Crocodile warning signs at Woodgate were erected because an unconfirmed sighting was reported to the Department of Environment and Science.
A DES spokesman said a crocodile sighting report was from a member of the public via wildlife officers.
Temporary warning signs were installed on Friday and later removed on Monday as the report couldn’t be confirmed.
There have previously been unconfirmed crocodile sightings from the Woodgate area, including Theodolite Creek, in recent years.
A DES spokesperson said wildlife officers were advised that a member of the public saw what they thought to be a crocodile offshore.
Members of the public are encouraged to report crocodile sightings as soon as possible by calling 1300 130 372. DES investigates all reports it receives. DES takes all reports of crocodiles seriously.
Crocodiles that pose a threat to human safety are targeted for removal under the Queensland Crocodile Management Plan.
While crocodile habitat is recognised as being north of the Boyne River, estuarine crocodiles are found south of the Boyne in the Mary River (southern-most confirmed crocodile) and Fraser Coast down to Tin Can Bay, where there have been numerous unconfirmed sighting reports by locals and commercial fishers.
