Aussie travellers have been warned to brace for “disruptions” at airports across the country as more than 1000 workers walk off the job as part of a push for better conditions.

NSW Health said anyone transiting through Sydney’s international and domestic airports on January 17 should watch for measles symptoms for at least another 10 days.

Health officials have issued a measles alert for two major Aussie cities after the highly infectious and deadly disease was detected from travellers in Sydney and the Gold Coast.
