Austria and Germany share close cultural, economic and historical ties. While Austria was once part of the Holy Roman Empire and later the Austro-Hungarian Empire, it has established its own distinct identity.
Some of the main differences between Austria and Germany are:

Language: While German is an official language of both countries, Austria speaks Austrian German which has some vocabulary and pronunciation differences compared to Standard German spoken in Germany.

Government: Germany is a federal parliamentary republic while Austria is a federal parliamentary representative democracy. 

Economy: Germany has the larger economy and is a global economic powerhouse known for industry and manufacturing. Austria has a smaller, more service-based economy and is known for its tourism, particularly in mountainous regions. Austria adopted the euro while Germany kept the deutsche mark.

Culture: Both embrace beer, sausages and oktoberfest celebrations. But Austria is strongly influenced by its past as part of the Austro-Hungarian Empire with elements of Central European culture, while Germany looks more to Northern European traditions.

Geography: Germany lies mainly in Northern Europe while Austria spans Central Europe. Austria is mountainous with the Alps covering 60% of its land area, giving it a very different landscape compared to low-lying northern Germany.

History: Germany unified in 1871 but Austria was left out. Austria was once a powerful empire but lost relevance after World War 1 when it lost territory. Germany faced division after World War 2 but was reunified in 1990.

While Austrians and Germans share close ties, emphasize their differences and each country has forged its unique path since Austrian independence after World War 1. Both continue to be important trade partners at the heart of Central Europe.  - https://mbscore.tv/match/austria-vs-germany-18972840
