A romp in the swamp is caused by low flying helicopters!
The owner, John Lever, of the Koorana Crocodile Farm, located just outside Rockhampton, manages a sizeable collection of over 3,000 crocodiles. He possesses a natural knack for discerning the signs of impending romance among them.
Thunderstorms are an aphrodisiac for a croc according to Mr Lever.
Male crocodiles might misinterpret the sound of a helicopter as a rival bull, causing them to hurry to secure their reproductive success before this imagined competitor can act upon its amorous intentions.
