Mars' landscape is covered with incredible mountain ranges, sand dunes and ice caps.

Australia's warm start to winter has seen records tumble, but you wouldn't know it depending on where you are, with a stormy "thundersnow" event also hammering our alpine regions this week.

Weatherzone reported that large parts of Australia experienced warmer than usual temperatures for the first fortnight of June, particularly in the central, eastern, and south-eastern parts of the country.

Melbourne has had its sixth warmest start to winter in 169 years of records, with an average minimum temperature of 10 degrees in the past fortnight.

Longreach in Queensland averaged a maximum of 28.6 degrees in that same time – five degrees above average and the town's warmest winter start since 1897.

Adelaide's mean temperature was 16.1 degrees – its second warmest beginning to winter since 1887.

But it's still winter and that has meant snow in Australia's south-eastern mountains, although this time with an unusual companion.

Weatherstone reported a flurry of "thundersnow" earlier this week in the Australian Alps.

A map shows multiple lightning strikes around Thredbo Village near Mount Kosciuszko.

As Weatherzone explains, lightning usually comes with warm air, but it can also strike when it's cold enough to snow.

"With most thunderstorms, you have relatively warm air sitting below cooler air, which creates an unstable atmosphere and causes the warmer air to rise," meteorologist Ben Domensino said.

"In snowy areas, there is generally only a small temperature contrast between the surface and upper levels, so there's usually not enough instability to create the uplift needed for thunderstorm development.

"But when you've got a very cold airmass, there can be enough of a temperature contrast between surface and upper level temperatures to make storms."

Another snowy weather system is expected next week.

A family who settled in Australia eight years ago say they are "upset and frustrated" after being told they must return to the UK – because they are too old.

Glenn and Sheena Tunnicliff swapped England for Perth in 2015.

Glenn, now 57, is a plasterer who has relatives in Western Australia, while 50-year-old Sheena's job as a travel agent manager was in demand and meant she could get the family a visa.

They sold up in East Sussex, near London, and uprooted children, Tamzin, now 21, and Molly, 18, as well as the family Jack Russell Roxy.

They settled in Perth and got jobs, with Sheena going on to open her own travel agency and Glenn working as a plasterer.

They bought a house in Warwick in the city's north.

Their children, who were at school when they moved over, are now also pursuing their own careers: Tamzin is a nurse and Molly is studying Auslan at TAFE.

But visa changes over the years mean the family have never managed to get permanent residency, known as PR, which would have allowed them to stay for good and eventually get Australian citizenship.

It has an age limit of 45, so neither now qualifies.

Now they've run out of options and must go home by August 4.

"We don't want to go back to the UK – we've made a life here," Mrs Tunnicliff said.

"Now we are over that magic figure of 45 there is no route to PR for us.

"Australia classes us as too old.

"We are the ones with the experience and training.

"Australia is turning around saying, 'You're too old but we'll hang on to your kids.'"

Mrs Tunnicliff initially worked as a travel agency manager but now has her own business, a branch of Helloworld.

She employs three people.

Mr Tunnicliff works as a plasterer – an in-demand job on the nation's list of needed skills – and the family is now on his work visa.

But the company which sponsored his visa is about to wind up and there's no other way for the family to get a permanent visa.

Even if he finds a new employer, they're too old to get permanent residency now.

"It's absolutely pointless looking for a sponsor knowing it won't lead to PR," Mrs Tunnicliff said.

She said they have spent more than $80,000 on visas over the years, as well as on advice from visa agents they say has not always been correct.

Daughter Tamzin is able to stay on her own visa as she's now a nurse but faces being separated from the rest of her family.

The family is calling for the rules to change to allow more people who have come to Australia to work to be allowed to stay for good, even if they are over 45.

"We are just a pure working family that have been caught up with all the visa changes over the years," Mrs Tunnicliff said.

"For us to have to leave the country is very frustrating, there has to be something done."

