"The response to the current COVID-19 outbreak in Queensland is no different, with people who have been in specific locations in Brisbane and in Byron Bay being asked to self-isolate and get tested", he said.
She said of the hens party which involved the two positive cases who visited Byron Bay, one is a NSW resident but is now staying in Queensland and is being tested there.
One is a nurse from Brisbane's Princess Alexandra Hospital, who was exposed to a COVID-19 patient, and the other is her housemate.
"So that's a linked case" Chief Health Officer Dr Jeanette Young said.
"She has since developed some symptoms". So we just need to work out how she got it on that ward.
The previous phase was meant to vaccinate aged care staff and residents, and frontline health workers and others involved in quarantine programs.
The cluster linked to the nurse now stands at 11 cases, while another cluster linked to a doctor at the same hospital stands at eight cases.
Less than one day before it was scheduled to kick off, the 2021 instalment of Bluesfest has been cancelled.
NSW Health is also asking everyone else in the area - or those who were there over the weekend - to monitor for symptoms and get tested if any eventuate. "The fact that we do not have any unlinked community transmission in the south-east or in our state is absolutely encouraging news".
"They must also make sure they check in to venues; this will make it easier for contact tracers to do their vital work".
"This is fantastic news that over the past 24 hours, there have been 33,408 tests".
"We are expecting more cases from Queensland and hopefully most of those cases will be people in isolation although we have to assume this is an evolving situation", Ms Berejiklian said. That is a massive, massive number. I think the figures speak for themselves.
"I do want to thank Queenslanders for coming out and doing that".
"So if we see the same number of test results tomorrow, this is very, very encouraging news".
"We are doing a great job and together we will get through this".
She said a decision on extending or expanded Greater Brisbane's lockdown would depend on what the numbers looked like on Thursday morning.
"I'm urging anyone who was in Byron on that weekend to please be particularly vigilant as to any updated information", Dr Chant said.
"While the cancellation of Bluesfest is disappointing for music lovers and the local community, I hope that ticket holders would support Bluesfest and hold on to their tickets as I understand Bluesfest will be working on a new date as soon as possible", Minister for Health Brad Hazzard said.
"We won't be policing that but it is very strong advice. if there is community transmission, we don't want it seeded to other parts of NSW".
Festival organisers have a government-approved Covid-19 safety plan in place after the event was cancelled past year, but the Queensland outbreak could put the Easter event in jeopardy.
