The man suffered serious injuries and died in hospital on Sunday morning.

Debris found at the crash indicated the car involved was a purple sedan or utility, possibly a Ford, a police spokesman said.

The car police believe to be involved was found abandoned, with no registration plates, on the outskirts of Rockhampton, just before 11am Sunday.

Police have appealed for the driver of the car or anyone who may have witnessed the tragedy to come forward.
