Post & Telegraph/Post Office Tasmania
The ‘Post & Telegraph Department’ was reported in Tasmanian newspapers from 1892. However, telegraph was established in Van Diemen’s Land as early as 1821, with “Post & Telegraph” offices built around Australia in the 1860s.
Following Federation the colonial post and telegraph services came under the control of the Post Master General’s Department. It was not until 1975 that postal services were separated from telegraphic communications when the PGM was split into Australia Post and Telecom.
