On Tuesday 13 January 2026 Major Crime Investigation Branch detectives will resume search activities in Andamooka in connection with missing woman Trisha Graf, 41.
The search activities will take place at several locations identified during recent investigations into her suspicious disappearance.
Major Crime Investigation Branch officer-in-charge Detective Superintendent Darren Fielke said the searches would focus on locating evidence related to the investigation.
On Wednesday 14 January 2026 detectives will conduct doorknocks in Andamooka in the vicinity of several locations Trisha Graf was last seen.
"We have established Trisha's movement's on the evening and morning she was last seen, but we believe there are people who may have seen her within the town who have not yet contacted police,'' Det. Supt. Fielke said.
"We know there were people who were with Trisha at both the Roxby Downs Hotel and who saw her after she returned to Andamooka and we need to speak with them.''
Trisha Graf was at the Roxby Downs hotel at 12.19am on Friday 12 December. She left a short time later and was driving a white 2012 Ford Territory, SA registration S254BCX, accompanied by a friend.
After leaving the hotel Trisha travelled from Roxby Downs towards Andamooka before colliding with a kangaroo a short distance from the Andamooka Township.
After striking the kangaroo Trisha and her friend continued onto Andamooka where they visited a home in the north-western area of the town. After a short time Trisha left just before 2am to travel the short distance home. Trisha was last seen driving along Dunstan Drive, Andamooka.
Just after midday on Friday 12 December 2025, Trisha's partner and a friend were searching for her when they located Trisha's Ford Territory, which was perched on a dirt mound near the Blue Dam east of Andamooka.
The vehicle had accident damage caused by the collision with the kangaroo, but was unable to be driven because of its location on the dirt mound.
An initial ground and aerial search of the area was conducted by police and SES followed by a further search by members of the Andamooka community. A search of the Blue Dam was subsequently conducted by police divers. These searches have failed to locate Trisha.
Since that time police from the Far North, Port Augusta, the Missing Persons Section and Polair have conducted additional ground and aerial searches.
On 6 January 2026 police declared the suspicious disappearance of Trisha Graf a major crime.
Anyone with information about Trisha's whereabouts or her movements leading up to her disappearance is urged to contact Crime Stoppers on 1800 333 000 or online at www.crimestopperssa.com.au - you can remain anonymous.
