Authorities are on high alert this morning after a Sydney man repeatedly broke NSW's tough Covid rules to fly to Queensland, putting the Sunshine State at risk.

The man has emerged as the "missing link" to a Qantas flight attendant who has tested positive to the Delta strain.

The Sydneysider flew to Queensland despite not being permitted to leave Sydney, and after being informed he was a close contact of a positive case, which meant he was required to isolate at home.

He later lied to authorities, telling them he was at home in Sydney despite already having made it to Queensland.
