UPDATE, 7.32AM Killarney police have confirmed five hikers reported missing on Mt Superbus last night were located safe and sound.

Senior Constable Adam Fox said he received a call about the hikers just after 6pm.

"My job was to firstly go and locate their vehicle," he said.

"To make sure they weren't at the car, with something like a flat battery or no phone service, that kind of thing.

"If I had been unable to locate then, at that point I would have organised a search party.

"But as I reached the Mt Superbus carpark at about 7.30pm, they were already in their car and leaving the mountain.

Snr Const Fox said the hikers were simply overdue.

"They were a little surprised police had been called," he said.

"The leader of the hike was very experienced and they had all the right gear with them, personal beacons etc.

"They had just taken a little longer getting down the mountain than they had anticipated.

"They were all fine with no injuries."

EARLIER, 6.40pm:  POLICE have sent a crew to locate the car used by hikers thought to be missing at Main Range National Park. 

Warwick police sergeant Lisa Self said the group of five hikers - two men and three teenage boys - were yet to activate a flare or EPIRB in their possession. 

"We have sent a crew to see if they can locate the car from the base of the track up to Mt Superbus," Sgt Self said. 

"If the car is still there we would have reason for concern." 

EARLIER, 5.50pm: AT LEAST five people are believed to be missing in Main Range National Park this evening. 

An informant has reportedly contacted Warwick police about the hikers - two men and at least three boys - who set out yesterday to scale Mt Superbus.  

The group are believed to have begun their trek from the  Emu Creek Road side of the National Park and scaled the mountain to see the crashed Lincoln Bomber on the mountain. 

They were reported to have camped overnight and were expected to return at about 3 this afternoon. 

Initial reports said one of the men was thought to have had a flare and Emergency Position Indicating Radio Beacons.
