Queensland's flood emergency claims its first life

Queensland's flood emergency has claimed its first life - with a man's body pulled from floodwater at Eagleby this afternoon.

Three other people remain missing since the flood crisis began.

In Logan, 250 homes have water through them - another 30 in Beaudesert and many hundreds more are cut off.

Almost 17,000 homes are still without power and the clean-up is yet to begin.

Since the system moved south there have been more than 110 water rescues in the South East and 3,100 calls for help - to the SES.

The full extent of the damage won't be known until the flood water subsides.

"I just urge all residents to in those areas to please to continue to heed the official warnings," Queensland Police Commissioner Ian Stewart said.

Police have confirmed three people have died in the floods in northern New South Wales.

Thirty thousand people were under evacuation orders and there were more than 400 rescues.

Cameras were there as a man who had been stranded on the Gold Coast for two days managed to swim to safety through floodwater.

Karl Chaney had spent 48 hours alone on a boat and realised the only way out was to swim.

"I couldn't get off, choppers couldn't get in, boats couldn't get to me," Karl Chaney told 7News.

He made it to safety with only a bucket of belongings, and was exhausted and hungry when he emerged.

"I put work boots on, look, just in case there was something sharp down there," Mr Chaney said.

There were also extraordinary pictures as residents rescued a stranded kangaroo with a kayak on the Albert River.

"All we could see was his little nose and ears, and he was, exhausted," Susan Pepperell from Albert River Bed and Breakfast told 7News.

Also in South East Queensland, customers of the iconic Yatala Pies shop turned up to help with the clean up, after the business was surrounded by water on Friday.

"Hopefully with the people helping today, we're going to be back up running next week."
