A 20-kilometre drive between outback towns has become the epicentre of a criminal investigation after mother-of-two Trisha Graf disappeared without a trace.
Timeline of the Night
Graf left the Roxby Downs Hotel at 12:19 a.m. on 12 December, travelling with a friend. After striking a kangaroo on the road to Andamooka, the pair continued to a north-western home in the opal-mining town. She departed alone for her nearby house just before 2:00 a.m.; no one has reported seeing her since.
Key moments that morning:
- 12:19 a.m. – exits hotel
- ~1:00 a.m. – roo collision near township
- 1:50 a.m. – leaves Andamooka home
- 2:00 a.m. – last seen on Dunstan Drive
- 12:00 p.m. – partner and friend find her stranded 2012 white Ford Territory, rego S254BCX, marooned on a mound east of the Blue Dam
Search Efforts
State Emergency Service crews, police air-wing, local volunteers and divers scoured surrounding scrub and waterways. Detective Superintendent Darren Fielke says the lack of footprints or clues is deeply troubling.
> “Her thongs were found with her vehicle and we would have expected to locate her if she had simply wandered off a short distance.”

Investigators are now appealing for:
- Patrons who spoke with Graf inside the Roxby Downs Hotel
- Residents or drivers who saw the damaged Ford after 1:50 a.m.
- Anyone with dash-cam or CCTV footage from Dunstan Drive
