Queensland chief health officer Jeannette Young said the risk associated with a man who accidentally moved through a green zone in Brisbane Airport before testing positive to coronavirus was "less and less".
The man and his companion were mistakenly directed into the airport's green zone after arriving on a flight from Papua New Guinea about 9.45am on Thursday.
The man's initial test failed to deliver a concrete result before further testing confirmed he was positive. His companion tested negative.
Dr Young said that with his serology results indicated to her he's right at the end of his illness.
"He could almost be fully recovered," she said.
"We know that the risk is always in that 48 hours before someone develops symptoms, at the start of their illness. He's right at the end and he's well."
Dr Young has declared the international terminal a venue of concern.
In Federal politics today, former Liberal staffer Brittany Higgins has met with Prime Minister Scott Morrison and Labor leader Anthony Albanese about reforming the toxic workplace culture faced by political advisers.
After their meeting, Mr Albanese told reporters Ms Higgins' reform ideas were "modest and reasonable".
"She has shown extraordinary courage in coming forward - to be a voice standing up for women, standing up for issues that need real solutions," he said.
Mr Albanese said there was a need for an independent body for staff members and MPs to seek advice and raise workplace issues.
In Western Australia, Dr Vafa Naderi has been found guilty of professional misconduct over failing to properly examine an Aboriginal woman before she died in custody.
Ms Dhu, 22, whose first name is not used for cultural reasons, died two days after being locked up at South Hedland Police Station, in the Pilbara region, in August 2014.
She died during her third visit in as many days to the Hedland Health Campus from staphylococcal septicaemia and pneumonia after an infection in her fractured ribs - caused by her partner - spread to her lungs.
The Medical Board of Australia pursued action against Dr Naderi, accusing him of professional misconduct, and on Friday he was ordered to pay a fine of $30,000 to the medical board, as well as paying its costs.
Dr Naderi was also ordered to complete a report demonstrating how he had incorporated lessons from the incident into his practice.
