The Australian team features the oldest and youngest athletes of the entire championships. 49-year-old Kelly Ruddick is entered for the 35km race walk, while 17-year-old Claudia Hollingsworth will contest the 800m. Ruddick will become the oldest ever athlete to compete in a women’s discipline at the World Championships.

Official start lists will become available after the technical meeting on the eve of the championships.
