An Australian mother has revealed how she and her young son survived a freak accident on Christmas Day in New York.

The woman and nine-year-old boy were in the US city for a holiday when they were struck by a taxi a block away from the landmark Macy's department store.

Good Samaritans saved the pair who were under the cab after the 58-year-old driver suffered a medical episode and ploughed onto the footpath on Boxing Day (AEDT).

"It hit us from behind, it hit us from behind," the mother, who was not identified, told US media.

"I didn't even know what had happened. I just remember being on the ground and something on top of me.

"I could hear the wheels screeching and my son screaming next to me."

The woman's son suffered a broken leg and has undergone two rounds of surgery.

"He's got severe burns on his leg as well, he's going to be in hospital for quite some time," the mother said.

The mother and son were among six people injured in the incident.

Ryan Tucker, whose wife was struck on the shoulder by the cab, said after he checked his wife was OK, he went to help the young boy.

"He was trapped under the tyre, and when we moved the car back, [we] realised that what ended up being his mum was underneath the car," Tucker told CBS News.

"She was coherent, she was talking to her son, smiling, trying to help keep him calm."

Video shared on social media shows a group of people rocking the taxi back to free the mother and son.

Tucker said the boy, who was hospitalised with an injury to his thigh, told him it was the worst holiday ever.

Two others were also transported to hospitals for their injuries, all in a stable condition, including a 41-year-old woman who reportedly suffered a head injury and a 49-year-old woman who reportedly suffered a leg injury.

Three others, reportedly aged 19, 37 and 49, refused medical attention.

A New York Police Department spokesperson said the 58-year-old taxi driver may have suffered a medical episode, but the investigation had yet to confirm that as the cause.

The taxi jumped the curb near Macy's flagship store at Herald Square about 4pm on Wednesday (8am Thursday AEDT) and hit the pedestrians on the footpath, police said, adding that the driver remained at the scene.

Video footage from the scene showed a damaged yellow taxi on the sidewalk cordoned off by police tape. The car's front bumper appeared to have fallen off.

The taxi was towed away later in the evening.

Aviation experts say an Azerbaijani airliner that crashed in Kazakhstan most likely went down after being hit by Russian air defence systems.

Here are some things to know about the crash that killed 38 out of the 67 people on board.

How did the plane crash?

Azerbaijan Airlines' Embraer 190 was en route from the Azerbaijani capital of Baku to the Russian city of Grozny in the North Caucasus on Wednesday when it was diverted for reasons that aren't yet fully clear.

It crashed while trying to land in Aktau, Kazakhstan, after flying east across the Caspian Sea.

The plane went down near the coast about three kilometres from Aktau.

Mobile phone footage circulating online appeared to show the aircraft making a steep descent before hitting the ground and exploding in a fireball.

Rescuers rushed 29 survivors to hospitals.

How did Azerbaijan react?

Azerbaijan observed a nationwide day of mourning on Thursday.

National flags were at half-mast, traffic across the country stopped at noon, and sirens were sounded from ships and trains.

Speaking at a news conference on Wednesday, Azerbaijani President Ilham Aliyev said that the weather had forced the plane to change from its planned course.

What do officials and experts say about a possible cause?

Kazakhstani, Azerbaijani and Russian authorities say they are investigating the crash.

Embraer told The Associated Press in a statement that the company is "ready to assist all relevant authorities".

Russia's civil aviation authority, Rosaviatsia, said that preliminary information indicated the pilots diverted to Aktau after a bird strike led to an emergency on board.

While officials remained tight-lipped, an Azerbaijani lawmaker directly pointed the finger at Russia.

Rasim Musabekov told the Azerbaijani news agency Turan that the plane was fired upon in the skies over Grozny and urged Russia to offer an official apology.

Some aviation experts say the holes seen in the plane's tail section after the crash indicate that it could have come under fire from Russian air defence systems fending off a Ukrainian drone attack.

Mark Zee of OPSGroup, which monitors the world's airspace and airports for risks, said that the analysis of the fragments of the crashed plane indicate with a 90-99 per cent probability that it was hit by a surface-to-air missile.

Osprey Flight Solutions, an aviation security firm based in the United Kingdom, warned its clients that the "Azerbaijan Airlines flight was likely shot down by a Russian military air-defence system".

Osprey CEO Andrew Nicholson said that the company had issued more than 200 alerts regarding drone attacks and air defence systems in Russia since the full-scale war in Ukraine began in February 2022.

