Following [[Federation of Australia|federation]] in 1901, the colonial mail systems were merged into the [[Postmaster-General's Department]] (PMG). This body was responsible for [[telegraphy|telegraph]] and domestic telephone operations as well as postal mail. An airmail service was introduced in 1914.<ref name="auspost" /> In 1967, 4-digit [[postcodes in Australia]] were introduced, in addition to the world's first mechanical processing centre, which garnered international attention.<ref>{{cite web |author=Daniel Vidoni |url=http://www.storefinder.com.au/postcode-assignment.php |title=History and Assignment of Postcodes |publisher=Store Finder |access-date=24 January 2016 |archive-url=https://web.archive.org/web/20070929130828/http://www.storefinder.com.au/postcode-assignment.php |archive-date=29 September 2007 |url-status=dead |df=dmy-all }}</ref>

On 1 July 1975, separate government commissions were created to undertake the operational responsibilities of the PMG. One of these was the Australian Postal Commission. It later became the Australian Postal Corporation on 1 January 1989 when it was corporatised into what is now known as the Australian Postal Corporation, or Australia Post.
