Queensland has recorded a case of Covid-19 in the community, with the source of the infection so far a mystery.
Queensland Health said the man was in his 30s and worked in aviation.
A public health alert has been issued for places in Eatons Hill, Aspley and Albany Creek on Brisbane's north side, as well as a truck seat company at Rocklea in the city's south.
The Mother Duck childcare centre and kindergarten at Eatons Hill had been identified as a casual contact site last on Thursday morning.