FlightRadar24 said in an online post that the aircraft had faced "strong GPS jamming" that interfered with flight tracking data allowing to monitor planes' flight path.

Russia has extensively used sophisticated jamming equipment to fend off drone attacks.

A day later, no definitive word

Yan Matveyev, an independent Russian military expert, noted that the images of the crashed plane's tail show damage compatible with shrapnel from the Russian Pantsyr-S1 air defence system.

It's unclear why the pilots decided to fly hundreds of kilometres east across the Caspian Sea instead of trying to land in Russia after the plane was hit, he said, adding that they probably faced restrictions on landing at a closer venue and may have thought that the damage was not critical.

In Azerbaijan, Caliber online newspaper also claimed that the airliner was fired upon by a Russian Pantsyr-S air defence system and also had its systems affected by jamming equipment as it was approaching Grozny.

The paper questioned why Russian authorities failed to close the airport despite the drone attack in the area on Wednesday, and why they didn't allow the plane to land in Grozny or other Russian airports nearby after it was hit.

Asked about the claims that the plane had been fired upon by air defence assets, Kremlin spokesman Dmitry Peskov told reporters on Thursday that "it would be wrong to make hypotheses before investigators make their verdict".

Officials in Kazakhstan and Azerbaijan have similarly avoided comment on a possible cause of the crash, saying it will be up to investigators to determine it.

A southerly buster is moving along parts of the NSW coast, bringing relief for heat-affected residents.

The heat which affected South Australia, Victoria and western parts of NSW yesterday swept into Sydney and eastern parts of NSW today.

Greater Sydney and surrounding areas were under a total fire ban as more than 30 bushfires and grassfires were burning this afternoon.

A cool change has since moved into the NSW south coast, including Wollongong, this afternoon.

There is a risk of thunderstorms parts of Sydney, Wollongong and the Hunter before a drop in temperatures, according to the Bureau of Meteorology.

The storm caused some damage around Sydney, including to restaurant Brazilian Flame in Zetland.

"In Sydney, we'll see that cool change push through between 5pm and 6pm," senior Meteorologist Jonathan How said earlier this afternoon.

"In Newcastle and the Hunter, (it will hit) by about 9pm."

"The temperature will drop back quite significantly through the day.

"Thankfully it will be just that one hot day today, with much cooler conditions coming through tonight.

A cool change came through yesterday for Victoria and South Australia, with both states still fighting bushfires.

The two men who died in separate accidents during the Sydney to Hobart yacht race overnight have been identified as experienced sailors.

South Australian man Nick Smith, 65, was on board Bowline and competing in his fifth Sydney to Hobart when he was killed.

While it was previously reported by NSW Police and the Cruising Yacht Club of Australia (CYCA) that Smith had been struck by a boom, it is now believed the crew member struck his head after being hit by the mainsheet.

"I've had the pleasure of racing with Nick previously on other vessels, and he was a great, down-to-earth sailor, a very experienced offshore sailor," Owen Haskett, rear commodore of the Royal South Australian Yacht Quadron, said.

"We extend our condolences to Nick's family, friends and crew at Bowline at this tragic time."

The second sailor has been identified as Western Australian man Roy Quaden, 55.

Quaden was an experienced sailor with more than 20 years on the water under his belt and was the navigator on board the Flying Fish Arctos during the race.

The CYCA confirmed his identity in a statement released this afternoon.

"It is understood he was struck by the yacht's boom during an incident which occurred overnight approximately 30 nautical miles east/south-east of Ulladulla, NSW," the statement read.

"Fellow crew members performed CPR, but they could not revive him."

Police said this morning that the men may have both been struck by a boom while changing sail when they suffered their fatal injuries.

However, this afternoon, the CYCA's vice commodore David Jacobs said he believed Smith was hit by the mainsheet of the yacht.

"We thought that he had been hit by the boom, as had Roy, and we've now learned that that wasn't the case," he said.

"He was hit by the mainsheet, and the mainsheet threw him across the boat, and unfortunately he hit his head on the winch, and that's what killed him."

Just before midnight, the Australian Maritime Safety Authority received a mayday call from Flying Fish Arctos after a 55-year-old male crew member from Western Australia was struck on the back of the head with a boom, NSW Police Superintendent Joe McNulty said.

