A measles alert has been issued after a returned traveller who was infectious visited multiple places in Sydney.
The person recently returned from South-East Asia, where there are ongoing outbreaks in several countries including Thailand, Vietnam and Indonesia.
People who travelled on flight GA712 from Jakarta to Sydney which arrived in Sydney at 10.45am on Saturday, December 27, have been told to watch for symptoms of measles.

After the flight, the returned traveller was in the Sydney Airport International Arrivals Hall from 10.45am to noon on the same day.
The traveller was also in Blacktown Hospital's emergency department waiting room from noon on December 29 to 6am on December 30.
Western Sydney Local Health District acting director of public health Dr Conrad Moreira said anyone who visited the locations at the same time as the traveller should monitor for symptoms.
"If symptoms develop, see your doctor or health service, including emergency department," Moreira said.
"Call ahead to let them know that you may have come into contact with measles, so you don't spend time in waiting rooms with other patients.

"Symptoms to watch out for include fever, sore eyes, runny nose and a cough, usually followed three or four days later by a red, blotchy rash that spreads from the head andface to the rest of the body.
"It can take up to 18 days for symptoms to appear after an exposure, so it's important for people who visited these locations to look out for symptoms until January 17, 2026.
"Measles is a vaccine preventable disease that is spread through the air when someone who is infectious coughs or sneezes.
"We want to remind the community to make sure they are up to date with their vaccinations.
"The measles vaccine can prevent the disease even after exposure, if given early enough.
"This should be a reminder for everyone to check that they are protected against measles, which is highly infectious.
"Anyone born after 1965 needs to ensure they have had two doses of measles vaccine.
"This is especially important before overseas travel, as measles outbreaks are occurring in several regions of the world at the moment."
