Contact tracing is being conducted around those flights,Chief Health Officer Jeannette Young said. Dr Young said she had also asked WA health authorities for details of his test conducted in that state.

The man largely kept to his room after he began to feel unwell,following his July 20 return from Perth.

Test results for three people linked to the hostels who were out during the day on Wednesday are still outstanding,with those staying at the City Backpackers and Joe’s Place sites to remain there until health authorities are comfortable.

After a man was taken away by paramedics on Thursday morning,Queensland Health was not yet aware of an additional positive case but a spokeswoman said there could be a number of reasons why a person may need hospital transport.

The hostels,the return flight from Perth,Brisbane Airport and the Royal Brisbane and Women’s Hospitalhave been listed as exposure sites.

Ms D’Ath said 11 crew members on the MV Sanyu docked in Weipa on Cape York — two of which have tested negative — remained on board to crew the vessel after 10 infected with the virus were transferred to Brisbane hospitals.

After Ms D’Ath revealed CCTV footage had found no clear point of transmissionfor another returned traveller who tested positive earlier this week after leaving hotel quarantine,and contact tracing sites added yesterday related to a recent border breach by an infected NSW man,Dr Young said it was too early to lift mask restrictions.

“I think that it has protected us from getting further spread out into our community and we’re just seeing so many of these cases pop up from so many different places,” Dr Young said.

Mandatory mask use was extended in the 11 south-east council areas from an initial two weeks following the state’s last snap lockdown lifting on July 3.

That has now been extended for a third additional week under what some experts say is ashift in the state’s approach to managing the pandemic.
