It was the largest and most difficult infrastructure project of the 1800s, involving the first international telecommunication system. It spanned uncharted territories, including deserts and jungles, and connected continents via submarine cables.
They had to navigate unexplored territories, uncertain weather conditions, and harsh environments. They faced potential penalties for delays and had to compete with other states like Queensland and New South Wales for the project.
It revolutionized communication, allowing farmers and mining companies to access real-time market prices. It transformed politics and business by connecting Australia to the global economy, much like the internet does today.
Alice Springs was a crucial outpost on the telegraph line, serving as a relay station. Its existence was directly tied to the telegraph, and it became a key settlement in the outback.
The line disrupted traditional lands and ways of life. Aboriginal people sometimes sabotaged the line for materials, but the telegraph companies later adopted strategies to reduce conflicts by leaving spare materials for them.
Porthcurno was a global telecommunications hub in the 19th century, with 14 cables connecting the British Empire. It was the landing point for submarine cables linking the UK to its colonies, including Australia.
The term was coined by Claude Chappe, who invented a mechanical telegraph system using towers and movable arms. It originally referred to a system of visual signaling over long distances.
Morse's system used a single wire and required operators to learn Morse code, making it cheaper and simpler to implement compared to systems with multiple wires like the British Cooke and Wheatstone telegraph.
Gutta-percha, a latex-like substance from Malaya, provided the necessary insulation for the copper core of the submarine cables, protecting it from the ocean environment and marine life.
Early cables often failed due to insufficient insulation, floating on the ocean surface, or being damaged by marine life like sharks and worms. Laying the cables was also technically challenging, requiring precise navigation and coordination between ships.