Mr Tunnicliff said much of his family, including his grandparents, moved over as "ten pound Poms" and said it's "disappointing" they're facing having to leave.

"I get why they want to be tough, but I don't understand why someone's not looking at us as a family," he said.

"That's the problem, the moving of the goalposts all the time, and if anything changes with your circumstances you start again.

"We never came here to go home."

Molly, 18, also has to leave, as she won't qualify for a student visa because of the course she is studying.

The family has also been told their dog, Roxy, at 14, might not make the flight due to his age.

Joanne Kinslor, principal solicitor at immigration law specialists Kinslor Prince Lawyers, said the rules are designed for the benefit of Australia – specifically the economy.

"The age limit in place for the vast majority of skilled migrants arises from a policy concern that the working lives and economic contributions of older skilled migrants are likely to be smaller than that of younger migrants," Kinslor said.

"As well as benefiting from the skills and labour of skilled migrants, the Australian community also meets costs in supporting permanent residents of Australia, such as publicly funded healthcare and aged pensions."

However, migration agent Mateja Rautner thinks the 45 age limit is "unreasonable" and said many skilled workers now only have the option of moving to regional areas if they want to stay in Australia.

"The Australian government is actively promoting Australia as the destination for skilled migrants and we are amid global competition for talent and yet we are limiting the options for skilled workers over 45," Rautner told 9news.com.au.

"For this reason, Australia is no longer preferred the destination of choice for many of the world's skilled migrants."

A report in April found the nation's immigration system was broken.

Despite the family's plight, Western Australia, where the family lives, has pledged to cut red tape to get more workers into the state.

The Department of Home Affairs told 9news.com.au they don't comment on individual cases.

A New Zealand league player critically injured during a weekend game is not going to recover, with family and friends now saying their goodbyes.

Papamoa Bulldogs rugby league player Tere Livingston, from the Bay of Plenty, was critically injured on the field on June 10, and suffered a major brain injury from which he will not recover, the club said in a message to members.

"We've received the devastating news that Tere won't recover."

Livingston's partner, Chloe Withrington, said she knew many would want to say their final goodbyes, and would share arrangements soon.

"I am utterly broken, torn in two," she told the community in a heartbreaking message about her partner's injury.

"You were the most generous, warm-hearted person on this earth. The most doting father to our son … I will miss you every minute for the rest of my life."

A fundraiser to support the family with funeral costs has already raised more than NZD$50,000 (A$45,543).

"Tere's partner Chloe and their beautiful 19-month-old baby boy, Nīkora, will be deeply impacted by these circumstances. An amazing man on and off the field, Tere has impacted us all," the Bulldogs club wrote.

"His fun-loving nature is unmatched and the community of people who love him will feel his loss immensely."

Members of the club travelled to Waikato Hospital and will not be playing games this weekend.

A fishing boat carrying migrants trying to reach Europe has capsized and sunk off the coast of Greece, authorities say, leaving at least 79 dead and many more missing in one of the worst disasters of its kind this year.

Coast guard, navy and merchant vessels and aircraft fanned out on Wednesday for a vast search-and-rescue operation set to continue overnight.

It was unclear how many passengers were missing, but some initial reports suggested hundreds of people may have been aboard when the boat went down dozens of kilometres from shore.

Coast Guard spokesman Nikos Alexiou told state ERT TV that it was impossible to accurately estimate the number of passengers.

He said it appeared that the 25- to 30-metre vessel capsized after people abruptly moved to one side.

"The outer deck was full of people, and we presume that the interior (of the vessel) would also have been full," he said.

"It looks as if there was a shift among the people who were crammed on board and it capsized."

Ioannis Zafiropoulos, deputy mayor of the southern port city of Kalamata, where survivors were taken, said that his information indicated there were "more than 500 people" on board.

"It sank very quickly and was gone by the time the rescue helicopter got there," he said.

"The area where this happened has very deep water."

Authorities said 104 people were rescued after the boat sank in international waters some 75 kilometres south-west of Greece's southern Peloponnese peninsula.

