Wildlife officers are investigating a sighting of a three-metre crocodile near a northern Brisbane beach.
Department of Environment and Resource Management (DERM) wildlife director Nick Rigby said a fisherman spotted the croc on Thursday in the Schultz Canal heading up Jacksons Creek, near Nudgee Beach.
"The observer was confident that it was a crocodile around three metres long," Mr Rigby said in a statement.
"Staff carried out a survey by boat today, but saw no sign of a crocodile.
"They will be doing a survey this evening using spotlights."
He said 'recent crocodile sighting' signs had been put up in the area as a precaution.
"It would be highly unusual to see an estuarine crocodile south of the Boyne River near Gladstone, but it's not impossible," Mr Rigby said.
"Although a large crocodile was taken in the Logan River about 100 years ago, there has not been a single confirmed sighting of an estuarine crocodile in the wild south of the Boyne River near Gladstone since then.
"Apart from the possible but unlikely presence of a crocodile, there is always the potential for sharks to be in the area and people fishing, boating and swimming should always exercise appropriate caution
