NSW Premier Chris Minns says the discovery of the suspected remains of missing grandfather Chris Baghsarian is "an incredibly tragic development".

Police said a car forensically linked to the 85-year-old was seen a day after his kidnapping near where his suspected remains were found this morning.

"While formal identification is still under way, this is an incredibly tragic development, and our thoughts are with the friends and family of Mr Baghsarian at this heartbreaking time," Minns said.

"This kind of brutality has no place in our community. Police will not stop until they capture those responsible and bring them before the courts. The full weight of the law must come down on these people."

The human remains were discovered near a golf club in Pitt Town in the city's north-west about 8am today during the search for the 85-year-old.

Police are awaiting testing to positively identify the remains as Baghsarian, who was kidnapped from his home in North Ryde about 5am on Friday, February 13.

WEATHER: State warned to brace for thunderstorms and flash flooding

A grey Toyota Corolla forensically linked to an abandoned stronghold in Dural was spotted in Pitt Town about 9pm on February 14, police said.

The car, which had cloned plates but is believed to have been stolen from Victoria, was found burnt out on Good Street in Westmead on February 16.

Detective Acting Superintendent Andrew Mark said information regarding the investigation led police to the golf course.

"We've traced that vehicle that we suspect was involved and that can forensically link the vehicle to Mr Baghsarian, and to the stronghold that we have spoken about in Dural," Marks said.

"Putting that together is why we believe it's Mr Baghsarian."

An autopsy will be conducted.

Baghsarian's family are "deeply upset" by today's discovery and have asked for privacy.

Police will now focus efforts on identifying the offenders.

"The efforts that have gone in, and the response that has come from the public, we're all outraged that this has happened to an innocent man," Marks said.

"I am proud of the police and the efforts. Police have been working 24 hours a day since Friday the 13th."

Marks said he is confident investigators will use every resource available to bring the perpetrators to justice.

Today's search for Baghsarian

9News understands the remains were wrapped up in what appeared to be a carpet or towel.

Police searched dense bushland near Glenorie, about 15 minutes further east, yesterday.

Shortly before 9am today, a number of police vehicles left that search base to travel to a patch of overgrown grassland near Pitt Town Bottoms Road.

Once they arrived at the location, a blue tent – signifying the location of the remains – was raised in minutes.

The overgrown piece of land is located in semi-rural surroundings, with businesses including turf farms nearby.

Police on the scene this morning included tactical, general duties, and forensics officers as well as investigators.

The area has been carefully combed, with officers conducting line searches around where the remains were found.

The update came days after police confirmed they had found a burnt-out car in Sydney's west that has been linked to Baghsarian's abduction.

The car, a grey 2022 Toyota Corolla with cloned plates, was found in Westmead and linked to a crime scene police had established in Dural in Sydney's far north-west.

Police believe those who kidnapped Baghsarian may have taken the grandfather to the property after the abduction.

During a raid, officers seized evidence, including disturbing images of the missing grandfather with his alleged kidnappers.

Videos of Baghsarian have also been sent to police.

The Corolla, which had been spotted near the Dural property, was dumped and burned last Monday after 11.30pm, police said.

It had cloned plates of DVT007, and the Victorian registration 1UZ2BU.

Police have said the person they believe to have been the intended target of the kidnapping is safe and in no immediate danger.

The investigation continues, and anybody who has spotted any suspicious activity around Dural, or who has information or footage showing the car in question, is urged to contact Crime Stoppers on 1800 333 000 or online.

Prime Minister Anthony Albanese has written to his British counterpart backing any plan to remove former prince Andrew Mountbatten-Windsor from the line of royal succession.

His letter has sparked calls for Australia to go further and become a republic instead in the wake of the Mountbatten-Windsor's Thursday arrest on suspicion of misconduct in public office

The UK government has confirmed it was looking at ways to remove him from the line for the throne.

Mountbatten-Windsor is eighth in the line of succession and could technically be named regent or temporarily take over the King's duties even earlier, although Buckingham Palace has effectively ruled that out.

In a letter released last night, Albanese wrote to UK Prime Minister Keir Starmer expressing his support for removing the former Duke of York.

"In light of recent events concerning Andrew Mountbatten-Windsor, I am writing to confirm that my Government would agree to any proposal to remove him from the line of royal succession," Albanese wrote.

"I agree with His Majesty that the law must now take its full course and there must be a full, fair and proper investigation.

"These are grave allegations and Australians take them seriously."

The support of Albanese and the leaders of the other Commonwealth countries who retain the UK's reigning monarch as their head of state is essential to any plan to remove him.

Greens deputy leader and spokesperson for the republic Senator Mehreen Faruqi said the prime minister's letter was not a show of leadership but rather a "humiliating reminder" that Australia is shackled to a "corrupt and crumbling" royal family.

"Rather than pleading with a foreign government to clean up its messes, Australia should be cutting ties altogether and choosing its own head of state," she said.

