Premium Content Subscriber only Predicted rain is set to send frisky female crocodiles into a nesting frenzy prompting warnings for the public to be vigilant around waterways this summer holidays. Two of the dangerous prehistoric reptiles have been captured in the past month in the Fitzroy River at Rockhampton by the Department of Environment and Science DES. The DES crocodile sightings dashboard shows 99 recorded sightings in the past 30 days in Queensland from Hervey Bay to Cape York. Following rain earlier this week, Koorana Crocodile Farm was a hive of activity. Owner John Lever said the rain triggers the females into nesting behaviour.
