ABC News reports from South Australia about how a council in the Riverland is working to recognise the final resting places of people whose graves were unmarked because of the stigma of suicide at the time.
Dave Otto de Grancy from Berri Barmera Council said he initiated the project with the aim of raising awareness about the mental health services available to people today.
He said that between 1920 and 1950, people who took their own lives were buried outside cemetery boundaries in unmarked graves.
World-renowned archaeological scientist Dr Ian Moffat has been involved in the project to determine how many people were buried in the area.
He recognised the importance of finding and recording the graves, saying it would help destigmatise mental health issues, particularly suicide.
The council map of who it assumes is buried in each location will be matched with the archaeological findings.
Unmarked graves across Australia
Dr Moffat has worked in northern Australia, South Africa and Indonesia in caves that hold material from early human evolution.
He said his team was increasingly in demand as more people became aware of the geophysical methods available to discover remains.
