DIBP Polio and Visa Application Update
Visa applicants who have spent 28 days or longer in Afghanistan, Cameroon, Equatorial Guinea, Ethiopia, Iraq, Nigeria, Pakistan, Somalia or Syria, or in any combination of these countries, on or after 5 May 2014 should provide a vaccination certificate as evidence that they have been vaccinated against polio if they are applying for a visa from outside of Australia. This is in response to the World Health Organization’s declaration of polio as a public health emergency of international concern.
