Chief Health Officer John Gerrard is "pleasantly surprised" by Queensland's low number of school student infections after confirming another two COVID-19 deaths and 4265 new cases for the state.
Dr Gerrard said neither of the people who died had been vaccinated while one person was in residential aged care.
One was aged in their 70s and the other was in their 80s.
Dr Gerrard said the number of hospitalisations in Queensland has continued to decline in the past 24 hours.
In public hospitals, there are 365 people being treated for COVID-19 - down from 391 on Saturday - with 33 in intensive care.
In private hospitals, there are 21 being treated after there were 23 on Saturday.
"The situation in general with regards to COVID-19 in Queensland continues to improve significantly," Dr Gerrard said on Sunday.
He said schoolchildren cases had also fallen with 1381 reported in the 5-17 age group on Sunday, down from 1507 on Saturday - much to his surprise.
"There's been no significant increase in schoolchildren cases in the last couple of weeks since the schools opened and no increases in children admitted to hospital," Dr Gerrard said.
"I am pleasantly surprised. We thought there would be significantly more."
Meanwhile, Dr Gerrard said heading into winter the Australian Technical Advisory Group on Immunisation may need to consider whether people need a fourth jab.
He also "strongly encouraged" Queenslanders to get the flu vaccine when it arrives in April.
"There is a significant chance we will have both viruses this winter," he said.
Overall Queensland has 34,081 active COVID-19 cases after 9434 tests in the last 24 hours.
The latest figures show that 92.52 per cent of eligible Queenslanders have had one dose of a vaccine, while 90.58 per cent have had two.
