UPDATE: A Brisbane man bought his son a Honda motorbike on Friday.
The next day the father watched in horror as emergency services scrambled to recover his 35-year-old son's body after the bike he was riding and a 4WD collided.
His son was killed instantly when his Honda motorcycle veered onto the wrong side of the road on the Capricorn Hwy, at Gogango.
The son collided with the 4WD Toyota which was towing a caravan, on an open, left-hand curve at the bottom of the Gogango range, about 46km from Duaringa.
Rockhampton Police Regional traffic co-ordinator Inspector Mike Curtin said the 35-year-old's father was riding a motorcycle slightly ahead of his son before the accident happened.
He said the pair were headed west.
Police said the accident took place about 11.35am.
The road was blocked for more than five hours as emergency services from Rockhampton and Gracemere tended to the scene.
A 65-year-old man and a 61-year-old woman were the occupants of the 4WD and were not injured.
They, along with the dead rider's father, were treated by ambulance staff for severe shock. A Queensland Ambulance Service spokeswoman said the man died of multiple injuries.
Inspector Curtin said the circumstances around the accident were "traumatic".
He said it was believed the father and son entered the Capricorn Hwy via the Leichhardt Hwy.
"It was an unfortunate accident and we plead with the broader community to keep a focus on road safety with a view to addressing the amount of deaths on our roads in Central Queensland and other areas," he said.
The man was from the Brisbane suburb of Capalaba.
Police said the motorcyclist's family did not want to release the man's name at this stage.
