Army Signallers gathered at Melbourne's Shrine of Remembrance to mark the 100th anniversary of the Royal Australian Corps of Signals (RA Sigs).
The corps initially formed on February 14, 1925, consolidating technical specialist soldiers trained to operate analogue wireless and radio equipment.
Today, the corps provides contemporary digital communications, electronic warfare and cyber capabilities in support of Defence's operations around the world.
Head of the corps, Brigadier Deane Limmer, said the parade and commemorative service recognised the contribution and sacrifice of signallers in theatres of conflict, peacekeeping, and humanitarian assistance and disaster relief.
"A key element in any battlespace or operating environment is the timeliness and reliability of our communications, and the information that guides decision-making to give us a competitive edge," Brigadier Limmer said.
"We have always embraced technology and the skills required to meet the dynamic demands of warfare, as per our corps motto: certa cito - swift and sure."
Events to celebrate the achievements and the centenary of RA Sigs will take place throughout 2025.
"More than 100,000 signallers have served in the corps, including 25,000 men and 3600 women who served as communicators in either the Australian Corps of Signals or the Australian Women's Army Service during the Second World War," Brigadier Limmer said.
"For every signaller serving in the corps there is someone providing strength and support at home, and our centenary celebrations are also about recognising and showing gratitude to them."