His fellow crew performed CPR but he was unable to be revived.

At about 2.30am, a second mayday call came from Bowline, where Smith had suffered a similar injury.

He also received CPR, but died.

McNulty said both vessels were now in port and had been seized as evidence, with crime scene investigators on board and police conducting interviews.

Crew members have been offered counselling.

Sailing community shattered

Jacobs said his thoughts were with the families and loved ones of those who died, as well as "the whole of the sailing community".

"It's a very close community," he said.

"Every member of that community, every person in that race, will be feeling this acutely."

Prime Minister Anthony Albanese also issued his condolences.

"We have sadly awoken to tragedy in the Sydney to Hobart with the awful news two sailors have lost their lives," he said.

"Our thoughts are with the crews, their families and loved ones at this deeply sad time."

Jacobs confirmed there would be an investigation into the incident.

"We always want to improve safety wherever we can, so we will do an investigation and if there is something that boats can do to prevent this happening, we will implement it," he said.

He denied that the race should have been cancelled, saying the forecast weather had not been "extreme".

"These fleets can handle those winds easily," he said.

"They are ocean racers, they are used to the winds and they are not extreme conditions."

McNulty confirmed conditions overnight had not been dangerous, but warned of a "challenging night" ahead.

He said police and rescue vessels would be on alert and ready to help as the fleet headed into the Bass Strait.

Man rescued after going overboard

Jacobs said another tragedy had been averted overnight after a crew member of Porco Rosso fell overboard in a "terrifying" incident.

"That person was swept about 1.2 nautical miles from the boat, but all of the safety procedures clicked into place," he said.

"His PLB, his personal location beacon was activated," he said.

"AMSA (Australian Maritime Safety Authority) contacted our race control, AMSA dispatched a plane to search for it.

"Boats were diverted to help find the person and the boat, actually he fell off, was able to retrieve him.

"So it was a good outcome. And he's fine and healthy."

Police identified the man as 37-year-old Luke Williams.

The best places to buy a lottery ticket last year have been revealed.

Exclusive: Two decades have marched by since Joe Giardina lost his 'joyful' and 'loving' son Paul but his memory burns brighter than ever.

Joe, his wife Evanna and their 16-year-old son Paul were on holiday in Phuket, Thailand when the 2004 Boxing Day tsunami struck, killing 227,898 people.

Paul was one of them. He was swept away in the wave while Joe, who tried to save his son, survived a near-drowning in an incredible stroke of luck.

Joe, who lives in Melbourne with his wife Evanna, told 9news.com.au the past 20 years have been tough but he knows Paul managed to fit a lifetime of love in his short time on earth.

"Every parent's nightmare is to lose a child, mine was even worse in the sense that I wasn't able to hold onto him… I lost him," Joe said.

"I felt that I'd let him down. But I also knew there was nothing I could have done, it was outside of my control."

The Giardinas were having breakfast at their hotel in Phuket when the tsunami came.

The force of the water dragged Joe into a stairwell on the third floor of the hotel, while Paul was ripped away from his father.

While Joe avoided drowning and survived with some broken bones, Paul's body was found three days later.

For a long time, this haunted Joe. 

Now 20 years after the tsunami, he said time has healed a lot of those wounds.

"We also have to acknowledge that it's not just us. There's 26 Australians in total, so 25 other Australians that lost their lives, and 230,000 worldwide," he said.

This is why Joe wanted to have a permanent tribute to those who died in the disaster.

He was pivotal in lobbying the Australian government to create a memorial in 2015 in Canberra, which remembers Paul among thousands of others.

Every parent's nightmare is to lose a child, mine was even worse in the sense that I wasn't able to hold onto him… I lost him.

Joe also visited Canberra in November to mark the milestone this Boxing Day.

"It was part of the healing process, not just for me but all the Australian families," Joe said.

"It's difficult to believe that it's been 20 years, it feels like maybe 10 or 12 years, it's still really vivid."

Joe has visited Thailand again too and reclaimed his memories of the beautiful South-East Asian country after the nightmare he endured.

He's also had a long time to think about the word 'survivor' and what it means to have lived, while his son didn't.

"It's a word of joy, because I survived a near-death experience," Joe added.

"I have come to terms with the challenges that life presents, it's reality. 

"I don't feel anger, it's the journey. We would obviously prefer not to have taken this journey, but it's the reality of life."

The years may have flown by but Paul will forever be 16.