"Australia needs to confront the bigger truth that the monarchy is an outdated, unaccountable institution built on colonial violence and stolen wealth.

"The latest horrific scandal is not an aberration. It is a symptom of a broken system that is not fit to represent us.

"You cannot polish a rotten crown. The time for a republic is now."

Pro-republic advocates also called to separate from the monarch shortly after the former prince's arrest, saying the head of state should represent the "very best of us".

Mountbatten-Windsor's arrest followed years of allegations over his links with convicted paedophile Jeffrey Epstein, who died by suicide in a New York jail in 2019, but the accusation at the heart was that the royal shared confidential trade information with the disgraced financier when he was a trade envoy for the UK. 

He was released on Thursday night (early Friday AEDT) after spending about 11 hours in custody.

He remained under investigation, meaning he was neither charged nor exonerated.

Emails released last month by the US Department of Justice appeared to show him sharing reports of official visits to Hong Kong, Vietnam and Singapore, and sending Epstein a confidential brief on investment opportunities in Afghanistan.

He has consistently denied any wrongdoing in his association with Epstein but has not commented on the most recent allegations that have emerged with the release of the Epstein files.

In the wake of the arrest, UK Defence Minister Luke Pollard told the BBC that wiping his chances of being a successor to the throne was the "right thing to do" regardless of the outcome.

He told BBC radio at the weekend that the UK government had been working alongside Buckingham Palace to stop Mountbatten-Windsor from "potentially being a heartbeat away from the throne".

UK media quoted unnamed royal sources saying Buckingham Palace would not oppose the move.

While King Charles was able to strip his brother of all his royal and military titles and banish him from Royal Lodge, removing him from the line of succession would require legislation in the UK and the other Commonwealth "realms", including Australia.

In November, University College London said if the worst were to happen to King Charles and then Prince William, Prince Harry would be next in line to be named as regent to Prince George, but only if he returned to the UK.

Were he to refuse, Mountbatten-Windsor would be next in line, although he was "unlikely to be considered suitable following his fall from grace".

"A person can only be removed as a counsellor of state by legislation," it said in an FAQ.

"Because seven people can now be called upon to act as counsellors of state, Andrew Mountbatten-Windsor is very unlikely to be called upon again."

The parents of missing South Australian four-year-old Gus Lamont have issued a plea for information about the disappearance of their son, releasing a new photo and video of him.

Gus Lamont went missing from his Oak Valley Station home in the state's outback on September 27 last year.

His parents, Josh and Jess, have today urged anyone with information about his disappearance to come forward, sharing their grief and devastation.

"Our lives have been shattered, and every moment without him is unbearable," they said in a statement shared by South Australia Police.

"We are united in our search for answers about what happened to our little boy, Gus, who means everything to us… we know someone out there may have information. If someone knows what happened, we are pleading with that person—or anyone who may have seen or heard anything—to please come forward.

"Even the smallest detail could give us the answers we so desperately need."

The new photo released of Gus shows the four-year-old in the back of the car next to a cattle dog.

He is wearing a navy shirt with a graphic design on the front, and long navy pants.

A 10-second video shows Gus riding on a child's bicycle somewhere on the property.

Earlier this month, SA Police declared Gus' disappearance as a major crime.

Police also said a person with close ties to the household, who is not one of Gus' parents, had been speaking to detectives but allegedly "withdrew cooperation." They are now considered a suspect.

Separately, police charged Gus' 75-year-old grandparent Josie Murray with firearms offences, but have clarified those charges are not linked to the toddler's disappearance.

Murray was bailed to appear in the Peterborough Magistrates Court on May 6.

Police say forged medical files and fraud netted Flint more than $180,000.

Employee shareholders at an Aussie start-up are set for a big pay day after the company was acquired for $1.6 billion.

The seven-year-old Australian business owns online weight loss services Juniper and Pilot, which prescribe GLP-1 medication similar to Ozempic and Mounjaro.

Eucalyptus also runs other telehealth services including a fertility program.

The sale will lead to one of the biggest staff share pay-outs in Australian corporate history and give early-stage backers a big pay day.

The Australian Financial Review has reported the value of the shares under the deal, excluding its co-founders, was about $300 million.

The average employee participant is expected to pocket $420,000, with more than 100 to benefit from the sale.

The AFR reported former Eucalyptus chief commercial officer Joe Harris made more than $1 million from the sale.

Eucalyptus chief executive and co-founder Tim Doyle is in line for $163 million by 2029 if he hits several targets.

Early investors including Blackbird Ventures, Who Gives a Crap toilet paper founder Simon Griffiths and Co Ventures founder Maxine Minter will also benefit from the acquisition.

Doyle described the acquisition as a "full circle moment" for the start-up.

"When we were launching Eucalyptus, we drew inspiration from Hims & Hers," he said.

"Hims & Hers is the best-positioned business in the world to be the home for consumer health.

"This is also a moment to look backward and say thank you – to our investors, staff, clinicians, partners and our patients."
