Queenslanders will find out this morning if the state's health officials are comfortable enough with the latest COVID-19 numbers to lift the lockdown at 4:00pm.
The state recorded only 13 new cases on Saturday, all tied to the cluster, which started with a western suburbs school student and has now grown to 102 active cases.
All of Saturday's cases were in quarantine during their infectious period.
Both the Deputy Premier Steven Miles and the state's Chief Health Officer Jeannette Young appeared satisfied with the developments on Saturday but said any decision would hinge on Sunday's numbers.
Mr Miles said the results were "very, very encouraging" and urged Queenslanders to "keep it up".
"If we do, that is what will give us the best possible chance of starting to get closer to what is normal as soon as possible," he said.
"It is important to know we will see continued cases, many people in households … will continue to catch the virus in the coming days and weeks.
"What is most important is that they are not outside of their household, they are not infectious in the community."
With respect to relaxing restrictions, Dr Young said she would have to see "how we go".
Concerns about undetected cases may play a role in any decision.
"This outbreak has only been going for a short period, so there still could be cases there,'' said Dr Young.
Today's press conference is expected to feature the first appearance of Premier Annastacia Palaszczuk since she returned from the Olympics, and went into hotel quarantine in Brisbane.
Mr Miles said the premier had recorded a negative test and has been released.
"She will come straight to work, and she is looking forward to being here with us for the press conference,'' he said.
New vaccination priorities
Queensland school staff and childcare workers have been announced as new priority targets for COVID-19 vaccinations, in the wake of the Delta strain outbreak.
Premier Annastacia Palaszczuk said in a statement this morning, the groups would be added to Queensland's 1B priority list.
Cresta Richardson from the Queensland Teacher's Union said the decision had been a long time coming.
"This is something that we've been calling for all year," she said.
"It's something that many of our members have been seeking so we're really happy that the health and safety of teachers and those adults in schools are being recognised as a priority."
FIFO, freight and distribution centre workers have also been added to the "high-risk" priority group.
Stuck in quarantine
Regardless of whether lockdown is lifted, more than 10,000 Queenslanders will still be stuck in quarantine after being caught up in the outbreak and classified as close contacts.
For Brisbane resident Glen Sanderson, all it took to end up in quarantine was for a family member to visit a supermarket.
The health worker from The Gap in Brisbane's northern-western suburbs and his family were isolating after his daughter was listed as a close contact of a case at Woolworths Ashgrove on July 29.
"Shocked and annoyed'' was how he described feeling after getting the news.
"But I was waiting for it because of the school connections but also sporting connections as well,'' he said.
"I thought there might be something through that."
Mr Sanderson said friends, neighbours and family had been "awesome" dropping off care packages and doing supermarket drops.
"So we're doing very well. We are very lucky,'' he said.
"[We've received] so many emails and texts asking if we're all right and if we need anything. All the parents from the netball team have been checking in on us."
The family members have all tested negative but will be tested again on day 12.
Lockdown breaches
Meanwhile, authorities expressed frustration about people breaching lockdown, including trying to cross state borders and refusing to wear masks or stay in lockdown.
In the past 24 hours, 42 people have been issued with Penalty Infringement Notices (PIN) for not having a valid excuse for being out, and 16 people were issued PINs for not wearing a mask.
Deputy Commissioner Steve Gollschewski said there was a small group of people persistently doing the wrong thing.
"Unfortunately, we also saw four arrests yesterday," he said.
"We had two persons at Noosaville who not only refused to check in with the check-in app, then refused to wear masks and then decided to have an argument with police and resist the arrest."
