Hundreds of people are being warned to watch out for measles symptoms after it was revealed a passenger on board a flight into Sydney Airport had the highly contagious disease.
The man in his 20s flew from Manila aboard QF20 which landed in Australia on Friday about 6.30am.
He then visited a medical centre in Leichhardt where symptoms were identified and isolation measures put in place.
NSW Health on Monday said passengers on the Qantas flight and people at the airport on Friday morning should be alert until late January for symptoms such as fever, sore eyes and a cough.

"If you develop symptoms, please call ahead to your GP so that you do not wait in the waiting room with other patients," communicable diseases director Vicky Sheppeard said in a statement.
NSW Health said people travelling to Southeast Asia where measles is prevalent should ensure they are fully vaccinated before setting off.
"Outbreaks of measles in popular tourist destinations means the risk for measles being imported into Australia at the moment is high," a statement said.
Six people have been diagnosed with measles in NSW since Christmas.
Symptoms usually occur about 10 to 12 days after infection. The measles-mumps-rubella vaccine is free for people aged one to 52.
