The Australian Postal Corporation, operating as Australia Post, is the government-owned corporation that provides postal services in Australia. The head office of Australia Post is located at 111 Bourke Street, Melbourne, which also serves as a post office.
Australia Post is the successor of the Postmaster-General's Department (PMG), which was established at Federation in 1901 as the successor to the colonial post services. In 1975, the PMG was abolished and its postal functions were taken over by the Australian Postal Commission. The organisation's current name and structure were adopted in 1989 as part of a process of corporatisation.
