Police searching for missing South Australian woman Trisha Graf have combed through a septic tank close to her last known whereabouts as they ramp up their desperate search in the outback.
Ms Graf was last seen in the early hours of December 12, 2025 in the remote SA mining town of Andamooka around 2am.
Her car was found by friends hunting for her some 10 hours later, but she was nowhere to be found.
Last week, police investigating her disappearance resumed searches in the area.
On February 23, officers combed through a septic tank at a property near her last known whereabouts – but recovered no evidence.
Treacherous weather conditions then curtailed the search efforts until after the weekend, with investigators now continuing the hunt.
This week, they will be turning their attentions to searching mine shafts close to home east of Andamooka.
On the night of her disappearance, Ms Graf visited the Roxy Downs hotel, leaving a short while after 12.19am in her white 2012 Ford Territory, bearing the registration S254BCX.
She is known to have struck a kangaroo in her car a short while later, close to the Andamooka Township.
Ms Graf continued her journey and visited a friend in the town, before last being seen driving along Dunstan Drive at about 2am.
Her car was found perched on a dirt mount near the Blue Dam, east of Andamooka.
Anybody with information about her disappearance is encouraged to contact Crime Stoppers on 1800 333 000.
