The Kurralta Park man, whose name is suppressed, made no application for bail in a short appearance before Port Augusta Magistrates Court on Tuesday.
He was charged with both the murder of Jasmeen Kaur and with failing to notify police of a reportable death.
Kaur was reported missing on Saturday. Her body was found by detectives on Monday, buried at Moralana Creek, about 40 kilometres north of Hawker.
Major Crime Detectives interviewed the 20-year-old man on Sunday, who then took detectives to the shallow grave site.
Kaur had last been seen alive at a nursing home in Adelaide on Friday night.
Court documents allege she was killed between then and Monday at Parachilna or other places.
The charged man was remanded in custody to appear in court again on December 15.
A prosecutor told the court that the lengthy delay in the “complex matter” was necessary to allow for the collection and analysis of DNA and other evidence and for the Director of Public Prosecutions to consider the material before making a final charge determination.
The Kurralta Park man was known to Kaur, but they were not in a relationship.
