The Embassy of Hungary represents Hungary in Australia.
Citizens of Australia, Kiribati, Solomon Islands and Vanuatu don't need a tourist visa if they're travelling to Hungary for less than 90 days. Australian residents will need to apply for their Hungarian tourist visa at the Swiss Consulate General in Sydney.
