Major Crash investigators are at the scene of a fatal crash at Tumby Bay.
Emergency services were called to a single vehicle rollover on Bratten Road, Tumby Bay, near the silos, about 4.40am on Saturday, May 18.
The driver of the Holden sedan, an 18-year-old man, sustained serious injuries in the crash and will be airlifted to hospital in Adelaide later today.
His injuries are not life-threatening.
Sadly, his passenger, an 18-year-old man, died at the scene.
