EX-TROPICAL cyclone Oswald is causing havoc across Queensland's southeast with 2000 calls for help and many rescues overnight.
The SES received more than 1800 requests for assistance in the 24 hours to 4am today.
More than 830 of these jobs were concentrated in the North Coast region, particularly around the flooded city of Bundaberg, where hundreds of homes and businesses have been inundated.
There were more than 550 jobs in the South East region, particularly around the Lockyer Valley, Laidley and the Gold Coast.
Brisbane also recorded a large number of requests for SES assistance, most commonly for leaking roofs, floodwater threatening property, sandbagging and fallen trees.
Queensland Fire and Rescue Service duty manager Richard Gory says rain and gale force winds have uprooted trees across the region, brining down powerlines and flooding homes and streets overnight.
He says every available officer is on duty, and the fire service alone has responded to 590 calls for help, including 239 in the Brisbane region.
Overnight swift water rescuers gone have to the aid of people in flood-hit communities across the state, including in Brisbane, the Lockyer Valley and Bundaberg.
In one Brisbane rescue, 24 people were rescued in the Windsor area as waters rose there.
Emergency alerts were issued overnight for Moreton Bay, Somerset and the Lockyer Valley.
Police are still trying to confirm reports a man was swept away in floodwaters in Arana Hills on Brisbane's northside.
And a search was due to resume at first light in Logan, south of Brisbane, for a motorcyclist who was swept off a flooded road on Sunday night.
"He's made an attempt to cross that water, the water has been running too quickly and unfortunately he has been swept by the force of the water into a very swollen creek," a police spokeswoman told ABC radio.
"He tried to anchor himself on his motorcycle, however the people who were there tried to throw him out a rope and when he's attempted to grab the rope he has unfortunately let go of the motorcycle and the water has taken him."
