An 18-year-old woman and a tourist, believed to be from Victoria, are dead after two seperate car crashes in the Townsville region.

A young woman is dead and a teenage boy is clinging to life after a group of youths allegedly crashed a stolen car in north Queensland.

Police say the sedan was stolen from a house at Rasmussen, in Townsville, shortly before it smashed into a tree and a parked vehicle, killing the 18-year-old driver.

A boy, 14, remains in a critical condition, while two other teens are recovering from non-life-threatening injuries from the crash at Cranbrook early on Tuesday morning.

Acting Inspector Graeme Paterson says police are investigating reports that up to three youths fled from the scene.

The crash was so severe that the car snapped a tree and overturned a large parked vehicle.

Insp Paterson described the consequences as tragic.

“This is a tragedy no matter what way you look at it,” he told reporters in Townsville.

“We have the loss of a young person’s life … and another young person fighting for their life.”

The woman was one of two motorists who died in the Townsville region overnight.

A holiday turned to tragedy when a vehicle reversed over a man on Fletcher Vale Road, about 60 kilometres north of Charters Towers, between 8.30pm and 9.30pm (AEST).

Acting Insp Paterson says the man was travelling with two others when he stepped out of the vehicle, which then reversed over him.

“They made attempts to provide assistance to him and take him back to Charters Towers Hospital but he died,” he said.

The men were believed to be holidaying from Victoria.
