Two Royal Australian Air Force planes are ready to depart for Tonga as soon as conditions allow, with the flights waiting for ash to be removed from the Pacific nation's airport runway.

New Zealand Defence Minister Peeni Henare said he was informed the Tongans were redoubling their efforts to clear the runway and have it operational by midday to early afternoon on Thursday.

Mr Henare said locals were removing the dust by hand because small equipment had been destroyed or can't be used.

"I've been told it is human power that is sweeping clear the debris and the ash off the runway at the moment," he told the ABC.

"My understanding is that, with respect to the airport, the ash cover is significant, but not overwhelming."

One unconfirmed New Zealand defence report said the ash was up to a metre deep in some places, Mr Henare said.

"The most stark description that was given to me in the briefing from the defence force was the lack of colour," he said.

"You imagine Pacific Islands, the tropical nature of the place and the bright colour of the sands and beaches. It's all very grey and dull because of the ash that just blankets the entire land."

Australia's HMAS Adelaide is preparing for deployment after arriving in Brisbane on Wednesday and has been loaded with humanitarian and disaster relief supplies, along with critical equipment to help recovery efforts.

It's expected the voyage to Tonga will take five days, and the ship will serve as a base for relief work.

The extent of the devastation wrought by the eruption of an underground volcano and subsequent tsunami on the Pacific nation is yet to be fully realised with communication systems down.

Prime Minister Scott Morrison managed to speak with his counterpart Siaosi Sovaleni on Wednesday afternoon and said Australia's priority remained delivering assistance in a COVID-free manner.

"I reassured him that Australia stands shoulder to shoulder with the Kingdom of Tonga as it responds to the undersea volcanic eruption and tsunami," Mr Morrison said.

"I conveyed Australia's deep sadness for the loss of life and the damage caused by the disaster, and wished those injured a speedy recovery."

Australia and New Zealand have sent flights to survey the damage, revealing knocked over shipping containers at Tonga's Nuku port and volcanic ash covering houses and the runway at Ha'apai airport.

Tonga has also approved the arrival of HMNZS Wellington and HMNZS Aotearoa which departed New Zealand on Tuesday and are expected to arrive on Friday.

Mr Morrison said the Australian High Commission in Nuku'alofa is in close contact with the Tongan government "to ensure our relief efforts best meet the country's immediate needs".

"The government is also engaged with the many Tongans living in Australia to provide information and support," he said.

Power has been restored but communication in and out of the country remains difficult after a key underwater cable was damaged.

New Zealand's foreign ministry says US cable company SubCom advises it will take up to a month to repair the damaged cable.

Telstra is working with Digicel Pacific to find a satellite communications solution while the Australian mission will also help repair the damaged underwater telecommunication cables and set up a temporary satellite system.

The public are set to find out the full reasons why a three-judge panel of the Federal Court ruled unanimously against Novak Djokovic in his bid to have his visa reinstated.

Chief Justice James Allsop will publish the full bench's reasons for its decision at 4.15pm on Thursday.

Djokovic had been set to launch the defence of his Australian Open title in the competition's opening round on Monday, but was instead deported to Serbia.

The 34-year-old may also face a three-year ban on re-entering the country.

He's also been ordered to pay the federal government's legal costs.

Djokovic said in a statement that he was extremely disappointed with the court's decision to dismiss his application but that he respected its ruling.

"I will cooperate with the relevant authorities in relation to my departure from the country," he said.

He vowed to take time to rest and recuperate before making further comments.

The ruling ended an extraordinary saga that had the court sit for five hours on Sunday during its summer holiday, a highly unusual event that reflected the urgency and high stakes of the case.

Djokovic brought the case after his visa was cancelled for a second time on Friday afternoon.

Immigration Minister Alex Hawke cited a risk to public health and the chance that the unvaccinated Djokovic's presence in Australia could excite anti-vaccination sentiment.

Djokovic's visa had earlier been cancelled on the basis that he didn't have an exemption from the requirement to be vaccinated. That decision was revoked and the visa reinstated earlier last week.

Chief Justice Allsop noted the international interest in the case, including in Djokovic's home country, before delivering the ruling on Sunday evening.

He explained that the decision did not involve an appeal against the decision of the Australian government.

Instead it was a judicial review hearing focused on whether the government's decision was irrational or unreasonable in a way that made it unlawful, he explained.

"It is not part of the function of the court to decide upon the merits or wisdom of the decision," Chief Justice Allsop said.

French actor Gaspard Ulliel, known for appearing in Chanel perfume ads as well as film and television roles, has died after a skiing accident in the Alps, according to his agent's office.

Ulliel was 37.

He portrayed the young Hannibal Lecter in 2007's Hannibal Rising and fashion mogul Yves Saint Laurent in the 2014 biopic Saint Laurent.

He is also in the upcoming Marvel series Moon Knight and was the advertising face of the Chanel men's fragrance Bleu de Chanel.

Ulliel was hospitalised on Tuesday after the accident in the Savoie region's Rosiere ski area, the Savoie prosecutor's office said.

