FISHERMEN, boaties and swimmers beware; it is crocodile nesting season and the "good mums" guarding their eggs are not taking any prisoners.
Koorana Crocodile Farm owner John Lever said reported sightings of crocodiles in developed waterways were common during times of low rainfall and the community should take caution.
He said the drought and a lack of fresh water was pushing crocodiles into developed waterways in the search of fresh drinking water, but the current nesting season meant female crocodiles were particularly dangerous.
"Sightings are connected to a lack of fresh water, they are coming up to the barrage and the sewerage treatment plant to get a drink," Mr Lever said.
"But it's also nesting season so people need to be more conscious especially around nesting females because they can be very dangerous animals, because she's being a good mum."
He said reported sightings were most likely saltwater crocodiles, which can only drink fresh water.
Rockhampton fisherwoman Julie Johnson said she saw a 2.7m crocodile swim past her while she was fishing on the Fitzroy River last week.
"The tide was down a bit so we were up high and he was just going past, really close to the barrage," she said.
Crocodile sightings should be reported to CrocWatch at ehp.qld.gov.au.
The site has received two unconfirmed crocodile sightings this month, one at Emu Park and the other at Gracemere.
