The weather bureau says the rain lashing the central Queensland city of Mackay is causing the worst flood to hit the region in more than 20 years.
A disaster situation has been declared in the Mackay region and locals are being told to stay inside.
The situation is worsening in Mackay as four ABC staff members are among hundreds of people trapped waiting for State Emergency Service (SES) boat crews to take them to safety.
Businesses and schools are closed, rescue helicopters have been grounded and earlier, two people were saved from the roof of their car.
The weather bureau says there have been falls of more than 100 millimetres an hour, for several hours.
