Two families have been left traumatised after their children were mixed up at a Sydney childcare centre, with one baby sent home with the wrong family for hours.

On Monday, a mother went to collect her child from First Steps learning centre in Bangor only to be told that her one-year-old had "already been taken" by a man hours earlier.

After reviewing security footage, it was discovered that a grandfather of another baby was given the wrong child.

He didn't realise and was equally disturbed by the mishap.

Former First Steps employee Annabelle Murray told 9News the incident "was catastrophic and could have been so much worse".

"That's what scares the life out of me, is you had no idea who that man was," Murray said.

"He could have been anybody. It's just so lucky that he brought the baby back," she continued.

Parents and former employees are all furious over the enormous lapse in protocol.

"You just ring the doorbell and you're let in," said a mother.

"Their policy says they need to ask who's at the door, what your name is, and who you're picking up, and they never did that," she continued.

First Steps learning centre has apologised in a letter to parent and has promised to strengthen their drop-off and pick-up protocols.

The letter also reveals the educator involved in the mix-up has been stood down following the incident.

"This Educator has been provided thorough induction training and is aware of the policies and processes regarding drop off and pick up. We have made the decision not to allow her back to the Bangor Service," the letter reads.

"We are working closely with Department of Education, Office of the Children's Guardian and NSW Police, to investigate this incident and to consider whether there is the option to engage in further rehabilitation training. However, we can assure you this will not be at the Bangor Service."

The 56-year-old cybersecurity expert disappeared from his home in Kelvin Grove on August 20 and hasn't contacted family since.

Police charged two men with his torture and scoured multiple crime scenes including a property in Bli Bli on the Sunshine Coast last week.

Anthony Perrett, 38, and Billy Howard, 26, have been remanded in custody, charged with torture.

Text messages tendered as evidence in court last week allegedly include photos of Burow being assaulted.

Detectives this week released vision of three "vehicles of interest".

The cars were a black 2010 BMW X3 with Queensland registration 802NX4, a black 2011 Ford Ranger utility with false Queensland registration 257LX8 and a silver 2007 Mitsubishi Outlander wagon with Queensland registration 385KU2.

The car narrowly misses several kids on their way to school.

Accused gunman Dezi Freeman's wife Amalia was at their Porepunkah property when two police officers were fatally shot, police have confirmed on the ninth day of the manhunt for Freeman.

Crime Command Detective Superintendent Jason Kelly said Amalia was present at the semi-rural property on August 27 and may also face charges "in due course" for obstructing police, when he addressed media today.

Amalia previously called for her husband to turn himself in and has spoke with police.

"She has been interviewed by Victoria Police for obstructing police at the time of the incident the crime that occurred, and a brief of evidence will be compiled, and she may be charged in due course," Kelly said this afternoon.

Amalia described her "deep sorrow" on Sunday in a statement to media over the deaths of officers Neal Thompson, 59, and Vadim de Waart-Hottart, 35, on August 27.

"We are truly sorry for your loss, and the suffering and grief that the families, friends and colleagues are now experiencing. My children and I grieve for the loss of your loved ones," she said in a statement.

Police again today appealed directly to Freeman to surrender.

The accused cop killer remains on the run and there has been no official sighting of him since he allegedly gunned down

Victoria Police Chief Commissioner Mike Bush appealed to Freeman to hand himself in while speaking to media.

"I do appeal to the person responsible to hand themselves in immediately and my message to him is that your destiny is in your hands," Bush said.

Hundreds of police officers with specialist support have been deployed in Victoria's Hume region in the state's north-east as the search for Freeman continues.

Bush said over 100 properties have been searched and hundreds of pieces of information have been collected so far, including from associates of Freeman.

"Victoria Police is very much open to receiving further information that will lead to a safe arrest and that safe arrest can occur if the person responsible for these crimes hands himself in," Bush added.

"And we're still very much open to that possibility and that can be arranged."

The state's fugitive squad forms part of the huge police operation into finding and apprehending Freeman.

"History suggests that we will find the person responsible and we will locate them and put them before the courts," Bush added.

Police are still operating on the theory Freeman is being helped by a member of the public, Bush said.

"That, too, is a real possibility, and we're alive to that possibility and we plan for that possibility. And that's why we appeal not just to him, but to all of his associates," Bush said.

"He does not deserve to be protected."

When asked if police had considered offering a financial reward in the manhunt for Freeman, Bush said it was a possibility.

ADF joins manhunt for Freeman

The Australian Defence Force joined the hunt for Freeman earlier today.

Deputy Prime Minister and Defence Minister Richard Marles said a military planning specialist, as well as aerial surveillance assets, had joined forces with police.

"The Australian Defence Force will work with the Victorian police, as they request our assistance in terms of the particular assets and capabilities that we have, to bring Dezi Freeman to justice," he told ABC.

Police have said they believe Freeman, who is alleged to have shot dead two police officers who were executing a search warrant at his home in Porepunkah, regional Victoria, may be receiving help from members of the public.

The 56-year-old, who has been linked to the so-called "sovereign citizen" movement, has not been seen since the shooting.

Police yesterday swooped on a number of properties in the regional town of Wangaratta, about 75km from Porepunkah.

Superintendent Brett Kahan has called for Freeman to contact triple zero to make a "surrender plan" – along with anybody who has been harbouring or assisting him.

