These Games were the first to be staged in the Southern Hemisphere and Oceania, as well as the first to be held outside Europe and North America. Melbourne is the most southerly city ever to host the Olympics. Due to the Southern Hemisphere's seasons being different from those in the Northern Hemisphere, the 1956 Games did not take place at the usual time of year, because of the need to hold the events during the warmer weather of the host's spring/summer (which corresponds to the Northern Hemisphere's autumn/winter).
The Olympic equestrian events could not be held in Melbourne due to Australia's strict quarantine regulations, so they were held in Stockholm five months earlier. This was the second time that the Olympics were not held entirely in one country, the first being the 1920 Summer Olympics, which were held in Antwerp, Belgium, with some events taking place in Amsterdam and Ostend. Despite uncertainties and various complications encountered during the preparations, the 1956 Games went ahead in Melbourne as planned and turned out to be a success. The enduring tradition of national teams parading as one during the closing ceremony was started at these Olympics.
