Queensland has recorded another four deaths and 7,311 new COVID-19 cases but its chief health officer is confident the state's Omicron wave is almost over.

The new cases emerged after 24,875 tests in 24 hours across Queensland including 2066 RATs.

Of the four deaths, three were in aged care, none had a booster and one was vaccinated.

Three of the victims were aged in their 80s and the other in their 90s.

CHO John Gerrard was quietly confident the state's Omicron wave had almost passed due to the latest hospital numbers.

There are currently 462 COVID-19 patients in public hospitals (down from 508 on Saturday) with 44 in intensive care and 20 on ventilators.

In private hospitals there are 34 COVID-19 patients.

"The data I find most useful in tracking this pandemic is the hospitalisations data, and this is taking a really positive turn," Dr Gerrard said.

"Just 19 days ago we were at our peak of 928 patients. In 19 days we have halved the number of people in our hospitalisations.

"We are well on track to coming to the end of this wave of infection. Things are going far better than we had ever projected in terms of this Omicron wave."

The state government said 3.5 million RATs had been distributed to public health services with another 1.5 million arriving this weekend.

Dr Gerrard believed the state was on track despite predicting a "significant rise" in children's cases following the return of school last week.

He said about 1000-1500 children had been diagnosed with COVID-19 every day across the state since school resumed but "almost all of them have a very mild disease".

He said "roughly" half were in primary school and the other in secondary.

There were 1113 new children cases from PCR tests in the past 24 hours and 652 from RATs.

"There is is still no clear trend in children but it is very early," Dr Gerrard said.

"It would be a very big surprise if we don't see a significant increase in the number of children in the next couple of weeks."

The latest figures show that 92.36 per cent of eligible Queenslanders have had one dose of a vaccine, while 90.31 per cent have had two.

In booster numbers, 61.15 per cent of eligible Queenslanders have had a third shot.
