Pregnant women are being advised to consider postponing travel to Indonesia, with the Australian government updating its travel advice to warn the country is experiencing sporadic transmission of the mosquito-borne Zika virus. 
The virus has been linked to microcephaly - a birth defect that has seen thousands of babies in Brazil born with unusually small heads and often severely compromised.
On its smart traveller website, the government says it advises all travellers to Indonesia to protect themselves from mosquitoes.
"Given the possibility that Zika virus can cause severe malformations in unborn babies, and taking a very cautious approach, pregnant women should discuss any travel plans with their travel doctor and consider postponing travel to Indonesia," it says.
The overall travel advice has not changed, with Australians advised to exercise a high degree of caution in Indonesia, including Bali.
This week the Indonesian Ministry of Health launched an investigation in the village of Tangkil in East Java after Taiwanese authorities advised that an Indonesian from the area had been diagnosed with Zika. The 22-year-old sailor reportedly arrived at Taiwan's international airport on   June 2 with a fever and red eyes.
