A body believed to be that of missing French tourist Aurelie Lhorme has been found at the base of a cliff on South Australia’s far west coast, police say.

Ms Lhorme, 30, was last seen in her parked car near the Head of the Bight Whale Watching Centre, near the Nullarbor Plain, on Saturday night.

“Police can confirm that the body of a woman has been found at the base of a cliff near Head of Bight,” police said in a statement on Monday evening.

“The body is yet to be formally identified.”

Police Special Tasks and Rescue officers abseiled down the cliff on Monday and confirmed the body of a woman had been found.

Staff at the centre had spoken to her after she appeared to be sleeping in her car on an access road.

Her car was found in the same spot the following morning, along with her mobile phone, wallet and passport.

A search on Sunday, involving an Aboriginal tracker, failed to find the woman and resumed on Monday.

Police want to speak to the occupants of a Jayco motorhome, which was parked next to the whale watching centre on Saturday night, who may have had contact with Ms Lhorme.
