Such is the scale of the modern-day Asian Games there were 13,000 volunteers required for the duration of the event, including 2,000 in Palembang alone.
Places were available for high-profile roles such as protocol assistants, National Olympic Committee assistants and liaison officers, all of which are vitally important to the smooth running of the event.
Those interested in applying could do so through the official Jakarta-Palembang 2018 website, which opened on January 18.
The Asian Games test event, due to take place in Jakarta from February 10 and 24, needed 2,000 volunteers.
Following a first phase of registration for volunteers, a second phase begun in December 2017 and was for the actual 2018 Asian Games themselves.
Most volunteers were aged between 19 and 50.
Each wore specially-designed, distinctive, eye-catching uniforms.
"Every volunteer should raise the enthusiasm and excitement of the Games, by implementing their roles with responsibility and assisting delegations in a friendly manner, especially by showing the Indonesian spirit of hospitality," the Indonesia Asian Games 2018 Organising Committee (INASGOC) said.
Volunteers came from far and wide as seen in the general public and, in particular, students applying to play their part.
Having foreign language skills and a passion for ensuring a successful Asian Games were considered key requirements.
In addition to volunteers, there was a 5,000-strong paid workforce on duty during the Asian Games.
The Opening and Closing Ceremonies, at the Gelora Bung Karno Stadium in Jakarta, featured around 10,000 performers.
