I want to know the answer to the following question:
Previous to Melbourne, where were all Olympic games held?
All the background I'm provided with is that "Melbourne is notable as the host city for the 1956 Summer Olympic Games (the first Olympic Games held in the southern hemisphere and Oceania, with all previous games held in Europe and the United States), along with the 2006 Commonwealth Games.". Is that enough to answer the question?
Answer: yes
