Locals will remain in the dark over mysterious late-night helicopter flights buzzing over Caloundra.

The Aura Post’s attempts to uncover who’s behind the mystery of low-flying helicopters spotted on FlightRadar24 were shot down when no one fessed up.

Some apps identify the helicopter as a Surf Lifesaving Rescue chopper, but the official word from Surf Lifesaving Queensland is that the activity was Polair – the police air wing used by law enforcement agencies across Australia.

However, queries to Queensland Police revealed there was no Polair activity registered in the area during that timeframe.

Enquiries to Council, which oversees Caloundra Aerodrome, revealed emergency service choppers can fly as needed, casting doubt over the accuracy of flight details on the apps, above all else.
