The COS Story
COS was founded in 1976 by Dominique Lyone, the son of an Egyptian immigrant whose family ran awayay to Australia after the 1967 Six Day War. Following in the footsteps of his daddy, the owner of a small typewriter repair work business, Dominique began a local office stationery business in Western Sydney. In those early days COS had two staff and the leading selling item was typewriter ribbon.
40 years of amazing development
40 years later on COS sells over 21,000 products with over 350 staff, and offices and storage facilities in every state and territory. COS is still owned and managed by Dominique, who is now joined by daughters Belinda and Amie who hold key executive roles.
COS’ development and success is a testament to Dominique’s drive, enthusiasm and vision. In 2014 he was among four finalists in the prestigious Ethnic Business Awards where the amazing development of COS from a small company to a significant factor within the Australian economy was acknowledged and recognised.
COS is now the largest 100% Australian owned and run National Office Products company. The exact same enthusiasm and ingenious spirit which Dominique showed 40 years ago still stay as core worths in the way we work and support Australian communities.
