Crews fight fire after two badly injured in plane crash

The two people on board the plane suffered life-threatening injuries, Queensland Ambulance Service said.

The wreckage caught alight on impact, sparking a fire in bushland about 500 metres from the airstrip.

A large plume of smoke can be seen kilometres from the crash site where about a dozen emergency services crews are on the scene.

The plane is believed to have gone down in thick bushland, making access difficult for the ambulance, police and fire crews.

Queensland Ambulance Services said a pilot and a passenger were involved in the crash.

Queensland Police were set to provide an update at 10am AEST.
