An evacuation order has been issued for residents in parts of the New South Wales local government area of Singleton.

The NSW State Emergency Service (SES) is directing people along the Hunter River within Whittingham, Scotts Flat, Glenridding, Dunolly and Combo areas to evacuate the high danger area by 7pm.

Once floodwaters pass 11 metres on the Singleton gauge at Whittingham and Scotts Flat, roads will begin to close.

The areas affected include Whittingham, Scotts Flat, Whittingham Hall via New Freugh Hill via New England Highway and Range Road, Glenridding, Dunolly and Combo.

"Once floodwater begins inundating the area, road access water, sewerage, power, phones and internet may be lost," an SES spokesperson said.

"If you remain in the area you will be trapped and it may be too dangerous for SES to rescue you.

"Wherever possible, people should go and stay with family or friends, or make other accommodation arrangements."

If residents are unable to do this, an evacuation centre has been set up at Alroy Complex, Dorsman Drive, Singleton Heights.

Residents in low-lying properties have been advised to lift possessions and important items above the predicted flood height.

They should take pets, essential items, warm clothes, medicines, insurance documents and valuables with them.

"Leave as early as possible to avoid restricted roads," a spokesperson said.

"Share this information with family, friends and neighbours and help others where possible."

As wet weather continues, flood warnings are in place for New South Wales and Queensland after heavy rainfall overnight.

It comes as the two states received more than a month's worth of rain in a day.

The deluge has caused Sydney's Warragamba Dam to hit capacity and begin to spill.

The dam began spilling just after 9pm last night.

The spill is expected to continue for a week or more.

Hazardous conditions

The weather has turned deadly after a man was killed in central Queensland.

The man's ute was swept away by floodwaters in Hibernia, west of Rockhampton in central Queensland.

The heavy rainfall and wild weather has caused damage to NSW roads.

A bridge collapsed in the NSW Central West as a result of the deluge.

A car was driving over the Nyrang Creek Bridge near Canowindra as it was collapsing.

The occupants were taken to hospital and were not in a serious condition.

NSW Premier Dominic Perrottet has urged residents to pay attention to weather and flood warnings.

"We've had over 34 flood rescues in the last 24 hours that is way too many," he said.

"Please don't drive through floodwaters, please follow the advice you've been given. That will keep you and your family safe."

The NSW State Emergency Service (SES) received more than 850 calls for help overnight and performed 34 flood rescues.

There are flood warnings in place for NSW inland rivers, and the Hunter, Hawkesbury Nepean Rivers.

Minor flooding is expected for the Hawkesbury Nepean River this afternoon.

It comes just months after the region was hit by devastating floods which destroyed homes and businesses.

Scone in the state's Upper Hunter region has been hit particularly hard with residents told to prepare for evacuations.

In Queensland, there are flood warnings in place for the Dawson River and Theresa Creek.

Australia's east coast has been battered by a weather system that stretches across four states as the November deluge continues.

Ukrainian President Volodymyr Zelenskyy on Friday claimed his country's intelligence service has uncovered plans for a Russia-backed coup d'etat in the country set for next week that allegedly involves one of Ukraine's richest oligarchs.

Both the oligarch and the Russian government rejected the allegations.

At a news conference in Kyiv, the Ukrainian capital, Mr Zelenskyy said he received information a coup was being planned for next Wednesday or Thursday.

He did not give many details to back up his allegation, but pointed to a suspected role of Ukraine’s richest oligarch, Rinat Akhmetov.

The president said Ukrainian intelligence has audio recordings of an alleged meeting between Russian and Ukrainian officials discussing a plan for a coup allegedly funded by Mr Akhmetov, whose fortune is estimated at $10.5 billion.

Mr Zelenskyy refused to disclose further details about the alleged coup, saying only that he doesn’t plan to flee the country.

Kremlin spokesman Dmitry Peskov rejected the allegations in comments to journalists in Moscow on Friday.

READ MORE: Fears mount over Russian invasion of Ukraine

“Russia had no plans to get involved," Mr Peskov said. "Russia never does such things at all.”

Mr Akhmetov called Mr Zelenskyy's allegations "an absolute lie".

“I am outraged by the spread of this lie, no matter what the President’s motives are,” Mr Akhmetov said in a statement, relayed to the Associated Press by his spokeswoman Anna Terekhova.

Asked about the alleged coup plans, the US State Department’s top official for European and Eurasian affairs, Karen Donfried, said: “We are in touch with the Ukrainian government to discuss this further, and we’re working to obtain additional information.”

Volodymyr Fesenko, a Kyiv-based political analyst and head of the Penta Center think tank, told the AP that Mr Zelenskyy targeted Mr Akhmetov after a “proper information war” was waged against the president over the last two months on TV channels the oligarch owns.

A mass protest in front of the president's office is also being planned for December 1.

The analyst pointed to great discontent among Ukrainian oligarchs, including Mr Akhmetov, over a law pushed by Mr Zelenskyy that limits their influence on politics.

Mr Fesenko called Mr Zelenskyy's reference to Mr Akhmetov in connection with the alleged coup "a pre-emptive signal" for the oligarch not to get in involved in "risky political ventures, cross the ‘red lines' and negotiate with Moscow".

In recent weeks, Ukrainian and Western officials have expressed concern that a Russian military buildup near Ukraine could signal plans by Moscow to invade its ex-Soviet neighbour. The Kremlin insists it has no such intention and has accused Ukraine and its Western backers of making the claims to cover up their own allegedly aggressive designs.

Mr Zelenskyy said Ukraine has full control of its borders and is ready for any escalation of the conflict with Russia. But he noted that the media are engaged in fear-mongering over the possibility of such a conflict.

He also said that the head of his office, Andriy Yermak, will soon be in contact with the Russian authorities at the request of the European Council President Charles Michel and German Chancellor Angela Merkel.

“They want contacts between our administration and the Russian administration. I think that in the near future Yermak will contact them. We are absolutely not against [this]," Mr Zelenskyy said.

A person has tested positive to COVID-19 in the Northern Territory after arriving from South Africa.

Genomic sequencing is underway to determine whether it is the Omicron variant, which has been classified as a "variant of concern" by the World Health Organisation (WHO).

"We don't have the genomic sequencing of that case yet but that would be undertaken in the coming days," Northern Territory Health Minister Natasha Fyles said, adding the person is in Howard Springs quarantine facility and poses a "low risk" to the community.

The case is one of two in the Territory in the past 24 hours, with the other a man in his 50s from Katharine.

He is a household contact of previous cases.

"Katherine will be lifting, as of a midday today, to a lockout as opposed to a lockdown," she said.

"Anyone who is fully vaccinated in the Katherine region is now free to go about their daily business. They will need to wear a mask and we do encourage of course you do check-in as you go out and about."

Fully vaccinated residents are free to travel to Darwin and go to other high-vaccinated areas within the territory, but they will have to fill out an application.

The unvaccinated will remain in lockdown.

Binjari, near Katherine, will remain in hard lockdown with further testing to be completed on Monday.

Ms Fyles said a 27-year-old man who absconded from Howard Springs during a "significant storm" yesterday afternoon was caught around 10pm last night.

He has tested negative to COVID-19.

"I'm extremely disappointed in the incident that took place," Ms Fyles said.

"The man absconded on day 13 of his quarantine period, so he was extremely low risk, but nonetheless that is not acceptable and police are fully investigating the matter."
