"More locations may be added after it was revealed the Strathpine man hosted a gathering of around 25 people at his home between being instructed to isolate and getting his positive test results", the department said. All the guests have been ordered into quarantine and will undergo testing.
"What we've identified through the investigation and what police have found and Health have found is thankfully, it was not 25 people".
A source close to the two infected men told The Sunday Mail both were partying in Fortitude Valley last Friday night, a day before authorities started tracking the whereabouts of the first man.
"I think there's a good chance he's shared it amongst 25 people, depending on what kind of party it was, whether it was indoors, whether there was some fresh air coming, whether there was a decent ability to remove aerosol", he said.
"They are important risk areas.
Now we need to do this now to avoid a longer lockdown", Premier Palaszczuk said.
Premier Annastacia Palaszczuk said six of the cases were overseas acquired but four were local - two directly linked to the recent cluster.
"And that is of now concern to Queensland Health and of course concern to me".
One of those visited Gladstone for three days while infectious, Dr Young said.
The potential for another damaging lockdown ahead of the busy Easter holidays becoming more real in the wake of the COVID house party.

"They have recently been in Byron Bay during their infectious period", Doctor Young said.
The promise came after a doctor at Princess Alexandra Hospital in Brisbane was discovered to be carrying the United Kingdom variant of Covid-19 on March 12.
Ms Young said 18 contacts of the Stafford man had been traced so far, but numerous venues he visited were not required to have electronic check-ins. It also advises that anyone who falls into that category and went to Mamma's Italian Restaurant in Redcliffe from 12.30-3.10pm on Sunday, March 21 must get tested immediately and go into isolation for 14 days.
Ms Palaszczuk urged people not to panic buy and said supermarkets were well stocked.
She said very late last night she was notified of another case, who was the PA hospital nurse who worked in the COVID-19 ward.
But Mr Morrison said the risks that sparked Queensland's border closures past year had changed and the state should adopt "a balanced approach here".
"It was important information that we put out, based on the facts we had at the time, because if we had not, and that had gone out in some other way, then we would not be transparent about what we knew. They've got a strong tracing system".
Ms D'Ath said the most high-risk locations were cafes and restaurants that the positive cases had attended.
"So we now have significant community transmission and significant numbers of venues of concern, all through Brisbane and we know that people have moved from Brisbane out into the broader community".
Health Minister Yvette D'Ath defended the government's release of the incorrect information, saying it was the information officials had at the time.
