News in 5: First Las Vegas victim named; Helen Mirren on the catwalk; New thunderstorm asthma system.

1. What we know about the Las Vegas gunman who killed 58 people overnight.

At least 58 people have died and more than 500 are injured after a lone gunman opened fire upon a Las Vegas music festival on Sunday night.

A 64-year-old man armed with more than 10 rifles rained down gunfire from a 32nd-floor window at the Mandalay Bay hotel. He was firing into a crowd of 22,000 at a Las Vegas country music festival.

On Monday, police identified the gunman as Stephen Paddock, who lived in a retirement community in Mesquite, Nevada – about 145km northeast of Las Vegas. He had no police record or history of violence and reportedly killed himself as police stormed his hotel room.

His girlfriend Marilou Danley is reportedly an Australia citizen and was named a person of interest following the attack.

Danley lived with Paddock in Nevada and multiple news outlets in Australia have reported she was a resident of the Gold Coast until she moved to the US about 20 years ago.

After sending out a request for Danley’s whereabouts, the Las Vegas Metropolitan Police Department said in a subsequent statement late on Monday that “detectives have made contact with her and do not believe she is involved with the shooting on the strip.”​

It’s believed Danley was in the Philippines at the time of the shooting.

Then, in an update on Tuesday morning, Las Vegas Metropolitan Police Department Sheriff Joe Lombardo said Danley was still a “person of interest”. She is due to be interviewed when she returns to the US.

The first victim of the attack to be identified is Tennessee nurse Sonny Melton. Speaking to Fox News, Melton’s wife Heather said he died trying to save her.

“At this point, I’m in complete disbelief and despair. I don’t know what to say. Sonny was the most kind-hearted, loving man I have ever met. He saved my life and lost his,” Heather said.

Heather’s story is one shared by many survivors of last night’s attack, with reports of several brave citizens preparing to sacrifice their lives for the lives of others.

One man, Mike McGarry from Philadelphia, laid on top of students at the concert to shield them from gunfire. “They’re 20, I am 50,” he told Reuters after the fact. “I lived a good life.”

A 29-year-old woman Lindsay Padgett fled the scene after the gunfire started, only to return immediately with her pickup truck to help transport victims to the hospital, ABC News reports.

Australian man Brian Hodge says he was staying in room 32134 of the Mandalay Bay Hotel and gunman Stephen Paddock was in room 32135 as he fired at people at the outdoor country music festival.

"It was a machine gun from the room next to me," Hodge told News Corp Australia, AAP reports. "My floor is a crime scene. They killed a security guard on my floor."

A NSW family was also caught up in the tragedy. Kevin Comerford, Nicole Shipman and her daughter Maddy Aspinall, 14, from Grafton in NSW, were in Las Vegas for one night only - a night that turned into the "scariest night of our lives".

"This was supposed to be a one night special stop because we'd never been to Las Vegas before ... we were planning to live it up for one night and we've had probably the scariest night of our life," Mr Comerford told AAP on the phone.

Mr Comerford said Maddy had coped well with the ordeal.

"That is until we got to the hotel and the police had to walk us through the empty casino with our hands above our head and it became very, very real for her then," he said.

People unable to make contact with loved ones should phone the DFAT emergency hotline: 1300 555 135, or +61 2 6261 3305.

2. Seeing Helen Mirren and Jane Fonda on a Paris catwalk is just what you need this morning.

In a spectacular feat of role-reversal, actresses Dame Helen Mirren and Jane Fonda have dazzled guests on a Paris catwalk, as supermodels such as Naomi Campbell looked on from the front row.

The actresses were modelling for L'Oreal, as the cosmetics giant transformed the Champs-Elysees avenue into a beautiful open-air fashion runway for a one-off event on Sunday.

Other sought-after Hollywood actresses flew in to the French capital to see the collection marking a new chapter of a storied fashion house.

Designer Clare Waight Keller's debut show for Givenchy was one of the hottest tickets at this month's Paris Fashion Week. Cate Blanchett, Rooney Mara and Julianne Moore were in the audience.

