Six people have been left with life-threatening injuries following a horror crash in North Queensland.

A bus collided with a car towing a caravan along the Bruce Highway south of Burdekin at 12.50pm on Sunday.

Some 33 people were on the inter-city bus travelling between Bowen and Townsville. Two people were in the car that was towing the caravan.

Six were left critically injured while 29 have been treated by paramedics at the scene. 

A Queensland Ambulance Service spokeswoman said the scenes at the scene of the collision were chaotic for emergency responders, including paramedics.

Two rescue helicopters have also been tasked to the scene. 

Queensland Police said they were called to the Wilson Creek Rest Area just after 11am, following reports of a serious crash. 

The Bruce Highway is closed in both directions at Gumlu. 

Motorists travelling between Ayr and Bowen are being urged to avoid the area or expect long delays.