The office of the actor's agent said Ulliel died on Wednesday.

It provided no details.

Local broadcaster France Bleu said Ulliel was hospitalised with a skull injury, and that he apparently collided with another skier at a crossing point on the slopes.

The other skier was not hospitalised, according to France Bleu.

Police and prosecutors would not discuss details of the accident.

Ulliel started in television while still in middle school and went on to win two of France's top cinema awards, the Cesar.

Tributes poured in from shocked fans and the corridors of power.

French Prime Minister Jean Castex tweeted an homage that said, "Gaspard Ulliel grew up with cinema and cinema grew up with him. They loved each other madly."

The accident conjured up memories of when Formula One great Michael Schumacher hit his head in a ski accident in 2013 in the French ski resort of Meribel, about 50km from where Ulliel was skiing.

Both were treated at Grenoble University Hospital.

Schumacher, 53, has not been seen in public in eight years, and little has been released about his physical and mental condition.

The German car racing legend suffered serious head injuries when he fell and hit the right side of his head on a rock off the side of a demarcated slope.

He was skiing with his teenage son while on a family holiday in the Alps.

After Ulliel's accident, the mountain police service for the Rosiere ski area said its personnel have been carrying out five or six rescues per day as the snow hardened in recent days.

In the neighbouring Haute-Savoie region, a five-year-old girl was killed on Saturday when a skier crashed into her.

The man was handed preliminary manslaughter charges, according to the Haute-Savoie prosecutor, who cited excessive speed as the likely reason for the accident.

UK Prime Minister Boris Johnson, fighting to save his premiership amid a storm over a series of lockdown parties in Downing Street, has told parliament he will not resign.

Johnson is struggling to quell an internal revolt by his own lawmakers who are angry over the parties in Downing Street, the prime minister's office and residence, during COVID lockdowns, as well as facing opposition calls for him to step down.

Johnson, who in 2019 won his party's biggest majority in more than 30 years on a pledge to "Get Brexit Done," has repeatedly apologised for the parties and said that he was unaware of many of them.

However, he attended what he said he thought was a work event on May 20, 2020 which revellers had been told to "bring their own booze".

"Every week, the prime minister offers absurd and frankly unbelievable defences to the Downing Street parties, and each week it unravels," Keir Starmer, leader of the opposition Labour Party, told parliament.

Starmer, who welcomed the defection of MP Christian Wakeford who left Johnson's Conservatives to join Labour, asked Johnson if a prime minister should resign if he misled parliament.

Asked directly if he would resign, Johnson said: "No".

At the same session, a senior Conservative MP told Johnson he should step down.

"I spent weeks and months defending the prime minister against often angry constituents," former Brexit minister David Davis said.

"But I expect my leaders to shoulder the responsibility for the actions they take," he added, before citing a quote from Conservative lawmaker Leo Amery to then prime minister Neville Chamberlain in 1940.

"I will remind him of a quotation all too familiar to him ... 'in the name of God, go'."

To trigger a leadership challenge, 54 of the 360 Conservative MPs in parliament must write letters of no confidence to the chairman of the party's 1922 Committee.

As many as 20 Conservative MPs who won their seats at the last general election in 2019 plan to submit letters of no confidence in Johnson, the Telegraph reported.

A handful of others have already said they had written such letters.

An analysis by The Times newspaper showed that 58 Conservative lawmakers had openly criticised the prime minister.

Leading rivals within the Conservative Party include Chancellor of the Exchequer Rishi Sunak, 41, and Foreign Secretary Liz Truss, 46.

Johnson on Tuesday denied an accusation by his former adviser that he had lied to parliament about a lockdown party, saying nobody had warned him the "bring your own booze" gathering might contravene COVID-19 rules.

"As he waded through the empty bottles and platters of sandwiches - he didn't realise it was a party? Does the prime minister realise how ridiculous that sounds?" Starmer told parliament.

Downing Street lockdown parties - some held when ordinary people could not bid farewell in person to dying relatives - have undermined Johnson's authority.

Such was the revelry in Downing Street at one event that staff went to a nearby supermarket to buy a suitcase of alcohol, spilled wine on carpets and broke a swing used by the prime minister's young son.

The Mirror said staff had bought a wine fridge for Friday gatherings, events that were regularly observed by Johnson as he walked to his apartment in the building.

Johnson has given a variety of explanations of the parties, ranging from denials that any rules were broken to expressing understanding for the public anger at apparent hypocrisy at the heart of the UK government.

Opponents have called for Johnson to resign, casting him as a charlatan who demanded the British people follow some of the most onerous rules in peacetime history while his staff partied.

"My decision is about much more than your leadership and the disgraceful way you have conducted yourself in recent weeks," said defecting MP Wakeford.

"I can no longer support a government that has shown itself consistently out of touch with the hard working people of Bury South and the country as a whole."

The growing internal Conservative rebellion was cast as the "pork pie plot" because one alleged rebel lawmaker was from Melton, the home of the Melton Mowbray pork pie.

Pork pie is also London slang for a lie.
