Australian travellers are being warned against travel to Bali due to the prevalence of the Zika virus.
The Australian Department of Foreign Affairs and Trade has asked travellers to Indonesia to exercise a "high degree of caution".
"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 the travel doctor and consider postponing travel to Indonesia," a statement from the department said.
The warning advises travellers to Indonesia to protect themselves from mosquito bites.
Travel Doctors' Jennifer Sisson told the NT News the risk of transmission in Indonesia was relatively low, but not non-existant.
