A 45-year-old Kingaroy man was airlifted from Rockhampton Hospital to the Royal Brisbane Women's Hospital with serious head and spinal injuries after the cattle truck he was in overturned.
The incident occurred on Lowestoff Rd at Tieri about 3pm on Thursday.
The man was flown to Brisbane in a serious but stable condition and the aircraft arrived late yesterday.
He was the driver of the semi-trailer and was thrown clear of the cabin, authorities said.
The truck had two occupants.
The passenger suffered less serious injuries and was taken by road to Emerald Hospital.
Initial police reports indicated that the cattle truck had gone off the road shoulder and rolled onto its side.
The driver had just picked up a load of cattle for transport from a nearby farm, and failed to negotiate a bend in the road.
A number of cattle were killed in the accident, and several others had to be put down by the owner, who went to the site after hearing of the accident.
The Forensic Crash Unit was investigating the accident.
RACQ Capricorn Helicopter Rescue (Rescue 300) was sent to the accident site and landed on the road close by.
A Queensland Fire Service vehicle blocked traffic to provide a suitable landing zone and the helicopter was then able to put down on the asphalt road surface.
The road was blocked for some time.
