Two people have died in a fiery outback crash in South Australia, while a man has been killed in a rollover on a private property in the Riverland.

Key points:

  • Two people have died in a crash on the Stuart Highway
  • Another man died in a ute rollover near Morgan
  • A motorcyclist has sustained life-threatening injuries in a crash near Mount Gambier

Five other people have also been badly injured in crashes over the Adelaide Cup long weekend.

The driver of a ute — a 23-year-old man from the ACT — and the passenger of a B-double truck — a 57-year-old woman from the Adelaide suburbs of Para Vista — died when their vehicles collided about midday yesterday on the Stuart Highway at Wirraminna, in the state’s far north, between Pimba and Glendambo.

Both vehicles caught fire on impact.

The truck driver — a 49-year-old man from Para Vista — is in a critical condition in hospital.

Police say the highway will stay closed to all traffic for several days with diversions in place as the road surface has been significantly damaged.

Ute rollover near Morgan

The man who died in the Riverland crash was a 26-year-old from Campbelltown, in Adelaide’s east.

Emergency services were called to a private property off Wonga Road, at Lindley — near Morgan — after reports of a single ute rollover about 6:00pm yesterday.

Police did CPR until paramedics arrived but the man could not be saved.

The driver of the ute, a 29-year-old Athelstone man, and two other passengers, a 34-year-old Tanunda man and a 29-year-old Klemzig man, were all flown to Adelaide with non-life threatening injuries.

Motorcycle crash in south-east

In the state’s south-east, a 63-year-old male motorcyclist has suffered life-threatening injuries after a crash at Kongorong, near Mount Gambier.

The man came off his bike on an unnamed access road off Bannisters Road about 5:50pm yesterday.

A total of 21 lives have been lost on South Australia’s roads this year, compared with 17 at the same time last year.
