A man was found in the middle of the road with serious injuries to his head, chest and limbs at Gladstone on the coast of Queensland, south of Rockhampton.
The 58-year-old man was found by a motorist passing in the middle of Red Rover Road in Callemondah around 19.15 on Sunday, Queensland Police said in a statement.
He was declared dead at the scene.
The man's car was found off the road with significant panel damage but police did not believe the damage was consistent with a 58-year-old injury.
Police believe the man might have walked along the road when he was hit by a passing vehicle and begged anyone who had information to contact the police.
