WILDLIFE officers are still searching the Mary River for a crocodile after two more sightings this year.
A Department of Environment and Heritage Protection (DEHP) spokesperson said the crocodile was estimated to be 3.5m in length, but its gender was unknown.
A member of the public reported seeing the crocodile at Emery's Bridge near Gundiah on January 2, before another sighting at freshwater Tinana Creek on January 11.
Officers last surveyed the Mary River system by boat on March 23, but found no trace of the animal.
"Efforts to remove the remaining crocodile are continuing," the spokesperson said.
If caught, the crocodile will be relocated to a crocodile farm or zoo.
DEHP first received reports of a crocodile in the Mary River in 2012, before a second crocodile was identified in July 2013.
In November 2013 a 3.1-metre crocodile was removed.
Crocodile sightings can be reported to DEHP on 1300 130 372.
