Police have returned to Andamooka to continue investigations into the disappearance of Trisha Graf, 41.
Major Crime Investigation Branch, STAR Group and Far North officers will search an area on the western fringe of Andamooka for evidence over the next few days.
An update on the search will be provided as it progresses.
Police have previously conducted searches at a residential address and an area on the eastern outskirts of Andamooka as part of the ongoing investigation, but no evidence was located.
Trisha Graf 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. 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.
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.
