Celebrating the 150th anniversary of the Overland Telegraph

2022 is the 150th anniversary of the Overland Telegraph.

The Australian Overland Telegraph Line was a 3,200 km (2,000 mi) telegraph line that connected Darwin with Port Augusta in South Australia. Completed in 1872, the Overland Telegraph Line allowed fast communication between Australia and the rest of the world. It was one of the great engineering feats of 19th-century Australia and was a significant milestone in the history of telecommunication.

Charles Todd, Superintendent of Telegraphs, was the planner, designer, and driving force behind Australia’s greatest infrastructure project, the Overland Telegraph. It was revolutionary. He successfully reimagined communication with Europe and the world.

Colonel Light Gardens with Keith Conlon

Before ANZAC Day 2020, Keith Conlon spoke to David Bevan on ABC Radio Adelaide about Colonel Light Gardens and its strong World War 1 connections.

Keith is Chair of the South Australian Heritage Council.

Listen to the interview.

Just prior to its layout in 1921, the Grange Farm, (purchased by the State Government), became a major World War 1 army training camp 1915-1920. After the war there was a shortage of housing with so many soldiers returning home, and so the government introduced the Thousand Home Scheme, the first major public housing scheme in Australia. About 700 were built in the new suburb in the 1920s.

The South Australian Heritage Council proposed it be a State Heritage Area and it was declared as such in 2000.

Sir Samuel Way Building to be restored

Often seen in TV news bulletins, the Sir Samuel Way Building in Victoria Square was in its own news story in November 2020. ABC TV News Report Alina Eacott talked to the Chair of the South Australian Heritage Council, Keith Conlon, about its origins as a grand department store in 1916 and the huge blaze which gutted the building in 1948.

One of the best known State Heritage Places, the building exterior will be restored, thanks to a decision through the November 2020 State Government Budget.
