Two dead in overnight crashes on Qld roads

Two men have died in separate crashes on Queensland's roads overnight while a third man is hospital with non-life threatening injuries to his abdomen.

A 30-year-old rider was killed about 1am on Sunday after his motorbike crashed into a guard rail on the Gateway Motorway near Belmont, south of Brisbane.

A man in his 20s died when his car collided head-on with a semi-trailer on the Burnett Highway near Gayndah about 11.20pm on Saturday, also injuring the truck driver who was taken to Bundaberg Hospital.
