In short:

South Australian high school students have helped to uncover the legacies of five war veterans who were laid to rest in unmarked graves. 

The descendent of one veteran says he is emotional to see the digger finally receive a formal recognition.

The Headstone Project SA says more than 2,500 World War I soldiers lie in unmarked graves across the state.
