Queensland Health has blamed Victoria's chief health officer for a COVID-19 scare involving a former bikie who flew into Brisbane from Melbourne.
Shane Bowden, 48, a former Mongols gang member, flew from Melbourne's Tullamarine airport to Brisbane aboard Jetstar flight 560 on Monday morning.
Both Premier Annastacia Palaszczuk and Deputy Police Commissioner Steve Gollschewski had advice from Queensland Health that he had COVID-19.
Their announcement sparked a virus scare among the 84 other passengers on the plane.
Queensland Health later announced that he did not have the virus on the flight.
It is understood that Chief Health Officer Jeannette Young received an email from her Victorian counterpart Dr Brett Sutton warning her about Bowden ahead of his arrival.
"Initial advice from Victoria Health was a Victorian resident had received a positive test result and was therefore infectious on the flight to Queensland," Queensland Health said in a statement to AAP on Wednesday.
"We acted swiftly on that advice and informed the public, as we have done throughout this pandemic."
Dr Sutton told a press conference later on Tuesday that no known cases have flown out of Melbourne.
Queensland Health said they only received fresh advice later that afternoon from their Victorian counterparts that Bowden did not actually have the virus.
"A public health alert was not issued for the flight given the new advice received from Victoria Health," the statement added.
Bowden is currently in mandatory hotel quarantine in Brisbane along with other passengers.
Mr Gollschewski said on Tuesday that Bowden was being investigated for lying on his Queensland border declaration and breaching quarantine in Victoria.
"This male person is well known to us," Mr Gollschewski told reporters.
No charges have been laid.
