Queensland has recorded another 13 deaths from COVID-19 and confirmed 10,212 new cases in the latest reporting period.
Chief Health Officer John Gerrard said there were 878 people in hospital, including 50 patients who are in intensive care.
"It's early but the number of people in hospital appears to be significantly lower than we had expected at this stage," he said.
"This, we believe, has to do with people's changing behaviour in avoiding getting infected."
Of the state's 13 deaths, four people were in their 70s, seven in their 80s and two in their 90s.
Three were unvaccinated, one had received one dose of a COVID-19 vaccine and nine were fully vaccinated.
None had received a booster dose.
Dr Gerrard said the number of people in hospital on the Gold Coast has "declined slightly every day for the past four days".
He said the Gold Coast was likely to be the first area to peak and Brisbane should follow within seven days.
"So it would appear the Gold Coast is close to or passed the current peak," Dr Gerrard said.
"That means that we've got very significant transmission in the community at the moment and the end will not be for a number of weeks.
"We won't know for a week or so when we hit the general peak for Queensland, particularly for south-east Queensland, exactly how high that peak of hospitalisations would be but we were certainly anticipating several thousand people in hospital."
Vulnerable Queenslanders told to get booster, minimise movements
Premier Annastacia Palaszczuk said from today, Queensland residents will be eligible for their booster shot three months after their second.
"We said to Queenslanders that we expect these next two weeks are very critical in terms of reaching that peak of the Omicron wave," Ms Palaszczuk said.
"Of course the Gold Coast has seen higher figures than Brisbane and the regions but we expect that Brisbane will essentially be reaching its peak over the next couple of weeks and of course some parts of regional Queensland as well.
"My message is, to the vulnerable members in our community, those elderly senior residents, about minimising your movements."
Dr Gerrard said it was possible Queensland would see an "extension of the peak" when school recommences in two weeks.
"So it may well be we have a longer flatter period because of schools which is really what is ideal because the whole purpose of a lot of our measures has been to reduce the impact on hospitals in Queensland," he said.
"At this stage, Queensland hospitals are bearing up.
"We'll see in the next seven days, particularly as metropolitan Brisbane peaks, just exactly what happens there."
Health Minister Yvette D'Ath said 21 per cent of people who have died with COVID in Queensland were unvaccinated.
"Only 8.2 per cent of our population over the age of 16 are unvaccinated, so they only make up just over 8 per cent of our population currently, but they make up 21 per cent of our people who have died with COVID," Ms D'Ath said.
"Of the 111 deaths, we've only seen five people who have had their boosters.
"So it shows the benefit of vaccinations."
The Premier said 25.72 per cent of children aged five to 11 had now received a dose of COVID vaccine.
She said a plan for how schools would deal with COVID during the school year would be released this week.
