Young Scientists of Australia

The Young Scientists of Australia are a collection of not-for-profit organisations dedicated to the promotion of science in Australia to the 14-25 year old demographic. The chapters are located in Adelaide, Brisbane, Melbourne and Sydney and are run independently.
Operations.
The chapters' primary operations are organising science shows and workshops. These target high school students, primary school students and the general public, and vary from hour-long activities to the three-day ConocoPhillips Science Experience. Events are often run in partnership with universities, schools, museums, not-for-profits and corporate entities, by volunteers. Each chapter organises social events for its members. Popular socials include beach walks, Easter Egg hunts, Amazing Races, Game of Assassins and annual balls.
The National Conference is where members of each committee come together to discuss each chapter's challenges and opportunities, and to provide direction for YSA as a body. The conference is held annually and runs for two to three days.