Little things spark memories of Paul all the time and Joe loves it when the universe offers him a little reminder of his son.

"He would have been 16, there's sadness in the fact we never got to see that side of Paul," Joe said.

"Paul was just love. In photos of Paul, there's always a smile or cheeky grin on his face. That was Paul, the Paul we knew, we loved and continue to love, we were blessed.

"It was 16 short years, 16 amazing years."

Exclusive: Australian journalist Kimina Lyall worked a demanding job as a South-East Asian correspondent in Thailand and found an escape on the tiny island of Ko Phra Thong, the "Golden Buddha Island".

It was a relatively normal morning for her on December 26, 2004.

The then-38-year-old had filed an article and was at a resort meeting with her partner when a loud sound blasted around them.

"I thought it was a plane crash, a plane had crashed into the water," she told 9news.com.au.

"We ran up to the beach and then there was this really big wave that had come all the way to the top of the beach and then just sort of washed out."

They laughed it off but Lyall's gaze went to the horizon, where another wave was breaking.

"We just all watched it get closer and closer and closer and most people were transfixed," she said.

"There was one person who had lived in Japan and she knew what it was. She was running up and down the beach yelling 'run, run, run, everybody run'."

What was quietly approaching was one of several tsunamis caused by the 9.1 magnitude earthquake that struck off the coast of northern Sumatra, Indonesia.

Lyall's gut instinct took her to the top of a hill.

As she was scrambling up, the tsunami hit the shore and tore through the island, destroying her home.

A total of 94 people on Ko Phra Thong were killed, including about 13 out of about 100 people on Lyall's side of the island.

"For me, the impact was also needing to go and cover the story, the biggest story of my life and I couldn't get off the island because there were no boats," she said.

"It took me a day to get off the island and then a lot of news pressure to go and find stories and file them."

In the end, almost 230,000 people were killed across several countries by the Boxing Day tsunami, which remains the worst natural disaster of its kind in history.

Lyall was eventually called back to Australia but she found it difficult to return.

In Thailand, everyone had a shared understanding of what had happened and had been impacted in some way or another.

But in Australia, people had moved on. 

Lyall's relationship with her partner broke down, she was diagnosed with PTSD and she was forced to quit her job as a journalist. 

"I couldn't cover a story like that again and I didn't want to," she said. 

"I was running around chasing terrorists and world leaders and now I'm at some stupid press conference about a road being built or something so I felt very disillusioned for a long time."

Lyall went back to university and retrained as a psychologist.

"It's the same as journalism, only one is really confidential and the other is really not. But it's just meeting people and learning their stories," she said.

READ MORE: A prisoner woke expecting to be executed. Instead they set him free

She also joined the Dart Centre for Journalism and Trauma as deputy chief executive and worked to train journalists in trauma-safe reporting and support journalists exposed to trauma.

She's been returning to Thailand ever since and spent time there writing her book, Out of the Blue: Facing the Tsunami, detailing her experience.

"It's one of those things where… it's part of your life. It's part of your story," she said.

Ahead of yesterday's 20th anniversary, Lyall didn't think she would be any more affected by it than she would any other day. 

But she was surprised to find the event was very much alive for her.

READ MORE:

"Three or four weeks ago, I just started getting quite upset about it. I really feel like this 20-year one, for some reason, has hit me harder than any of the other ones," she said.

"I'm sort of surprising even me, just really aware of, thinking a lot about the people who died, and not just people I know, but people who I don't know.

"The 230,000 people, they're gone and barely thought about except for their closest people."

Lyall has been able to figure out and adjust to her new life and said she hasn't let the tsunami define her too much.

"Everyone has a tsunami," she said.

"At some point in everyone's life, there's something that's so dramatic, usually traumatic, that's life-changing."

Azerbaijan on Thursday observed a nationwide day of mourning for the victims of the plane crash that killed 38 people and left all 29 survivors injured as speculation mounted about a possible cause of the disaster that remained unknown.

Azerbaijan Airlines' Embraer 190 was en-route from Azerbaijan's capital of Baku to the Russian city of Grozny in the North Caucasus on Wednesday when it was diverted for reasons yet unclear and crashed while making an attempt to land in Aktau in Kazakhstan after flying east across the Caspian Sea.

The plane went down about 3 kilometres from Aktau. Cellphone footage circulating online appeared to show the aircraft making a steep descent before smashing into the ground in a fireball.

