2022 $1 150th Anniversary of Australian Overland Telegraph Line Coin & Stamp Cover PNC - RAMLife in Australia changed forever when Charles Heavitree Todd's Overland Telegraph Line opened. An extraordinary engineering feat, the line stretched 2,839km from Port Augusta to Darwin through unknown and hostile territory, on 36,000 poles.This 2022 $1 uncirculated Coin commemorates the 1872 opening of the line and Australia's historic telegraphic connection with the rest of the world.In 1872, the South Australian Government completed the Overland Telegraph Line from Port Augusta to Port Darwin, and from there connected to an undersea cable that led to Europe.Postmaster-General Charles Heavirtree Todd had promised it would be done in 18 months, despite arid central Australia being mostly unexplored. He mobilized three large workforces, led by engineers, surveyors, and explorers, to install 2,2839km of galvanized number 8 fencing wire on 36,000 poles.The line was joined, seven months late, at Frew's Ironstone Ponds, N.T.  Then, at 1.10pm pm August 22, Senior Telegraph Officer J.A.G Little tapped Morse code into his handset, in Port Darwin. Fifty minutes later his message was read in Adelaide.Soon after, electric communication through to London within 7 hours was a daily occurrence. The 'tyranny of distance' was conquered, and life in Australia was never the same again.The coin's reverse describes the 150th Anniversary of the Overland Telegraph Line.The coin's obverse features the Jody Clark effigy of Her Majesty Queen Elizabeth II and the monetary denomination.Affixed to the envelope is an official Australia Post International $1.10 stamp.
