A witness in the small town of Ninyeunook in Victoria’s rural northwest said they saw Ms South on Sunday, July 3, between 3pm and 3.30pm. Ninyeunook is about three-and-a-half hours from the SA border.

7NEWS reported Ms South was due to move into a house in Queenstown, near Port Adelaide, on July 1 but never arrived.

Her family said her bank accounts have not been touched.

“There’s just no lead to find her … all I can keep thinking is where is she? I need to help her,” said Veronica South, Ms South’s daughter.

“There’s no sign of her, but we’re just going to keep looking, but where do we go, there’s just no lead to follow.”

On the back page of Ms South’s notebook, found by her family in Adelaide, was a troubling message reading, “help me please”, 7NEWS reported.
