A new memorial dedicated to all conflicts - past and future - will be unveiled by the Governor this weekend in Crystal Brook.
The opening will take place in Adelaide Square on Sunday and marks the centenary of the town's RSL sub-branch.
The memorial acknowledges the service of all men and women in all theatres of war and conflict from the local area.
Cheryl Cates, state president of RSL SA/NT will also be presenting the sub-branch with a certificate noting the 100-year mileston.
The centenary of the awarding of the Victoria Cross to local man, Corporal Arthur Percy Sullivan, will also be commemorated on the day.
Corporal Sullivan received the VC for his bravery in the North Russia Relief Force in August 1919.
Without hesitation, under intense fire, Corporal Sullivan rescued an officer and three men who had fallen into a river after attempting to cross the stream on a plank while under fire from Bolsheviks.
He rescued the men one by one and was subsequently awarded for his heroic actions.
His life was unfortunately cut short when he slipped and hit his head on a roadside in London on April 9, 1937.
Corporal Sullivan had been in London attending the coronation of King George VI.
His Excellency the Honourable Hieu Van Le AC, Governor of South Australia, will officially launch the memorial wall with festivities due to start from 11.30am on the Sunday.
Following the formalities, master-of-ceremonies Ivan Venning will encourage guests to visit the Crystal Brook Heritage Centre to learn about the heroic war-time exploits of Corporal Sullivan, or Sully as he was most commonly known.
A book written by the sub-branch's Christeen Schoepf, looking at Sullivan's life in Crystal Brook, will be launched on the day.
