The story of Australia's first overland telegraph wire is told in the documentary Constructing Australia: A Wire Through The Heart (2007).
It is the tale of two remarkable men – Charles Todd, a scientific genius, and John Stuart, a fearless and dedicated explorer.
In the mid-1800s Australia was still a very isolated land. Stuart, a migrant from Scotland, was determined to cross the centre of Australia and reach the north coast. Meanwhile, Todd was dreaming of constructing a telegraph line through the heart of the continent. Together they paved the way for a communications revolution.
