'Ghosts' of lost soldiers walk in Adelaide

People wearing past and present Australian military uniforms will march through Adelaide on Wednesday to remember soldiers lost in conflicts.

People in Adelaide will come face-to-face with the 'ghosts' of Australian soldiers who died fighting in wars across the world.

A group wearing Australian military uniforms from past and current conflicts will parade through the city on Wednesday to encourage reflection ahead of Remembrance Day on Friday.

Each will hold a card with the name and service details of an Australian who died at war.

The soldiers will be portrayed by RSL volunteers and members of Re-enact SA, while the Barossa Light Horse Historical Association will also be promoting the RSL's Poppy Appeal.

"This will truly bring home the sacrifice and the loss suffered through war - and how we must never forget," RSL SA chief executive Julia Langrehr said.

The initiative has been inspired by a similar event in the UK last year, in which people in WWI uniforms stood at train stations and shopping centres to mark the centenary of the Battle of the Somme.
