Nine-year-old girl among several flood victims in Australia's Queensland

A nine-year-old girl is the latest victim following severe storms across eastern Australia this week.

Queensland police said the girl's body was recovered from a storm drain in Rochedale South on Tuesday night, after a major search.

Kevin Walsh of Queensland's Fire and Emergency Services (QFES) said circumstances are unclear around the death.

"The young child went missing behind some properties… and a short time later we found the young girl deceased some way down from where she went into the water."

Authorities said on Wednesday nine people have now died and one is missing after the storms - up from six on Tuesday.

Who were the victims?

A couple of victims have now been officially identified.

One of the victims was David 'Mario' Logan, who was a rugby-mad bloke from Brisbane.

"In a club that has so many stalwarts and legends, "Mario" was right up the top as one of Brothers' most favourite son," said Geoff Rodgers, president of the Brothers Rugby League Club.

Another was Steve Tait, a school teacher from Brisbane.

Emergency workers recovered one victim after a boat capsized in Moreton Bay, with 11 on board.

Authorities fear two more people could have died in that accident.

Another person was found dead in the waters off the coast of Brisbane.

Residents further south in Victoria didn't escape the worst of the weather either.

A woman was found dead in Buchan on Wednesday, after floodwaters receded from a campground.

Two other women were swept away while "exploring" a storm drain in Gympie on Tuesday afternoon, police said.

Queensland's Acting Superintendent Paul Algie said they were with another woman, and all three were "washed" out to the Mary River - but one survived and managed to raise the alarm.

7News reported a woman, 59, was killed after being struck by a tree on the Gold Coast on Monday.

Do residents have power yet?

As the floodwaters receded, thousands of people remained without power as more than 1000 power lines were brought down since Sunday across the region.

Energex said it's trying to restore power to about 85,000 people in southeast Queensland.

Spokesperson Justin Coomber said it would take days to reconnect everyone.

"We've seen those 30-metre-tall concrete poles snapped in two," Coomber said.

"We've never seen that before."

'Lucky to be alive'

Victoria police said a woman and her dog are "lucky to be alive" after being rescued from the Werribee River, Melbourne on Tuesday.

Madi, 29, was swept away while trying to retrieve her Minka from the river.

"She's never gone in the river before and she chose yesterday, when it was really full and flowing very rapidly, to decide to go in," she told ABC News.

They waited on a small island until rescue crews arrived.

Meanwhile, in New South Wales, the State Emergency Service (SES) responded to more than 190 calls for help.

SES workers have carried out nearly 40 rescues since Sunday, in areas like Tathra, Lake Bathurst, and Bega, among others.

Hail and flooding had caused widespread damage across the state.

SES spokesperson Stephanie Heard said several flood rescues involved people stuck in their cars as waters rose.

"We're really urging people again … to really plan and take care in the environments you're in."
