Queensland is "not going to deviate" after reopening its borders, the chief health officer says, amid concerns about the Omicron variant of COVID-19.
Four new cases - including one Omicron - emerged after 10,657 tests in the 24 hours to 6.30am on Tuesday, but all were in home or hotel quarantine.
Chief Health Officer John Gerrard said it is too early for cases to be rising in the state after quarantine was scrapped for vaccinated travellers from domestic hotspots on Monday.
Queensland's travel rules are also unlikely to be tightened because of Omicron, he said, as it is too soon to tell if the variant is causing a rise in hospitalisations globally.
"We're certainly watching that with with great interest, but we're not going to deviate from our current plan," Dr Gerrard said.
Deputy Premier Steven Miles was confident cases would remain manageable over Christmas with restrictions such as localised lockdowns highly unlikely.
He said Monday's border opening had been timed for when the vast majority of Queenslanders has been vaccinated, which would ensure the festive season would pass without major outbreaks.
"The modelling suggests that even as cases start to arrive, they won't be reaching peak kind of levels until into March next year," Mr Miles told reporters in Brisbane.
However, Dr Gerrard said as cases rise over coming months there was a chance an indoor mask mandate could return.
He said an indoor mandate was being discussed every day, but it would only be ordered if there was evidence of widespread and sustained community transmission of the virus.
"It's probably a little warm in Queensland for outdoor mask mandates and they're probably not so critical," he said.
Meanwhile, as a vaccine mandate came into effect for Queensland's private hospitals, aged and disability care facilities on Wednesday, Dr Gerrard said he expected all health care workers to be double-dosed.
He said any remaining vaccine hesitancy among the state's residents had been "melting away" in recent days.
"It is likely that all of them will get vaccinated," the CHO said.
"There have been very few health care workers that have not been vaccinated."
Mr Miles said health providers would only have to check if people entering private facilities had a green tick on their check apps from Wednesday.
He warned people visiting private health facilities to ensure they complied with the vaccine mandate.
"Any enforcement beyond that, that is the job of police and police have said that they take that job very seriously," Mr Miles told reporters in Brisbane.
Meanwhile, unvaccinated people will be banned from attending most Queensland venues, including cafes, restaurants, nightclubs, stadiums and theme parks from Friday.
Dr Gerrard warned the venue mandate was here to stay, and it would be a longstanding policy.
"We are not even looking at removing the mandate. It is not even something that is on the agenda," he said.
"It's not fair on the vaccinated to ask them to make sacrifices for the very small number of people who have not become vaccinated."
Overall 82.03 per cent of eligible Queenslanders are fully vaccinated and 88.61 per cent have had one dose.
