The vote was overwhelmingly in favor of Austria as it was a small country, a World Jamboree had never been staged there, Austrian Scouts had been forbidden in 1938 and had made their own comeback in 1946.

The majority of the countries represented at the Conference had been at war with the then Austrian State only five years before, and there was a great desire to show that the brotherhood of Scouting was a reality.

In voicing the invitation, the Austrian International Commissioner, Adolf Klarer, said that the Seventh Jamboree "would have to put up with great simplicity."

The Austrian government administered the country under foreign control, still divided into American, British, Soviet and French occupation zones.

Preparations were started immediately, and the site near Bad Ischl in the Salzkammergut was selected in November 1949 while snow lay on the ground.

Other key events included the official opening and closing of the campsite, a bridge building competition for partaking Scouts, and two bonfire evenings for both participants and visitors of the Jamboree.

Contingents came from Algeria, Armenia, Australia, Belgium, Bolivia, Brazil, British Guyana, Burma, Cameroon, Canada, Ceylon, Chile, Cuba, Cyprus, Denmark, Germany, Egypt, El Salvador, France, French Equatorial Africa, French West Africa, Gibraltar, Great Britain, Greece, Hong Kong, Iceland, India, Iraq, Ireland, Italy, Jamaica, Japan, Kenya, Lebanon, Liechtenstein, Luxembourg, Madagascar, Malaya, Mexico, Morocco, Malta, the Netherlands, New Zealand, Nigeria, Norway, Pakistan, Portugal, Sierra Leone, Southern Rhodesia, South Africa, Sudan, Sweden, Switzerland, Syria, Togo, Tunisia, the United States, Venezuela and Vietnam.