3. A Thunderstorm asthma warning system will help save lives in Victoria.

A Victorian nurse fighting to save lives during a freak thunderstorm asthma event as she struggled with her own symptoms has backed the state government's new early warning system.

The new monitoring and alert system will warn people about the risk of thunderstorm asthma events up to three days beforehand following the deaths of nine people in 2016.

Nurse Chantelle D'Souza, who was working in the Footscray emergency department during the storm in November, told reporters on Sunday it was a "very surreal" experience.

"It was very surreal and frightening to say the least," Ms D'Souza said, adding that she carried on working despite struggling to breathe herself.

The new forecasting system will help authorities and the public better predict and understand the phenomenon, Health Minister Jill Hennessy said.

"The great challenge with thunderstorm asthma and epidemic thunderstorm asthma was its scale, its severity, and the fact that we did not have a prediction system in place which would enable us to understand what was coming," she said.

As well as the nine fatalities, thousands suffered respiratory symptoms on November 21 as a result of what experts have described as the world's worst recorded asthma thunderstorm.

The storm kicked up dust and pollen, while the moisture in the air from the humid, hot day burst the pollen into hundreds of tiny allergenic fragments, penetrating deep into victims' airways.

The new emergency system will predict the risk of thunderstorm asthma by analysing grass pollen forecasts, weather observations and data such as temperature, wind changes, rainfall and grass coverage.

4. We need to keep trying with North Korea, says Julie Bishop.

Foreign Minister Julie Bishop insists the diplomatic efforts to rein in North Korea's nuclear weapons program should continue despite Donald Trump's suggestion negotiations are a waste of time.

"I told Rex Tillerson, our wonderful Secretary of State, that he is wasting his time trying to negotiate with Little Rocket Man," the US president tweeted a day after it emerged the US was talking directly with North Korea via diplomatic back channels.

"Save your energy Rex, we'll do what has to be done!"

Ms Bishop believes President Trump was referring to the fact that North Korea has failed to live up to any of the agreements that have been negotiated in the past.

"However, that doesn't mean that we should stop trying," she told reporters in Perth on Monday.

"I believe we must continue to find the political and diplomatic and economic means to pressure North Korea to bring it back to the negotiating table."

Ms Bishop praised Mr Trump's pressure on China, saying it has resulted in Beijing playing an active role in implementing the economic sanctions.

5. Kendall Jenner responds to the criticism she faced after appearing in Pepsi commercial.

It’s been almost six months since Kendall Jenner appeared in the ill-fated Pepsi commercial that sparked astonishing backlash when it appeared to trivialise the Black Lives Matter movement.

The advertisement showed Jenner "bridging the gap" between protestors fighting for love and equality, and the police officers holding them back. When she handed a police officer a bottle of Pepsi, Jenner smiled as the protesters grew quiet and the scene turned into a party.

Cue: backlash due to poor taste and Pepsi pulling the ad almost immediately after its release.

Now, for the first time, the world has been able to see how the controversy affected the 21-year-old first hand, on the season 14 premiere of Keeping Up With The Kardashians.

"I just feel really, really bad. I feel really bad that anyone was ever offended. I feel really bad that this was taken such a wrong way," Kendall tells her sisters. "I genuinely feel like sh*t."

6. The United Nation's refugee arm urges Australia to rethink treatment of those on Manus Island.

The United Nation's refugee arm has urged Australia to lift its game and ensure there's proper care for people detained in Papua New Guinea following the suicide of a Sri Lankan Tamil.

The 32-year-old's death on Monday morning was the sixth refugee fatality on Manus Island in four years.

Australia's immigration department confirmed the death at Lorengau Hospital but directed inquiries to PNG authorities.

Refugees and asylum seekers on the island held a memorial service for the man on Monday afternoon and it's believed his family in Sri Lanka have been notified.

Refugee Action Coalition spokesman Ian Rintoul confirmed the man had been facing rape charges against a local woman following an alleged incident at a motel last year.

The matter was yet to go to court and the man had intended to vigorously defend the charges, Mr Rintoul said.
