Two new cases confirmed overnight in the Sunshine State were linked to detention centre cluster, which has a total of nine infections after a worker was diagnosed with the virus on Wednesday.
The 77-year-old Ipswich worker had experienced mild symptoms and continued to work while infectious.
The two new cases include a woman in her 30s and a baby boy from the West Moreton region. Queensland Health confirmed the baby has not been in childcare or family day care.
This prompted health authorities to publish an alert for locations centred mainly around the area of Logan, south of Brisbane.
Chief Health Officer Dr Jeannette Young cautioned further venues may be advised as contact tracing continues.
“These are not the only venues these people attended, but they are the ones we are most concerned about as a potential risk,” Dr Young said on Sunday.

Those who visited the identified locations are urged to get tested even if they’re suffering even the mildest symptoms.
‘We're not out of the woods yet’
Queensland Premier Annastacia Palaszczuk said on Sunday more than 200 of 500 staff at the Wacol centre had tested negative and more than 110 youths had returned negative results.
Health authorities are prioritising testing at the detention centre after all the 127 detainees were placed into lockdown on Wednesday evening.
"The results overnight are encouraging but of course we're not out of the woods yet," Ms Palaszczuk told reporters.
More than 100 staff members from the Department of Justice and additional officers from police and corrective services will come on board as current staff undergo quarantine.
The children are now being allowed out of their rooms in controlled groups.
"I want to assure parents we're taking good care of (them)," Department of Youth Justice director-general Bob Gee said.
Queensland has 16 active coronavirus cases. The cases at the centre mark Queensland's first locally acquired transmissions in more than a month.
As a result, the premier on Saturday capped indoor and outdoor gatherings without a COVID-safe plan in Queensland's southeast to 10 people and announced a 30-person limit on gatherings elsewhere in the state.
"I know there are disappointed people out there," Ms Palaszczuk said on Sunday.
"We have to put public health and community health first."
Authorities face a nervous wait to discover if the cases are genomically linked to an outbreak triggered by two Logan women who dodged quarantine following a visit to Melbourne in June.
