The '''Overland Telegraph Line'''  refers to the line from what is now [[Darwin, Australia|Darwin]] on the northern coast of [[Australia]] to the southern coast at Port Augusta in [[South Australia]] effectively linking  Australia with the rest of the world.

The first successful public message using [[Samuel Morse|Samuel Morse’s]] newly perfected telegraph system was sent on 1st May 1844. By 1856 most major cities in North America  and Europe were linked. The [[Atlantic]] was crossed in 1858.

In Australia, the first telegraph line linked the business district of [[Melbourne]] with its port at Williamstown in 1854. Four years later Sydney and [[Adelaide]] had lines enabling fast communication of inbound shipping. [[Perth, Australia|Perth]] and [[Hobart]] followed. By 1869 all capitals except Perth were linked to each other. Even [[Bass Strait]] had been crossed. In that year a message could be sent from Cardwell in Far North [[Queensland]] to Port Augusta, north of Adelaide or to [[Hobart]] Tasmania in minutes.

Meanwhile telegraph lines were snaking ever further across [[Asia]] and down into what is now [[Indonesia]]. The technology required to lay undersea cable had been almost perfected. The problem with linking Australia – importantly the major centres of population – lay in the 3000 or so Km (about 1875 miles) of largely unknown arid and semi-arid land between the southern cities and the northern coast that had been traversed only once – in the early 1860s by a party led by John McDouall Stuart.

Up to this point communications with England had been solely by ship and took approximately 3 months. The completion of  telegraph communications between the mother country and its major Australasian colonies was considered to be of utmost importance. (An undersea cable would be laid between Sydney and [[New Zealand]] in 1876.)

At first it was planned that a cable from [[Indonesia|Java]] would be brought ashore at the newly founded Queenslad goldfield town of Normanton, at the south-east “corner” of the Gulf of Carpentaria and, from there,  go overland to the existing connection at Cardwell. In January 1870 the “British-Australia Telegraph Company wrote to Charles Todd, the South Australian Superintendent of Telegraphs requesting permission for cables to installed on South Australian land in what is now the [[Northern Territory]] linked to the Queensland system. Todd  managed to talk the company into bringing the cable ashore at Port Darwin and pledged Government money to span the continent southward by January 1872.

Where each repeater station was situated, a small settlement sprang up, many of which still exist, if only as a roadside pub and petrol station. These days, the largest and most well known of these is [[Alice Springs]], about half way along the line, and named after Todd’s wife.

Darwin (Palmerston) received the cable from Java in October, 1871 and started “talking” to the outside world. Todd was late. Weather, unknown mountain ranges and especially  the “Top End” wet season all hampered them. The join was finally made at an isolated spot with the optimistic name of Frews Pond, 640 km (about 400 miles) south of Darwin, 8 months behind schedule. (Fortunately, the undersea cable had broken and was out of action for half that time.)

It had taken 23 months. It had cost 479,174 pounds, 18 shillings and threepence, over double the estimate. At about 20 to the mile, it had used over 36,000 poles. Some idea can be gained of the scale of the undertaking by noting that a sealed road between Adelaide and Darwin was only completed in the early 1980s and a rail line in 1993.