Retired police officer Ian Veitch told 9News police believed the help Freeman was receiving might not be a hiding place, but assistance to help him keep moving around.

World leaders have gathered in Beijing's Tiananmen Square to commemorate the 80th anniversary of World War II.

In front of a 10,000-strong crowd, Chinese leader Xi Jinping praised armed forces and and China was ready to take a leading role in the world.

Following the address, a parade showcased military hardware and featured troops marching in rhythmic lockstep.

Chinese leader Xi Jinping, speaking before a military parade to mark the 80th anniversary of the end of World War II, said humanity today must choose between peace and war and between dialogue and confrontation.

Xi started a brief address by remembering the victims of the war and called for eradication of the roots of war to prevent history from repeating itself.

But Xi's main message was forward looking: today, China is strong, fears no one and is ready to take a leading role in the world.

"The Chinese people are a people that are not afraid of violence and are self-reliant and strong," he said.

At the same time, "We will adhere to the path of peaceful development and work hand in hand with people of all countries to build a community with a shared future for mankind."

The parade began after he spoke with troops marching in rhythmic lockstep, their boots echoing off the pavement, for a review by Xi, who is also head of China's military as chairman of the Central Military Commission.

The parade will showcase missiles, modern fighter jets and other military might as China seeks to wield greater influence on the global stage.

Some of the military hardware is on public view for the first time.

Before they started marching, Xi rode by the entire length of the formations along Beijing's central Chang'an Avenue in a classic-style black limousine.

He stood up through an opening in a roof with four microphones lined in front of him and greeted flanks of troops as he passed them and rows of missiles and military vehicles.

They shouted back mottos in unison such as: "We serve the people."

Before Xi spoke, the ceremony began with an 80-gun artillery salute to mark the 80 years since the end of the war, followed by the national anthem, the March of the Volunteers, a song composed in 1935 during the early years of resistance against invading Japanese forces.

Xi and his invited guests including Russian President Vladimir Putin and North Korean leader Kim Jong-un arrived earlier at the historic Tiananmen Gate to watch the parade.

Xi shook hands individually with guests on a red carpet before they climbed the stairs up to the viewing platform overlooking Tiananmen Square.

Putin and Kim flanked Xi as they made their way to the platform.

They paused to shake hands with five WWII veterans, some older than 100.

As the parade got underway, US President Donald Trump said on social media that the big question is whether Xi will recognise the contributions of Americans who fought in the war.

He added: "Please give my warmest regards to Vladimir Putin, and Kim Jong-un, as you conspire against The United States of America."

Xi, in his remarks, did not mention America by name but expressed his gratitude to foreign countries who helped China resist the Japanese invasion.

Domestically, the commemoration of the anniversary is a way to show how far China has come. China was a major front in the war, a fact often overlooked in accounts that focus more on the fight for Europe and US naval battles in the Pacific.

A Japanese invasion before the war and the conflict itself killed millions of Chinese people.

The military parade is also a show of strength to boost support for the Communist Party and its leader, Xi, domestically, and a way to portray itself as a global alternative to the American-dominated postwar era.

"The Chinese people's rejuvenation cannot be blocked, and the noble goal of the peaceful development of human civilisation must triumph," Xi said at the end of his speech.

The ceremony began with an 80-gun artillery salute to mark the 80 years since the end of the war, followed by the national anthem, the March of the Volunteers, a song composed in 1935 during the early years of resistance against Japanese forces in the country.

A sea of people sat in clearly demarcated sections on the square across the wide avenue as the soldiers marched past.

They waved small red flags as choirs sang patriotic songs including Defend the Yellow River and No New China without the Communist Party of China.

Former Victorian premier Daniel Andrews has been seen shaking hands with Chinese President Xi Jinping prior to the nation's grand military parade.

The parade, which boasts other guests including Russian President Vladimir Putin and North Korean dictator Kim Jong-Un, marks the 80th anniversary of the end of World War II.

Andrews was accompanied by former NSW premier and foreign minister Bob Carr.

The two are reported to be among the 10,000 strong crowd watching the event in Beijing's Tiananmen Square.

The former politicians, who have a record of forging links with China, are attending in a personal capacity.

The parade will showcase China's newest warfighting kit, including hypersonic missiles, tanks, stealth fighters in a display of the communist ruled nation's military arsenal.

Analyst Neil Thomas, from the Asia Society Policy Institute think tank, told Today this morning the parade had drawn a "rogues' gallery" of authoritarian world leaders, including North Korean dictator Kim Jong-Un and Russian President Vladimir Putin.

He said the attendance of Carr and Daniels would likely bolster the Chinese government's efforts to promote the event, and its claims China was the major force behind Japan's defeat in World War II.

"They're (Carr and Daniels) not representing Australia, although, of course, they did hold senior roles in state governments before.

"So it's certainly the case that China is looking to use their participation to bolster the international reach and legitimacy of this parade."

In addition to the North Korean and Russian dictators, the leaders of hardline regimes such as Iran and Belarus will also be watching the parade.

"The fact that the company you have at this parade is a rogues gallery of international leaders like Vladimir Putin and Kim Jong-Un, it certainly doesn't leave a good taste in your mouth," Thomas said.

The federal government confirmed senior Australian officials will not be attending.
