Two men from Harristown, Toowoomba, died following a single vehicle traffic crash in McKinlay on Friday morning.
Just after 7:30am, a car was travelling along the Landsborough Highway, 200km south of Mount Isa, when it lost control and rolled into a ravine.
The 26-year-old male driver and the 33-year-old male passenger, both from the Toowoomba suburb of Harristown, were both pronounced dead at the scene.
The second passenger, a 37-year-old male from Charleville, was transported to hospital.
Mount Isa's RACQ LifeFlight Rescue helicopter airlifted the survivor from the crash scene.
The man told rescuers he had been on a journey from south west Queensland, to the north west.
The man was flown to Cloncurry Hospital, suffering suspected upper body injuries, in a stable condition.
The Forensic Crash Unit is investigating.
