If you're going overseas, visit the Smartraveller website for advice on staying healthy while travelling. Information on vaccinations, disease outbreaks, prescription medicines and medical emergencies is also available.
Some countries require proof of vaccination against specific diseases before you can enter them. Smartraveller.gov.au has travel advice so you can find out what you need to do. If you are not vaccinated, you may be refused entry or be required to have the vaccination at the border.