The spot is close to the deepest area of the Mediterranean Sea, and the depth could hamper any effort to locate a sunken vessel.

Twenty-five survivors ranging in age from 16 to 49 were hospitalised with hypothermia or fever.

At the port of Kalamata, around 70 exhausted survivors bedded down in sleeping bags and blankets provided by rescuers in a large warehouse, while outside paramedics set up tents for anyone who needed first aid.

Katerina Tsata, head of a Red Cross volunteer group in Kalamata, said the migrants were also given psychological support.

"They suffered a very heavy blow, both physical and mental," she said.

Rescue volunteer Constantinos Vlachonikolos said nearly all the survivors were men.

"They were very worn out. How could they not be?" he said.

Rescuers said many of the people pulled from the water could not swim and were clutching debris. The coast guard said none had life jackets.

The Greek coast guard said 79 bodies have been recovered so far. Survivors included 30 people from Egypt, 10 from Pakistan, 35 from Syria and two Palestinians, the agency said.

The Italy-bound boat was believed to have left the Tobruk area in eastern Libya — a country plunged into chaos following a NATO-backed uprising that toppled and killed longtime autocrat Moammar Gadhafi in 2011.

Human traffickers have benefited from the instability, and made Libya one of the main departure points for people attempting to reach Europe on smuggler's boats.

The route from North Africa to Italy through the central Mediterranean is the deadliest in the world, according to the United Nations migration agency, known as IOM, which has recorded more than 17,000 deaths and disappearances there since 2014.

Smugglers use unseaworthy boats and cram as many migrants as possible inside — sometimes inside locked holds — for journeys that can take days.

They head for Italy, which is directly across the Mediterranean from Libya and Tunisia, and much closer than Greece to the Western European countries that most migrants hope to eventually reach.

In February, at least 94 people died when a wooden boat from Turkey sank off Cutro, in southern Italy, in the worst Mediterranean sinking so far this year.

The Italian coast guard first alerted Greek authorities and the European Union border protection agency, Frontex, about an approaching vessel on Tuesday.

The IOM said initial reports suggested up to 400 people were on board. A network of activists said it received a distress call from a boat in the same area whose passengers said it carried 750 people — but it was not clear if that was the vessel that sank.

After that first alert, Frontex aircraft and two merchant ships spotted the boat heading north at high speed, according to the Greek coast guard, and more aircraft and ships were sent to the area.

But repeated calls to the vessel offering help were declined, the coast guard said in a statement.

"In the afternoon, a merchant vessel approached the ship and provided it with food and supplies, while the (passengers) refused any further assistance," the coast guard said.

A second merchant ship later offered further supplies and assistance, which were turned down, the agency added.

In the evening, a coast guard patrol boat reached the vessel "and confirmed the presence of a large number of migrants on the deck," the statement said.

"But they refused any assistance and said they wanted to continue to Italy," it said.

The coast guard boat accompanied the migrant vessel, which the statement said capsized and sank early on Wednesday (Wednesday afternoon AEST), prompting a massive rescue operation by all the ships in the area.

Alarm Phone, a network of activists that provides a hotline for migrants in trouble, meanwhile, said it was contacted by people on a boat in distress on Tuesday afternoon. That boat was in the same general area as the one that sank, but it was not clear if it was the same vessel.

The organisation notified Greek authorities and Frontex. In one communication with Alarm Phone, migrants reported the vessel was overcrowded and that the captain had abandoned the ship on a small boat, according to the group. They asked for food and water, which were provided by a merchant ship.

"We fear that hundreds of people have drowned," Alarm Phone said in a statement.

The Mediterranean's deadliest shipwreck in living memory occurred on April 18, 2015, when an overcrowded fishing boat collided off Libya with a freighter trying to come to its rescue.

Only 28 people survived. Forensic experts concluded that there were originally 1100 people on board.

Greek President Katerina Sakellaropoulou visited the area where rescued migrants are being tended to, and political parties called off planned campaign events ahead of June 25 national elections.

