Two dead in crash to avoid man on highway

A teenage girl and a 47-year-old man have died after their 4WD swerved to avoid a man standing on a highway in Western Australia's far north.

The car, which was carrying six people, lost control and rolled on the Victoria Highway near Kununurra on Thursday night, police say.

The driver died at the scene while his 14-year-old passenger was taken to hospital, where she died a short time later.

A man in his early 20s suffered serious injuries and was flown to Perth while three other passengers - aged 17, 13 and three - received non-serious injuries.
