CareFlight medical teams flew six injured men to hospital from overnight car crashes which left another man dead off the remote Buntine Highway 500km south of Darwin in the Northern Territory.

Nurses from the health clinics at Kalkarindji and Lajamanu and local police rushed to the initial crash at Waylong Creek, almost 70km north-east of Kalkarindji, before a CareFlight doctor and flight nurse were called to fly the man to hospital in Darwin.

The medical teams treated the 28-year-old man for multiple injuries suffered when he was ejected from the vehicle as it rolled shortly before midnight.

They took the man back to the Kalkarindji Health Clinic for treatment until CareFlight flew him to Royal Darwin Hospital where he remained in a serious but stable condition on arrival at 8.30am.

The two were the only occupants of the car which police said brought the Northern Territory road toll to eight this year.

Police and nurses from the clinics were later  called to treat another eight men when two vehicles crashed head-on less than 2km from the initial rollover.

All the occupants managed to free themselves from the vehicles which then caught fire.

Nurses stabilised the injured at Kalkarindji Health Clinic.

CareFlight sent two aircraft, from the aeromedical charity’s bases in Darwin and Gove, to fly the additional five men to Royal Darwin Hospital.

Two of the men remained in a serious condition and three were in a stable condition on arrival in Darwin late today.
