More than 14,000 winter booster doses have been administered since the rollout began this week.

The rollout of the fourth COVID-19 vaccine dose, or second booster, to elderly and vulnerable Australians began on Monday, ahead of a predicted surge in infections during winter.

The head of Australia's vaccine rollout, Lieutenant General John Frewen, told a Senate estimates hearing on Wednesday there had been 14,300 winter booster doses given in just the first two days.

There were 6600 doses administered on Monday, with a further 7700 given out on Tuesday.

However, Lt Gen Frewen told the hearing more people over 65 had already received their fourth dose before the Monday rollout due to being immunocompromised and needing an additional dose in their initial course.

He said more than 100,000 winter doses had been given as a result, with more than 60,000 of those being to people over 65, while there have been 1696 doses given to Indigenous Australians over 50.

The rollout head said more than one in 10 people were overdue for their first booster shot.

Estimates was told more than 11 per cent of the eligible population had yet to receive their third dose of a vaccine.

Lt Gen Frewen said there had been a range of reasons why some people were shunning the booster take-up.

"There is both elements of some confusion and elements of some complacency," he said.

"It comes (down) to people no longer as fearful of Omicron as they were with previous variants. People have had it and have moved on and thought, 'no big deal'."

Latest vaccination figures show more than 94 per cent of those in aged care - and more than 90 per cent of those over 70 - have had their first booster.

Lt Gen Frewen said Australia was ranked 22nd out of OECD countries for the booster rollout.

He told estimates the rate was due to the booster rollout starting later than other countries and nations using different metrics for the rollout.

Australia's OECD ranking for two doses is fifth.

"Originally we were much lower down the OECD rankings for two doses, and as our rollout has proceeded, we've climbed right to the heights," Lt Gen Frewen said.

"We will see that through the booster program as well."

Despite the potential for a surge in COVID cases in winter thanks to new variants, chief medical officer Paul Kelly said Australia was in a good position to handle it.

"While there may be challenges ahead, I see no reason why, even with the easing of restrictions, the strong position in Australia will not likely change over the winter months," he said.

"The 2022 winter season may well present challenges to health systems, healthcare providers, aged care and disability care residents, communities and the economy."

While Professor Kelly said the threat of a new variant was a possibility, Australia would be prepared to handle the situation.

"Work is well under way in all states and territories ... to prepare our healthcare system for the likely co-circulation of COVID-19 and influenza," he said.

"The general principle will be to move away from reducing COVID-19 transmission to protecting people at higher risk of developing severe disease, essentially reducing harm."

A man accused of murdering of a wealthy Gold Coast retiree almost three decades ago has been granted bail amid claims detectives made cash payments to witnesses for statements.

Philip Michael Stearman is charged with murdering 89-year-old Gold Coast inventor Hugo Benscher in June 1992.

The high-profile crime baffled investigators until a cold case breakthrough when Stearman, 64, was arrested in Tasmania and charged with murder in 2020.

The former Gold Coast resident has been in custody since his arrest.

But Supreme Court Justice Peter Callaghan on Wednesday granted Stearman bail following a hearing last month.

Stearman's detention could no longer be justified because of the weakness of the prosecution case, defence barrister Tim Ryan argued during the earlier proceedings.

"The investigation that lead to Mr Stearman's arrest was a relatively superficial one," he said.

The prosecution case is based on alleged admissions made to several friends and associates in the years after Mr Bencher was killed.

The court was told the case relied on admissions by some witnesses with extensive criminal histories and substance abuse issues who were paid by police.

Justice Callaghan described the payments as "extraordinary".

"I certainly have never seen the like," he said earlier.

The Crown did not comment on the "propriety or otherwise" of the cash transactions, but argued the payments were "relatively small".

"You say that, but $200 can be a fortune to people with a substance abuse issue," Justice Callaghan added.

"If the payments were being made on the day a statement was made, it's hard to resist the inference."

A committal hearing in December was told Stearman boasted of "killing a guy on the Gold Coast", discussing it "three or four times" over the years.

But when asked if he believed the story the witness said "not really".

"I thought he was a bit of a bragger ... it wasn't something I was overly concerned about."

Police previously alleged Stearman had been involved in a botched robbery of Mr Benscher's home.

