Police have today returned to Andamooka to continue investigations into the disappearance of Trisha Graf, 41.
Major Crime Investigation Branch, STAR Group, Mounted Operations and SES members will be searching east of Blue Dam towards Lake Torrens.
The search will include approximately 1000 mine shafts and re-searching Blue Dam. The dam will be drained after a previous search by police divers was unable to eliminate the presence of evidence of Trisha's disappearance.
An update on the searches will be provided as they progress.
Trisha was at the Roxby Downs hotel at 12.19am on Friday 12 December 2025. 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 was unable to be driven because of its location on the dirt mound.
An initial ground and aerial search of the area, including Blue Dam, was conducted by police and SES followed by a further search by members of the Andamooka community. These searches have failed to locate Trisha.
Since that time police from the Far North, Port Augusta, Missing Persons Investigation Section and PolAir have conducted additional ground and aerial searches without success.
Anyone with information about Trisha's whereabouts or her movements leading up to her disappearance is urged to contact Crime Stoppers online at www.crimestopperssa.com.au or on on 1800 333 000 - you can remain anonymous.
