Victoria will scrap almost all remaining COVID-19 public health restrictions from midnight as it races towards 90 per cent double-dosed vaccination.

From Friday, fully vaccinated Victorians will be able to dance in clubs, there will be no home visitor limits and no density limits for cafes and restaurants.

"Because 90 per cent of Victorians have gone and gotten vaccinated, so many of these rules, almost all of them can fall away," Premier Daniel Andrews told reporters on Thursday.

Masks will remain for a few more weeks in retail, for hospitality workers, on public transport and for primary school staff, visitors and students in years three to six.

Victoria is expected to hit 90 per cent double-dosed vaccination for the population aged 12 and over this weekend.

It comes as the state recorded 1007 new COVID-19 cases and 12 deaths on Thursday.

The state is now managing 13,814 active coronavirus infections.

It is the first time in five days that the state's daily tally has risen above 1000 cases.

There are 337 virus patients in hospital, with 63 actively infected with COVID-19 in ICU, 65 have been cleared, and 34 on ventilators.

The seven-day hospital average now sits at 384.

Health officials say virus testers processed 72,270 results on Wednesday and 6315 people were vaccinated at state-run hubs.

Victoria is now 88 per cent double-vaccinated in those aged over 12.

Victorians will be allowed back on dancefloors as almost all remaining COVID-19 restrictions are scrapped from midnight, in the state's race towards 90 per cent full vaccination.

From Friday, fully vaccinated Victorians will be able to dance in clubs, there will be no home visitor limits and no density limits for cafes and restaurants.

"You will be able to go back to normal," Premier Daniel Andrews told reporters on Thursday.

"Victoria, like nowhere else in the country, has earned these freedoms."

Non-essential retail will join the state's vaccinated economy, meaning only fully vaccinated people can visit shops unless they are aged under 12 years and two months or have a valid exemption.

Masks will no longer be required for customers visiting hospitality venues, however workers must continue wearing them.

However, Victorians will need to continue wearing masks for a few more weeks in retail settings, on public transport and for primary school staff, visitors and students in years three to six.

From December 15 retail customers will no longer need to wear masks, unless there is a significant jump in hospitalisations.

Indoor events can host up to 30,000 punters, however one-off approval is needed to exceed that capacity.

Events held outdoors can exceed 30,000 attendees if they publish their COVIDSafe plans.

The changes mean the Boxing Day Test and Australian Open will be able to proceed at full capacity, subject to approval of the MCG and Melbourne Park's plans.

People who attend weddings, funerals and places of worship that do not check vaccination statuses will be required to wear masks and be subject to density limits.

There will also be changes to isolation rules, with anyone who comes in contact with a confirmed virus case outside their home not required to self-quarantine.

Close contacts must, however, get a PCR test and isolate until they receive a negative result.

The quarantine change means businesses will no longer have to deep clean their premises after a positive case, or ask the department of health for approval.

Victoria is now 88 per cent double-vaccinated in those aged over 12 and is expected to hit 90 per cent this weekend.

It comes as the state recorded 1007 new COVID-19 cases and 12 deaths on Thursday, the first time in five days the state's daily tally has risen above 1000 cases.

There are 337 virus patients in hospital, with 63 actively infected with COVID-19 in ICU, 65 have been cleared, and 34 on ventilators.

The Duchess of Sussex has said she and her husband Prince Harry are "happy" in California as she spoke about daughter Lilibet's teething troubles in a television interview with Ellen DeGeneres.

Meghan is appearing on The Ellen Show eight months after her controversial sit-down with Oprah Winfrey which left the royal family in crisis.

DeGeneres, a friend of the couple who lives near them in the celebrity enclave of Montecito, asked what Harry loves about California.

"We're just happy," the duchess replied.

Of the Sussexes' five-month-old daughter, DeGeneres said: "Lili's now teething," at which Meghan put her hands to her mouth, saying, "Anything to relieve that".

The talk show host quipped, "Tequila, anything", People magazine reported.

Meghan replied: "That's Auntie Ellen for you".

DeGeneres has previously described the Sussexes as "the cutest couple, so down to earth" and defended them when they faced criticism after taking a series of flights on a private jet.

Eighth in line to the throne Lilibet, who the couple have so far not released public pictures of, was born in the US in June.

She was named after the family nickname used for the Queen, but has yet to meet her great-grandmother, grandfather the Prince of Wales, or Harry's brother Prince William and his wife Kate in person.

In the trailer for The Ellen Show, the duchess, in a white blouse with cut-away detail on the sleeves, chatted about how she used to drive to the same Warner Brothers site for auditions.

"To drive in today was very different," she said.

Meghan said she drove a "very, very old" Ford Explorer and the key stopped working in the driver's side door.

"I would open the trunk and climb in and then pull it shut behind me and crawl over all my seats to get out, that's how I would come to and fro," she said.

Police investigating the disappearance of toddler William Tyrrell have charged his former foster parents with the unrelated assault of a different child.

Strike Force Rosann was established in 2014 after three-year-old William disappeared from his foster grandmother's home at Kendall on the NSW mid north coast.

Earlier this week police returned to the property and nearby bushland, searching for remains as they honed in on a person of interest.

While the search continued for a third day on Wednesday, police delivered court attendance notices to the boy's former foster parents.

NSW Police allege they assaulted a different child at a home on Sydney's upper north shore.

Homicide squad detectives received information about the alleged, unrelated assault as part of the task force's ongoing investigations.

The 56-year-old woman and a 54-year-old man have both been charged with common assault and are due to face Hornsby Local Court on Tuesday.

As the search for William continued, NSW Premier Dominic Perrottet hoped for a breakthrough.

The signs and reporting coming from the police investigation were "very encouraging" and police were doing a "phenomenal" job, the premier said.

"I can speak on behalf of everyone across our state who has been heartbroken by this entire story that we (hope to) have a breakthrough as soon as possible," he said.

Mr Perrottet made his comments after police revealed they had seized a car linked to the case as part of their investigation.

The grey Mazda was seized at a home in Gymea, in Sydney's south, under a coronial order last week. The vehicle is undergoing extensive forensic examination, which could take weeks.

It reportedly belonged to William's foster grandmother before she died.

Police on Wednesday turned their attention to an area of bushland about a kilometre from the house where William was last seen, after digging up patches of garden at the home on Tuesday.

Officers used an excavator to remove a layer of topsoil.

There was a moment of excitement when an item was found on Wednesday afternoon, but it turned out to be nothing.

Rural Fire Service volunteers have been helping to clear bushland and vegetation at the site, and Australian Federal Police officers were present with ground-penetrating radar and 3D cameras.

NSW Police Deputy Commissioner Malcolm Lanyon said investigators were committed.

"Police will not stop until such time as we've investigated every possible lead," he told reporters.

Asked if police were investigating whether William died after falling from a balcony at the house, Police Minister David Elliott said every option was being considered.

"With a mysterious incident like this, every single option has to be investigated, every scenario has to be reviewed and tested," he said.

"Let's hope whatever the conclusion is, (it) gives closure to the families and community."

Police Commissioner Mick Fuller has confirmed there has been a significant breakthrough in the case, saying he was confident police would solve the mystery of what happened to William.

"There is certainly one person in particular that we are looking closely at," he said.

The findings of a coronial inquest into William's disappearance, which concluded last year, are yet to be handed down.

A $1 million reward for information on the case still stands.
