The state today recorded another 10 local cases of coronavirus, all linked to cases in Brisbane schools, swelling the cluster total to 89 cases.
About a dozen schools in total have been considered hotspots at some point in the outbreak.
Yesterday, Queensland Health confirmed two-thirds of the cases in the current outbreak were in children or teenagers.
Currently, only children over the age of 12 and adults are included in the state's mask mandate but that could soon change.
The state government says it is trying to source smaller masks that will properly fit younger children.
"There's very few places in the world that get children under 12 to wear masks so we will just work it through and see if it is beneficial and if we can do it," Chief Health Officer Dr Jeannette Young said.
"I have had young children, and trying to get them to keep hats on and all sorts of things… but it might end up being those young children in primary school."
Authorities have praised masks as being a key factor in preventing the current outbreak of the highly contagious Delta variant from escalating faster and further.
"If you think about where this outbreak spread, it spread in places that didn't have masks," Deputy Premier Steven Miles said.
"That just underlines how valuable masks have been in controlling spread in other places."
Queensland AMA president Dr Chris Perry told Today yesterday the outbreak was a "scary situation" particularly for parents.
"We don't know what it's going to do to the kids," Dr Perry said.
"Generally, you think it will be a mild illness but they could shed more virus than older people, therefore their parents are in the firing line, they want to be there with their kids.
"We're in a slightly scary situation."
The World Health Organisation and UNICEF advises that the decision to use masks for children aged between six and 11 be based on whether there is widespread transmission where they live, whether they pose a risk to elderly or vulnerable people, whether they can safely and appropriately wear the mask and any potential impact of wearing a mask on their learning and psychosocial development.
Use of masks is not recommended for children aged five and under, based on their limited capacity to use one safely and effectively, unless they are in contact with someone who is ill, in which case they should be supervised.
