Changing Australia: Andrea Gerrard and Ian Hopley and the search for unmarked veteran graves

Around Australia - even around the world - you can find gravestones marking the resting places of Australian veterans who lost their lives in war.But for those who made it home, many died with little recognition of their service - families perhaps unable to afford a proper headstone.It's inspired a movement to find the unmarked graves of World War I diggers tracking down surviving family members and providing headstones that recognise their service.
