Suspected human remains have been discovered near Andamooka, the remote South Australian outback town where mother Trisha Graf went missing, prompting police to launch a formal investigation. The find is a significant development in a case that has left Ms Graf's disappearance unresolved, and authorities will now need to confirm the identity of the remains before determining how the case proceeds.

Police have not yet confirmed whether the remains belong to Ms Graf, and forensic examination is expected to be required before any formal identification can be made. Further details about the location and circumstances of the discovery, as well as the background to Ms Graf's disappearance, have not been made available in the reporting.
