We talk about 'Telegraph Todd' and the construction of the Overland Telegraph Line, built through the largely unsurveyed and vast centre of Australia.  Only one group of British explorers had, to date, survived a trek all the way from the south to the north and returned, but using the information they recorded, Todd was sure he could supervise the construction of a more than 3200km Telegraph Line, that would allow the colonies in Australia to be linked up the the rest of the world.  A huge leap into a more modern communications era.
