A 41-year-old mother of six, Trisha Graf, vanished mysteriously from the remote opal-mining town of Andamooka in South Australia on December 12. The tiny community, located 600km north of Adelaide with a population of just 250, has been at the center of an intensified police search.
The Desperate Final Phone Call
Hours before disappearing, Ms. Graf made an urgent call to her partner, Tony Gregory, from a pub in Roxby Downs, 30km away. Her 12-year-old son, Max, detailed the conversation during a live appearance on a true crime podcast, with his father’s permission.
Max explained that his mother called in a panic because her card was declined at the pub, just before closing time. “Dad had earlier forgotten to transfer money to the card that mum had, and it was declined,” Max said. “Mum called Dad and was like, ‘There’s no money on the card, hurry up, quick, before (the pub) closes.'”
Mr. Gregory transferred the funds, but it arrived too late. CCTV footage captured Ms. Graf at the Roxby Downs Tavern around 12:19am. A man reportedly paid for her beer. She then left in a white 2012 Ford Territory with her acquaintance, Kymberley Conniff, also from Andamooka.
The Journey Home and Vehicle Discovery
En route to Andamooka, Ms. Graf struck a kangaroo outside the town. Despite the damage, she and Ms. Conniff proceeded to a house in the north-western area. Shortly before 2am, Ms. Graf departed alone for a quick five-minute drive home along Dunstan Drive.
Mr. Gregory awoke to find her gone and checked her friend’s place. Around midday on December 12, he and a friend located her damaged Ford Territory perched on a dirt mound near Blue Dam, east of town—a spot Ms. Graf had never visited. A pack of VB beer remained in the back seat, missing one bottle.
Max, who slept at a friend’s house that night, sent his mother a final text: “Goodnight Mum, I love you.” The next morning, his friend’s mother told him, “Dad wants you home.”
Police Raids and Ongoing Searches
South Australia Police recently raided the last known residence where Ms. Graf was seen alive and resumed searches of nearby mineshafts. The case is now classified as a major crime investigation.
SAPOL Major Crime detective superintendent Darren Fielke described Ms. Graf as “a very good mother for all intents and purposes.” He noted her home was “clean” and “in pristine condition,” adding, “It is out of character for her not to be in contact with her children, her partner, or to have untouched bank accounts.”
Family Concerns and New Leads
Mr. Gregory, who joined Max on the podcast, aims to raise awareness. “She’s done runners before, but she’s always kept in contact,” he said.
Ms. Graf’s mother, Anne, from the Barossa Valley, insisted, “Trisha would never leave her children in a million years.” She fears foul play, stating, “You’d have to have someone else involved,” and suspects a mine shaft concealment.
Weeks prior, Ms. Graf listed valuable uncut opals—a $2,000 ‘Squid Fossil opal’ and a $700 ‘Cockle shell opal’—on a Facebook trading group. Her daughter Montanah called this “strange,” unaware of the stones. Police are pursuing all leads.
Max questioned the timeline, noting his mother knew Ms. Conniff casually for drinks only. Family home CCTV from the time had overwritten.
Description and Appeal for Information
Ms. Graf was last seen wearing black pants and a black top, hair in a plait, with nose, lip, and ear piercings, plus tattoos: a skull on her upper right arm and a mermaid on her lower forearm.
Anyone with information on her whereabouts or movements is urged to contact Crime Stoppers on 1800 333 000.
