North-eastern Australia's worst flooding in decades is continuing to cause chaos across the region.

About 1,000 people in Queensland have been evacuated, including the entire population of the town of Theodore.

The government has declared Theodore and two other towns in the region to be disaster zones, and forecasters say the floods have not yet peaked.

The cost of the damage is expected to top AU$1bn (£650m), including massive losses of sunflower and cotton crops.

Army Black Hawk helicopters evacuated the 300 residents of Theodore, where every building in the town apart from the police station has been flooded, local media reported.

Theodore county mayor Maureen Clancy said only a few police officers had stayed behind.

"Certainly the water is still rising. The heights are at such a new record it's not known what this is going to do," she said.

The town's river has risen more than 50cm (1.6ft) above its previous recorded high, Emergency Management Queensland spokesman Bruce O'Grady told Australia's ABC News.

Theodore farmer Keith Shoecraft told the BBC that vast areas of farmland were under water.

"This has been devastating for our town. Tonight that town will be completely isolated, empty," he said.

Mr Shoecraft said many farmers had stretched themselves financially but would be determined to survive.

"They're a pretty tough lot here, they won't leave. If... their bank managers will keep giving them money they will keep trying and trying and trying."

In the city of Bundaberg, residents in some areas were being advised to leave their homes as the Burnett River rose to danger levels.

The river was expected to reach 7.5m - about 0.3m more than the previous high water record of 1954.

In the Central Highlands town of Emerald, flooding forced the closure of the main bridge, cutting the town off, Australian media reported.

Brad Carter, the mayor of Rockhampton, warned that his city and more remote surrounding communities could be cut off by the weekend.

The floods are also hitting businesses in Queensland, which is Australia's key coal-producing state.

Two of Australia's biggest coal export terminals - Dalrymple Bay and Gladstone Ports - together with Australia's top coal transporter QR National said they were cutting back on operations while the floods persisted.

Rio Tinto Group, the world's third-largest mining company, declared "force majeure" at four Queensland coal mines allowing it to miss deliveries because of circumstances beyond its control.

Peter Maguire, mayor of Emerald Shire, told the BBC's World Today programme the floods would have a huge economic impact on agricultural areas.

"There will be many, many cattle drowned. It will be devastating, fences are down on properties as well as farming land. Cotton... and lots of other crops will be affected."

Disaster fund

Inland towns such as Chinchilla and Dalby are all under water; the nearby town of Warra, and the towns of Alpha and Jericho, west of Emerald, have also been declared disaster zones, with hundreds of homes flooded or at risk.

Media reports said Dalby was running low on drinking water supplies after its water treatment plant was damaged by the floods.

Queensland Premier Anna Bligh launched a disaster relief fund with AU$1m in state money and Australian Prime Minister Julia Gillard pledged to match the amount with federal funds.

"Some communities are seeing floodwaters higher than they've seen in decades, and for some communities floodwaters have never reached these levels before [in] the time that we have been recording floods," Ms Gillard said.

"For many communities we haven't even seen the peak of the floodwaters yet, that's a number of days away."

The state capital, Brisbane, has recorded its wettest December in more than 150 years. Cyclone Tasha, which hit Queensland on Saturday, also brought torrential rain to the state.

Long traffic queues have formed outside isolated towns and police are arresting people who need rescuing after driving into badly hit areas, says the BBC's Steve Marshall in Sydney.

Further south, in New South Wales, about 175 people who had spent the night in evacuation centres have returned home.

But 800 people in the towns of Urbenville and Bonalbo are expected to be cut off for another 24 hours.

While the rain is now easing, water is continuing to flow from sodden land across central and southern Queensland into already swollen rivers, adds our correspondent.

Queensland's Emergency Services Minister Neil Roberts told ABC the worst was yet to come.

"Over the next 48 hours rain will be easing but the real impact in some communities won't be felt for a couple of days when floodwaters begin to recede," he said.

"Once the rain finishes there will still be significant flooding impacts over the next few days."

Farming groups says the floods could devastate crops, badly hitting an industry which was already suffering the effects of a lengthy drought.

Cotton Australia said that about 7,500 hectares of the crop planted near Theodore had been destroyed.
