Police have been asked to investigate reports a rescue helicopter was put in danger by tourists on Fraser Island this week.

The crew of the AGL rescue helicopter was preparing to land near Orchid Beach when a group of four wheel drivers aimed their high powered spot lights at the aircraft.

Chief Executive David Donaldson says the crew was responding to an emergency when the incident happened on Wednesday night.

"The actions of the people in this vehicle were really preventing us from doing our job," he said.

"These guys were shining lights at the helicopter to potentially blind the crew and certainly distract them away from what their task needs to be - which is making sure the helicopter got on the ground safely so we can get medical care to the patient.

"If they had been in a critical phase of flight or close to obstacles it may have distracted them sufficiently to cause quite a catastrophic problem."

Mr Donaldson says the crew and the patient were put at risk and the helicopter could have crashed.

He says the AGL helicopter has flown to Fraser Island 16 times since Christmas rescuing more than a dozen people with serious illnesses and injuries.