Other footage showed part of its fuselage ripped away from the wings and the rest of the aircraft lying upside in the grass.

On Thursday, national flags were lowered across Azerbaijan, traffic across the country stopped at noon, and signals were sounded from ships and trains as the country observed a nationwide moment of silence.

Speaking at a news conference Wednesday, Azerbaijani President Ilham Aliyev said that it was too soon to speculate on the reasons behind the crash, but said that the weather had forced the plane to change from its planned course.

"The information provided to me is that the plane changed its course between Baku and Grozny due to worsening weather conditions and headed to Aktau airport, where it crashed upon landing," he said.

Russia's civil aviation authority, Rosaviatsia, said that preliminary information indicated that the pilots diverted to Aktau after a bird strike led to an emergency on board.

According to Kazakh officials, those aboard the plane included 42 Azerbaijani citizens, 16 Russian nationals, six Kazakhs and three Kyrgyzstan nationals. Russia's Emergencies Ministry on Thursday flew nine Russian survivors to Moscow for treatment.

As the official crash investigation started, theories abounded about a possible cause, with some commentators alleging that holes seen in the plane's tail section possibly indicate that it could have come under fire from Russian air defence systems fending off a Ukrainian drone attack.

Ukrainian drones had previously attacked Grozny, the provincial capital of the Russian republic of Chechnya, and other regions in the country's North Caucasus. Some Russian media claimed that another drone attack on Chechnya happened on Wednesday, although it wasn't officially confirmed.

Osprey Flight Solutions, an aviation security firm based in the United Kingdom, warned its clients that the "Azerbaijan Airlines flight was likely shot down by a Russian military air-defence system."

Osprey provides analysis for carriers still flying into Russia after Western airlines halted their flights during the war.

Osprey CEO Andrew Nicholson said that the company had issued more than 200 alerts regarding drone attacks and air defense systems in Russia during the war.

"This incident is a stark reminder of why we do what we do," Nicholson wrote online.

"It is painful to know that despite our efforts, lives were lost in a way that could have been avoided."

Asked about the claims that the plane had been fired upon by air defence assets, Kremlin spokesman Dmitry Peskov told reporters that "it would be wrong to make hypotheses before investigators make their verdict."

Kazakhstan's parliamentary Speaker Maulen Ashimbayev also warned against rushing to conclusions based on pictures of the plane's fragments, describing the allegations of air defence fire as unfounded and "unethical".

Other officials in Kazakhstan and Azerbaijan have similarly avoided comment on a possible cause of the crash, saying it will be up to investigators to determine it.

Despite the Boxing Day shopping rush, new data shows consumers are grappling with big price hikes in everyday goods and services.

And that's causing a big headache for the federal government.

In the two-and-a half years since the last election a number of items in the shopping trolley have gone up, according to analysis from the Parliamentary Library in Canberra.

READ MORE: DJ charged over out-of-control Fremantle beach party

Data shows eggs have gone up the most – increasing by 28.6 per cent, while a loaf of bread is up by 22.7 per cent.

In the dairy aisle, the price of milk and cheese is up by around 20 per cent.

It's the same story for fresh fruit, which is up by 20.4 per cent, while breakfast cereals are also up 20.2 per cent.

But there's good news for meat eaters, with the price of red meat – both lamb and beef – dropping by six per cent.

However, the hit to the hip pocket isn't just at the supermarket.

We're seeing big price hikes in insurance costs, which are up by 34.1 per cent.

And if you're lucky enough to be thinking about an overseas holiday, you might need to think twice because international travel and accommodation has gone up by a whopping 50.7 per cent.

Petrol prices have also come down, while the price of childcare has remained relatively steady.

The government is trying to intervene by putting pressure on supermarkets to reign in price hikes.

Federal Labor is also dishing out those $300 rebates on electricity, which has seen power bills come down significantly in recent months.

The price rises are impacting the Labor government, who are losing support of a key demographic, those aged between 35-49 year-olds, according to the latest Newspoll analysis.

It shows the age group, who are likely to be paying a mortgage and struggling under continued higher interest rates, moving steadily away from Labor.

Over the last three months, the demographic has moved strongly towards the Coalition.

Those voters potentially blaming the government for cost of living pressures but Labor does say helping people with rising prices is their top priority.

As it gets closer to the next election, NSW is shaping up to be a key battleground state.
