A spokeswoman said paramedics were still assessing the victim, but that they expected to be taking them to hospital for treatment soon.
A central fire communications spokesman confirmed they got a call about 12.12pm that a person was inside a vehicle in the water at Bell Block Beach.
Despite that information, he said it was "not deep" and acknowledged that it was not thought the person inside was in any danger.
He said authorities had been told that only one vehicle was involved.
The circumstances of the incident are not yet known.
