The Culture
In Austrian society, formalities and etiquette are key. Small greetings are worth it — it's considered rude to enter a shop without saying Guten Tag (hello) or Auf Wiedersehen (goodbye). When drinking alcohol, don't forget to toast with "prost" or "cheers".
You'll hear German being spoken in the streets, as it's the official language of the country. Austria and its people are unique, so avoid comparing it to Germany. Dialects like Alemannic and Austro-Bavarian are also spoken in some parts of the country. Typical, it isn't hard to find people who speak English.
Roman Catholic is the majority religion in Austria, with smaller followings of Buddhism, Protestantism, Orthodox Christianity, Islam and Hinduism.
