Aussie schoolies have been told to check they're vaccinated after 27 Australians caught measles while holidaying in Bali recently.
Health authorities have told travellers, especially young school leavers, to the Indonesian island to ensure they are vaccinated against the highly infectious disease before they leave.
There have been 27 cases of measles connected to travel to Indonesia, particularly Bali, across Australia in recent weeks, NSW Health says.
There have been 29 measles cases in NSW this year, 20 of which were acquired overseas or interstate or were closely linked to these cases.
More than a quarter of these have been linked to those in Bali.