Born in Hamburg in 1903, Mr Benscher emigrated to Australia in 1948, where he made his fortune by inventing the inflatable ball bladder and valve.

After living most of his life in Sydney, he retired to the Gold Coast in 1986 where he lived alone until his death.

The widower's body was found by Mr Benscher's now-deceased former assistant on the kitchen floor of his plush Paradise Point home, tied and gagged with evidence of head injuries.

Footprints found in the canal sand leading to Mr Benscher's home prompted speculation that more than one person was involved.

Detectives found no fingerprint or DNA evidence at the crime scene.

Only a bedroom where Mr Benscher hid cash was disturbed, with a canvas bag, cash and traveller's cheques stolen.

Victoria could drop its COVID-19 vaccine mandates in restaurants, cafes, pubs and nightclubs after the latest wave of infections, expected to peak within weeks.

The state's hospitals are bracing for 500 or more patients a day with the virus at the height of the Omicron BA.2 sub-variant outbreak, according to Health Minister Martin Foley.

However, overall daily case numbers are harder to predict because of factors including the number of people getting tested and those who are asymptomatic.

With cases still rising through April, Victoria will not yet be following Queensland's lead from April 14 by dropping the vaccine mandate for hospitality venues.

But Premier Daniel Andrews indicated that could be revisited once infections start falling again.

"Let's get through these next few weeks, let's get past this peak in sub-variant Omicron cases and then we'll have options," Premier Daniel Andrews told reporters on Wednesday.

"One of those, hopefully, will be dealing with things like the vaccinated economy and all sorts of other rules."

Mr Andrews last year flagged Victoria's vaccinated economy would remain in place until at least this weekend's Formula One Grand Prix and possibly throughout the entirety of 2022.

The state's pandemic declaration, which allows the government to enforce ongoing restrictions as well as mask and vaccine mandates, is due to expire on April 12.

Health Minister Martin Foley expects it will be extended but is awaiting updated health advice.

Despite vaccine immunity waning over time, he said the double-dose vaccine mandate for hospitality patrons has helped mitigate the spread of COVID-19 and should stay for now.

"The vaccinated economy has made a significant contribution," he said.

"So keeping those (restrictions) in place until we see the downturn of the BA.2 sub-variant seems to be at the heart of the direction that AHPPC (Australian Health Protection Principal Committee) wants the states and territories to go."

Opposition Leader Matthew Guy, who returned to state parliament on Tuesday after isolating as a close contact of his infected nine-year-old son, said it was time to move on from vaccine mandates in most settings.

"It's about time we moved on with our lives, sensibly," he said.

There are currently 331 people in Victorian hospitals with the virus, including 16 intensive care patients.

Three more people have died.

Meanwhile, traditional Anzac Day activities in Melbourne will revert to normal this year after two COVID-disrupted years.

RSL Victoria confirmed people planning to attend the dawn service, march or commemorative service in the city won't need to register and their vaccination status will not be checked.

A third person has been charged with murder in relation to the disappearance of missing Queensland man Lachlan James Griffiths.

A 28-year-old man was arrested during a police search of a Brisbane residence on Tuesday and will face the Caboolture Magistrates Court on Wednesday.

His arrest follows that of Francescos Giorgi, 40, who was charged over Mr Griffiths death following a raid of a Gold Coast hinterland property on March 24.

A 40-year-old Tingalpa man has also been charged in relation to the alleged murder.

Mr Griffiths, 35, was last seen alive in the Brisbane CBD in January, before his mother reported him missing on Australia Day.

Queensland Police believe Mr Griffiths was taken by car to a Coopers Plains transport depot but are yet to find a body.

His alleged death is linked to that of 35-year-old Andrew Christopher Walsh, whose body was found encased in concrete at the same transport depot last month.

The depot is the common link between the men, but detectives don't believe Mr Griffiths' remains are buried there.

Mr Walsh was reported missing by family in the north Queensland town of Mossman in January, however detectives say he was last seen alive at Slacks Creek in November.

David Lee Tan, 39, Dewald de Klerk, 27, and a 39-year-old Thagoona man have been charged with being an accessory after the fact of Mr Walsh's murder and misconduct by interfering with his corpse.
