In terms of size, the Austrian Open is third behind the GOC and the ROC. Approximately 3,000 athletes representing 50+ nations have entered this year's edition, which happens to be the 18th consecutive.
Organised jointly by the Austrian DanceSport Federation (ÖSTV) and its regional branch, the Viennese Federation, it relies wholly on a experienced group of people who, as enhusiastic volunteers, put in highly professional work to make the event happen year after year.
Here are a few photographs to make the point. Take the venue:
The Stadthalle is hired, but the AOC fit-out is applied by the volunteer force.
Ready for 1,500 couples to dance and for 8,000 spectators to watch!
