Kimberley O’Brien grew up competing in athletics and playing representative AFL. After seeing one of Circa’s shows, Kim joined Circa’s youth performance troupe Circa Zoo in 2008.

After two years of training and performing Kim was given the opportunity to be the first member of Fast Track, a program designed for young and aspiring performers within Circa.

In 2011 Kim left Circa Zoo to be a full-time ensemble member. Since then, Kim has toured numerous shows in various countries and performed in over 30 Circa shows. One of her highlights was performing Wunderkammer at the Sydney Opera House in 2012.