Former prime minister Kyriakos Mitsotakis, who is widely expected to win easy re-election, said the emergency "dramatically highlights how migration is a problem that requires a cohesive European policy, so that the vile criminal networks that smuggle desperate people at last meet with the decisive response that they deserve".

Separately Wednesday, a yacht with 81 migrants on board was towed to a port on the south coast of Greece's island of Crete after authorities received a distress call.

Independent senator Lidia Thorpe has used parliamentary privilege to accuse Liberal counterpart David Van of sexual assault and harassment, a claim he "utterly rejects".

Van was speaking in the Senate about the handling of Brittany Higgins' rape allegations, when Thorpe began interjecting, calling out "perpetrator" and "you can talk".

As Senate deputy president Andrew McLachlan repeatedly asked Thorpe to stop, the independent senator rose on a point of order.

"I'm feeling really uncomfortable when a perpetrator is speaking about violence," she said.

After being asked by McLachlan to withdraw the "inappropriate" comment, Thorpe continued.

"I can't because this person harassed me, sexually assaulted me and the prime minister had to remove him from his office.

"And to have him talking about this today is an absolute disgrace, on the whole party."

When given the floor again, Van labelled the accusation as "disgusting".

"I utterly reject that statement, that disgusting statement, outright. It is just a lie and I reject it," he said.

"I withdraw the word lie. It is just not true."

Van later released a statement further denying the allegations.

"In the chamber today, Senator Thorpe made unfounded and completely untrue allegations against me that I immediately and unequivocally denied and continue to deny," he said.

"These outrageous and reprehensible comments were made by Senator Thorpe using parliamentary privilege in the most malicious and despicable way.

"My lawyers have written to her already making my position clear in the strongest possible terms."

McLachlan said the matter would be referred to Senate President Sue Lines.

A truck driver has been rescued from inside his semi-trailer after ploughing into a two-storey shopfront in Melbourne's south-east.

It's believed the experienced driver may have suffered a medical episode before slamming into an Engine Australia shopfront on Lonsdale Street in Dandenong about 6.45am.

The man, aged in his 60s, was rushed to The Alfred hospital after suffering non-life threatening injuries.

The store owner Greg Cunningham said it was lucky no one was at work at the time.

"The (truck) has gone through far," he said.

"Since they have built this intersection, it has been a concern for us something like this may happen."

A heavy haulage team was called to the scene to remove the truck from the shopfront.

Cunningham said a massive clean-up was underway, adding the business was set to be closed for weeks.

A former swim coach has been found guilty of 43 child sexual abuse charges relating to 11 different children.

Paul Douglas Frost was convicted on Wednesday afternoon of abusing his former students at a swimming school in Sydney's southwest during the 1990s and 2000s.

The NSW District Court jury had earlier been directed it could deliver majority verdicts before it found him guilty on all counts.

The 43 charges Frost has been convicted of include several charges of sexual intercourse with a child under his authority or care, multiple charges of aggravated indecent assaults of a person under 16 and grooming children for sexual activity.

A juror entered the witness box to tell the court they had not reached unanimous verdicts and were not going to on Wednesday, before the judge said she would take a majority verdict.

"It is preferable that your verdict be unanimous," Judge Sarah Huggett said, before the guilty verdicts returned hours later.

The nine men and three women will be able to request to have their names removed from the jury duty role due to the length of the trial, the judge told jurors as they were discharged, thanking them for giving up months of their time to sit on the case.

Frost and the jury spokesperson were permitted to remain seated while the verdicts were returned due to the length of the indictment.

Frost was handcuffed and taken into custody following the jury's discharge and will face a sentencing hearing in August.

A previous trial had its jury discharged without a verdict after 16 days amid allegations of bullying and refusal to deliberate that a judge worried would taint the outcome.

Frost was once a finalist on cooking competition show MasterChef and his father coached Olympic champion Ian Thorpe.
