A group of about 20 people will this morning set off to walk the Kokoda Track in Papua New Guinea.
They're retracing the steps of 246 people from the Salvation Army, who provided behind-the-scenes help to Australian troops along the Kokoda Track during World War II.
The group, from across Australia, will also unveil a memorial to be placed on the beginning of the track.
Salvation Army Captain Jacob Robinson, a youth co-ordinator for central and north Queensland, says the Salvation Army was vital to the Kokoda and other PNG campaigns.
"They would make up the tea and speak with the soldiers and just lend a listening ear to lift the morale of the soldiers, or the platoon or whoever they were ministering to. Giving refreshments and entertainment and chewing gum, and pretty much doing whatever they could to lift the spirit of the soldiers."
Jacob Robinson says he expects the walk to take about 9 days.
