An Italian tourist has pleaded guilty to causing the deaths of an elderly couple and their daughter in a crash in South Australia’s Mid North last year.

Gabriele Cairo, 28, appeared in the Adelaide Magistrates Court on Tuesday and pleaded guilty, via an interpreter, to causing the deaths of 84-year-old Clare woman Cynthia Clark, her 86-year-old husband John Clark and the couple’s 54-year-old daughter from Jamestown, Jacquie Clark.

The two women died at the scene of the crash, at the intersection of Templeton and Blyth Roads at Everard Central, near Blyth, on October 31.

Mr Clark was flown to the Royal Adelaide Hospital with serious injuries and died a week later.

Cairo, who was driving a hire campervan at the time, also pleaded guilty to causing serious harm to his wife Elena Perrone.

Ms Perrone sustained serious injuries in the crash and was flown to hospital from the scene, about 120 kilometres north of Adelaide.

Another charge of aggravated driving without due care was withdrawn.

The court has previously heard Cairo was in Australia on a tourist visa.

His lawyer, Michael Woods, asked the court if the matter could proceed to sentencing as soon as possible.

Outside court, Mr Woods said his client was feeling “devastated” and wanted the matter finalised quickly “for the sake of everyone”.

He said Cairo’s time in Australia was “up to the court”.

He will next appear in the District Court to begin the sentencing process in July.
