Aboriginal people around the country practise their own complex spiritual practices around burial.
Complex burial practices in South Australia will become some of the most well-documented.
At Roonka Flat, near what will become known as Blanchetown, people have been buried in strategically placed graves in a large burial ground or cemetery.
In some instances, people are buried in soft sand on the banks of the Murray River, or their bodies are placed in the hollow trunks of trees.
At Roonka, the Ngaiwang people also bury the dead with elaborate and unique ornaments.
It is here that a young female estimated to be between 16 and 19 years old is buried with a headband, made of wallaby or kangaroo teeth, which is embedded into her skull.
It could mean she was a significant figure in the tribe, perhaps considered as a queen or princess.
Ngaiwang people are also buried here in possum skin cloaks held together by bone pins.
Some are buried sitting up in their graves or lying on their side.
Others are buried with animals which may have been their totems.
