based on operational efficiency. Issues that underpin the decision are critically analysed; these include the configuration of the Australia Post network, transportation connections and delivery arrangements.
Why change an existing postcode?
Because the adoption of new or changed postcodes by customers is slow, changes are only made where significant reasons for change are established.
A postcode change will only be considered if such a change leads to either enhanced postal service or operational efficiency to the Australia Post organisation.
