The Sydney Morning Herald is reporting that Brisbane's roads are filling with workers seeking to flee the city as the Brisbane River (pictured right in dryer times) breaches its banks at multiple locations.
Roads are crowded and thousands of people are flocking to use public transport as the CBD empties, the report continues.
Brisbane Airport remains open. There have been reports that buildings in the neighboring suburb of Pinkenba are taking water and residents have been urged to seek higher ground.
Meanwhile, a severe weather warning has been issued for much of south-east Queensland, including Brisbane and the south-east coast, Darling Downs and the Granite Belt south-east of Dalby to Goondiwindi.
The Bureau of Meteorology is warning of heavy rainfall causing localised flash flooding and worsening the existing river flood situation.
