The rescue chopper was called to the accident site just before 6pm.
It’s believed the two people, both aged in their forties, were the only two people travelling in a hatchback, which lost control and crashed into a tree.
Queensland Ambulance Service (QAS) paramedics, Queensland Fire and Emergency Service (QFES) personnel and Queensland Police Service (QPS) officers were all on the scene, when the aeromedical team arrived.
The chopper was able to land around 200 metres from the scene.
RACQ LifeFlight Rescue’s Critical Care Doctor and QAS Flight Paramedic assisted with treatment of the patients, while they were freed from the wreckage by firefighters.
After the patients were cut free from the vehicle, they were loaded into the RACQ LifeFlight Rescue helicopter and flown to Toowoomba Hospital.
The male driver and his female passenger were both in a serious condition.
