The state of Victoria will be declared as a hotspot by Queensland authorities from 1am tomorrow, which means any Queenslanders returning home after that point will need to do 14 days of mandatory quarantine.
"It is a clear message to Queenslanders. Definitely do not go to New South Wales and do not go to Victoria during this period of time, but we do wish everyone the very best and we know that Victorians get on top of these issues very quickly," Premier Annastacia Palaszczuk said.
The announcement comes as the state records just one new case of COVID-19 from the past 24 hours - the mother of the boy whose positive test was announced yesterday along with her partner.
It has also been confirmed that this Newport family has the same Delta strain that is found in Sydney.
"The people in Sydney, the health staff there, will be working through how he acquired the infection while he was in hotel quarantine down there," Chief Health Officer Dr Jeannette Young said.
"He's come up here and he had very little exposure out in the community," she said.
Dr Young explained the boy's father had minimal exposure in the community, and his mother had virtually none because she went into hospital with her son when he was admitted. There have been 62 contacts identified in relation to this outbreak so far.
Out of the three cases that were reported yesterday, the airport worker has a strain of COVID-19 that is "four snips different" to the previous COVID-19 airport worker reported, meaning there hasn't been direct transmission between the two.
The Tarragindi woman is a supervisor at one of the boarding gates at the Brisbane International Airport, and CCTV footage has identified 23 close contacts and 22 casual contacts. It is expected there will be more.
