Four people have been killed in three separate crashes in five hours on country roads in NSW.
Two people died after two cars collided head-on in near Euston in western NSW about 6.45am on Sunday.
Police said a utility and sedan collided on the Sturt Highway about 6.45am on Sunday. The female driver of the utility died at the scene. A man, travelling as a passenger in the sedan, also died.
Just minutes earlier, a duck on a country road in Tamworth caused a crash that killed a 19-year-old woman passenger about 6.40am on Sunday.
The car hit the duck on the road, and then crashed into a tree, police say. The woman, from Quirindi, died at the scene.
A 52-year-old man died when he swerved to avoid hitting a dead kangaroo near Tumut in southern NSW in the early hours of Sunday morning.
After swerving, the man's car left Gocup Road and caught fire, police say.
Emergency services were notified about 2.30am when the man failed to arrive at work for his shift.
"These tragedies should serve as a reminder of the need for road users to anticipate unexpected hazards such as animals and slowing down if you are not used to driving on dirt or gravel roads," Assistant Commissioner Michael Corboy said in a statement on Sunday.
