Police have confirmed a man in his 70s was found dead inside a vehicle submerged in floodwater at Normanton in north west Queensland.

Officers were called to Gulf Development Road around 3pm on Tuesday afternoon where they found the man's body in the vehicle.

"The death has not been deemed suspicious and a report will be prepared for the coroner," a Queensland Police Service spokesperson said.

Mount Isa District Acting Superintendent Paul Austin said the death was a tragedy.

"This is a tragic event, and just highlights the message that police continue to push out. Don't drive through floodwaters," he said.

"Use the information at hand and the resources available, plan your journey, turn back if needed and if it's flooded, forget it"
